This creature durability to the environment is very high, it can survive high temperatures and anaerobic ecosystems. Archaea can be found inside the human body as human microbiota, they are inside colon, subgingival and vaginal. Harmful Effects of Kingdom Archaebacteria
There are only a few studies about archaebacteria colonization inside the human body and its impacts on human health. However, researchers agree that it can potentially promote disease. Here are some harmful effect of kingdom archaebacteria: 1. Producing sulfuric acid
As a sulfolobus, archaea produce a waste product in a form of sulfuric acid in sulfur cycle in the sulfur-rich environment. Even if they release oxidizing sulfur compounds for another organism, this sulfuric acid can contribute to acid mine drainage and environmental damages. A moderate concentration of sulfuric acid can be dangerous upon contact with skin and cause chemical burns.

 Difficulties in the isolation and cultivation of archaea also contribute to a relative lack of knowledge. No definitive virulence genes or factors have been described in archaea to date. Nevertheless, archaea may have the means, and they certainly have the opportunity, to cause disease. Archaea share some characteristics with known pathogens that may reflect the potential to cause disease. Such characteristics include ample access to a host (i.e., opportunity) and capabilities for long-term colonization and coexistence with endogenous flora in a host. The detection of anaerobic archaea in the human colonic ( 36 ), vaginal ( 2 ), and oral microbial flora ( 1) demonstrates their ability to colonize the human host. Details regarding their survival in such human niches, including human immune system evasion and competition with normal human flora, however, are largely unavailable. Whether or not members of the Archaea possess virulence factors as commonly defined (i.e., the means for causing disease) is unclear. Of course, generalizations about a group of organisms as diverse as archaea are problematic. With this in mind, one might ask whether there are any fundamental features shared by archaea that should preclude them from acting as pathogens.

Might archaea be capable of causing disease? Current data suggest that archaea are able to colonize and survive in humans. However, no concerted efforts have been undertaken to implicate archaea in human disease. The full spectrum of outcomes from these archaea-human interactions, whether it includes altered host physiology, tissue damage, or clinical disease, remains a mystery.

Archaea: Hot springs, the Dead Sea, and your intestines Most humans harbor Archaea in their digestive tracts where they may provide some benefits, such as consuming hydrogen gas produced by bacteria, consuming toxic metabolites resulting from bacterial protein fermentation, and reducing trimethylamine intestinal content. And, despite the many human diseases caused by bacteria—tuberculosis, pneumonia, urinary tract infections, etc.—Archaea are largely benign and appear to not typically cause human diseases. In other words, they seem less opportunistic than bacteria or viruses, benign co-inhabitants in creatures like mammals. This is why it is surprising that evidence is mounting associating the proliferation of Archaea such as Methanobrevibacter smithii, so-called because it produces methane gas rather than hydrogen gas, with a form of small intestinal bacterial overgrowth, SIBO, called methanogenic SIBO. Because methane gas has been shown to slow intestinal propulsive activity in the intestinal tract, the red flag for methanogenic SIBO is constipation. Now, recall that gliadin-derived opioid peptides can be responsible for constipation, as are other opioids, a fact that the ever-enterprising pharmaceutical industry puts to advantage. Gliadin-derived opioid peptides can also be responsible for severe, unremitting constipation, “obstipation,” an awful situation in which sufferers move their bowels every several weeks, partial and temporary relief provided by mega-dose laxatives and enemas. Banishing all gliadin-containing wheat and related grains can therefore provide dramatic relief to many cases of constipation. But Archaea can also cause constipation, often labeled IBS-C or irritable bowel syndrome with constipation. But why?

It seems more likely that periodontal disease causes an enlargement of anaerobic regions in the mouth that are subsequently populated by M. oralis. [ 7]
There remains no good answer as to why archaea do not seem to be pathogenic, but scientists continue to speculate and hope to find the answer.

Archaea: Hot springs, the Dead Sea, and your intestines You can also find them in the guts of ruminants and insects where they assist with digestion. You can even find them at the bottom of the ocean and in Antarctic ice. In other words, they are extremely adaptable, able to survive in conditions that few other organisms can. Some scientists believe that, if we are to discover life on places like the moon or Mars, they are likely to be something like Archaea. I don’t believe that we can classify the human gastrointestinal tract as an extreme environment, though certainly one I would not want to live in. Most humans harbor Archaea in their digestive tracts where they may provide some benefits, such as consuming hydrogen gas produced by bacteria, consuming toxic metabolites resulting from bacterial protein fermentation, and reducing trimethylamine intestinal content.

 Or maybe they have been causing disease all along right under our noses. “There is no inherent reason why archaea should not be involved in diseases. There is no fundamental biological or ecological barrier,” said Torsten Thomas, a microbiologist at the University of New South Wales in Sydney, Australia. “ It has been talked about in the scientific community for many years but nobody has really studied the reasons for the existence or nonexistence of pathogenic archaea.” Thomas thinks that should change. Archaea, he argues, may be responsible for some diseases with no known causes, such as Crohn’s disease, arthritis, lupus and gingivitis, to name some of the better known on his list. Many of his peers disagree, but if Thomas is right, then science is at a loss now to defend us against those diseases. There are no anti-archaeal drugs in development, and these microbes are daunting potential foes because they are poorly understood, hard to study and easily foil common techniques developed to ferret out conventional microbial culprits of disease. So far, the case against archaea is circumstantial, but they have no obvious alibi: archaea live inside us and other animals in guts and orifices – the same places where many diseases take their toll.

Or maybe they have been causing disease all along right under our noses. “There is no inherent reason why archaea should not be involved in diseases. There is no fundamental biological or ecological barrier,” said Torsten Thomas, a microbiologist at the University of New South Wales in Sydney, Australia. “ It has been talked about in the scientific community for many years but nobody has really studied the reasons for the existence or nonexistence of pathogenic archaea.” Thomas thinks that should change. Archaea, he argues, may be responsible for some diseases with no known causes, such as Crohn’s disease, arthritis, lupus and gingivitis, to name some of the better known on his list.

Some scientists have begun peering into those places, this time with an eye out for archaea. In one study, microbiologists at Stanford University teamed up with peridontologists – experts on gum disease – at the University of California, San Francisco to plot the kinds of archaea found in the mouth. “What became apparent fairly quickly was that somebody either had archaea or they didn’t,” said Paul Lepp, now at Minot State University in North Dakota. “ And if they had it, you found it in peridontitis sites.” The more archaea the researchers found, the worse the gum disease.

 Archaebacteria are about 1/10th of a µ meter to about 15 µ meter in size. A few are flagellated and the flagella structure is different from the flagella of other bacteria. The archaebacteria are non-pathogenic bacteria that live in and around other organisms. However, they do not cause any infections or diseases. Sub-groups of Archaebacteria
Archaebacteria are autotrophs and use CO 2 in atmosphere as a source of carbon for a process called carbon fixation. Archaebacteria are able to survive in extreme conditions and therefore also known as extremophiles. They can survive in conditions that are highly acidic, alkaline, saline aquatic environment. Some are even able to survive in temperatures above 100° Celsius or 212° Fahrenheit. Few can even withstand over 200 atmosphere pressure and live really deep within the earth. They employ different chemical reactions to be able to survive in these harsh conditions.

Antibiotics have no effect on archaebacteria, but that’s not a bad thing in terms of our health considering that archaebacteria does not have any effect on humans. Eubacteria, on the other hand, can either help or harm humans. Some eubacteria can be considered “pathogens,” which are bacteria that can cause disease. Some examples include salmonella, staphylococcus, and amoeba can cause disease and infections. However, bacteria such as lactobacillus are known as “probiotics,” which exist in your body right now to help with your health.

Archaebacteria are a type of single-cell prokaryotes microorganism. It was taken out from bacteria kingdom due to significant differences both genetically and biochemically from modern bacteria. Archaebacteria was named from “archae” that means “ancient”. At the beginning, archaebacteria were thought only living in extreme environments some of which are geysers, oil wells, hot springs, volcanoes, and salt lakes, but later they were also found to live in the normal environment. Archaea are usually mutualist or commensals. They play major roles in carbon and nitrogen circle on earth. Archaeabacteria was divided into three major groups based on their metabolism types; they are : Phototrophs; Energy source from sunlight, carbon source from organic compounds

 “I think that the archaea can contribute to pathology and to disease, but I don’t think they do so alone or in a direct manner,” Relman said. Instead, he believes, “They allow other organisms to flourish to a much greater degree than they would otherwise. But it’s a consortium, a group effect. It’s not an effect they are able to carry out on their own.” His hypothesis hinges on the archaea’s diet. Those found in humans and other animals are methanogens – they consume hydrogen made by bacteria and excrete methane gas. ( Not all archaea produce methane, but they are the only creatures that can – it’s one of the differences that sets them apart from the other two domains of life.) Thriving on the waste of other microbes, they clean house, which may allow disease-causing bacteria to multiply. Archaea have a so-called grandfather, Ralph Wolfe, who is skeptical they could cause disease. Wolfe, a microbiologist at the University of Illinois, earned his nickname studying archaea for decades, since before they were given their own taxonomic domain.

 That same year, Japanese researchers examined plaque from 13 coronary arteries and found evidence of archaea in all of them. They published their results in the journal Clinics, concluding that they may be the first to discover disease-causing archaea inside human organs. Lepp warned, however, that their methods may have been flawed in part because they lacked proper experimental controls. Stanford’s David Relman, who headed the American gum disease study, has forged a reputation as an archaea disease hunter. But unlike Torsten Thomas at New South Wales, he does not suspect they could be a direct cause. “I think that the archaea can contribute to pathology and to disease, but I don’t think they do so alone or in a direct manner,” Relman said.

 He worked alongside Carl Woese as the concept of three domains of life gained momentum. Archaea, Wolfe believes, are too primitive and biologically isolated to cause disease in animals, though he does not discount the idea of the consortium effect. “I would say it’s a dead end, but in science you can never tell,” he said. He does agree with Thomas on one point, though: studying archaea is tough, and was harder still when he started his work without the benefit of the technology available today. The old technique, he said, was to swab an abscess, for example, and breed the extracted microbes on agar – a seaweed gelatin that nourishes them. Outside of the body in oxygen-rich open air, only those bacteria that survive in oxygen multiplied. The methanogens and other anaerobes vulnerable to oxygen, if there were any, were smothered. “So,” Wolfe conceded, “unless a laboratory takes a lot of caution to separate anaerobes from the sample then they could be missing something.” Thomas insists that archaea need to be studied further before they can be eliminated as suspects in causing unsolved diseases.

 presented evidence that an archaean called Methanobrevibacter oralis inhabits the gums of patients with periodontal disease. The authors suggested that the activity of these methanogens causes the disease. [ 6] However, it was subsequently shown that there was no causal relationship between M. oralis and periodontitis. It seems more likely that periodontal disease causes an enlargement of anaerobic regions in the mouth that are subsequently populated by M. oralis. [ 7]
There remains no good answer as to why archaea do not seem to be pathogenic, but scientists continue to speculate and hope to find the answer. Key Concepts and Summary
Archaea are unicellular, prokaryotic microorganisms that differ from bacteria in their genetics, biochemistry, and ecology. Some archaea are extremophiles, living in environments with extremely high or low temperatures, or extreme salinity. Only archaea are known to produce methane. Methane-producing archaea are called methanogens. Halophilic archaea prefer a concentration of salt close to saturation and perform photosynthesis using bacteriorhodopsin.

Archaea share some characteristics with known pathogens that may reflect the potential to cause disease. Why Archaea and Bacteria are classified separately? 1 Answer. The reason that Archaea were determined to be a separate (and only the third) kingdom so late (1977 according to this reference) was because archaea often completely resemble eubacteria. But you can see that fungi and other eukaryotes are more similar to archaea than the bacteria. What is older bacteria or archaea? Bacteria are responsible for the break down of dead organic matter. The oldest fossils known, nearly 3.5 billion years old, are fossils of bacteria-like organisms.

The oldest fossils known, nearly 3.5 billion years old, are fossils of bacteria-like organisms.

 Those found in humans and other animals are methanogens – they consume hydrogen made by bacteria and excrete methane gas. ( Not all archaea produce methane, but they are the only creatures that can – it’s one of the differences that sets them apart from the other two domains of life.) Thriving on the waste of other microbes, they clean house, which may allow disease-causing bacteria to multiply. Archaea have a so-called grandfather, Ralph Wolfe, who is skeptical they could cause disease. Wolfe, a microbiologist at the University of Illinois, earned his nickname studying archaea for decades, since before they were given their own taxonomic domain. He worked alongside Carl Woese as the concept of three domains of life gained momentum. Archaea, Wolfe believes, are too primitive and biologically isolated to cause disease in animals, though he does not discount the idea of the consortium effect. “I would say it’s a dead end, but in science you can never tell,” he said. He does agree with Thomas on one point, though: studying archaea is tough, and was harder still when he started his work without the benefit of the technology available today.

 But the evidence wasn’t exactly a smoking gun, since the archaea were present in only about one-third of diseased gums, and shared the space with many other kinds of microbes. They published their results in April 2004 in the journal Proceedings of the National Academy of Sciences. A similar study by scientists in Brazil and Germany found archaea in five out of 20 gum disease samples. They also linked archaea with infectious disease without implicating them explicitly as the cause, according to a paper published in April 2006 in the Journal of Clinical Microbiology. And sights were not just on gum disease. That same year, Japanese researchers examined plaque from 13 coronary arteries and found evidence of archaea in all of them. They published their results in the journal Clinics, concluding that they may be the first to discover disease-causing archaea inside human organs. Lepp warned, however, that their methods may have been flawed in part because they lacked proper experimental controls. Stanford’s David Relman, who headed the American gum disease study, has forged a reputation as an archaea disease hunter. But unlike Torsten Thomas at New South Wales, he does not suspect they could be a direct cause.

 The old technique, he said, was to swab an abscess, for example, and breed the extracted microbes on agar – a seaweed gelatin that nourishes them. Outside of the body in oxygen-rich open air, only those bacteria that survive in oxygen multiplied. The methanogens and other anaerobes vulnerable to oxygen, if there were any, were smothered. “So,” Wolfe conceded, “unless a laboratory takes a lot of caution to separate anaerobes from the sample then they could be missing something.” Thomas insists that archaea need to be studied further before they can be eliminated as suspects in causing unsolved diseases. Even if they are ultimately proven harmless, he says, that finding could be important if it turns out that archaea have a gene that suppresses toxicity – a gene that might be useful someday in stifling the power bacteria have to inflict damage. “I think that if we don’t find any pathogenic archaea it would be very interesting to find out why they aren’t,” Thomas says. “ Obviously that’s the best target to attack in bacteria. If we find something that bacteria do have and archaea don’t have, we need to attack that.” Gut microbes may help prevent type 1 diabetes.

Abstract
Archaea are microorganisms that are distinct from bacteria and eukaryotes. They are prevalent in extreme environments, and yet found in most ecosystems. They are a natural component of the microbiota of most, if not all, humans and other animals. Despite their ubiquity and close association with humans, animals and plants, no pathogenic archaea have been identified. Because no archaeal pathogens have yet been identified, there is a general assumption that archaeal pathogens do not exist. This review examines whether this is a good assumption by investigating the potential for archaea to be or become pathogens. This is achieved by addressing: the diversity of archaea versus known pathogens, opportunities for archaea to demonstrate pathogenicity and be detected as pathogens, reports linking archaea with disease, and immune responses to archaea. In addition, molecular and genomic data are examined for the presence of systems utilised in pathogenesis.

 in the soil, the water, anywhere the rest of life can exist and even where it can’t. That’s when the chin-scratching began. Many bacteria and eukarya are well known pathogens – if you can name the infection, one of them is probably responsible. Yet archaea seemed innocent. Maybe they are, which prompts speculation that they could hold a genetic key to curing disease. Or maybe they have been causing disease all along right under our noses. “There is no inherent reason why archaea should not be involved in diseases. There is no fundamental biological or ecological barrier,” said Torsten Thomas, a microbiologist at the University of New South Wales in Sydney, Australia. “ It has been talked about in the scientific community for many years but nobody has really studied the reasons for the existence or nonexistence of pathogenic archaea.” Thomas thinks that should change.

Archaea in and on the Human Body: Health Implications and Future Directions
Archaea on the human skin have been discovered only in recent years.
 Archaea were initially classified as bacteria and thought to only exist in extreme environments (such as hot springs and salt lakes), and given the name archaebacteria, but this classification is now outdated. We now know that archaea live in less extreme places, including oceans, marshlands, animals, and humans. So little is known about archaea that not even medical schools discuss this topic. This may be due to the fact that we currently don't know of any archaea that are human pathogens (that is, that cause illness) or parasitic. They are generally viewed as mutuals (the relationship is beneficial to both organisms) or commensals (they benefit, but don't help or harm the other organism). Humans appear to have low levels of archaea, and so far they have been found in the human gut (part of digestion and metabolism), on the skin, and in subgingival dental plaque (and perhaps involved with periodontal disease). But studies rarely look for them. We don't know the importance or roles that they play in our bodies (but there are suspicions), but it turns out that drugs such as statins and the antibiotic metronidazole are eliminating them. Note that methanogens are archaea that excrete or produce methane as a metabolic byproduct in anoxic (no oxygen) conditions such as the gut. They help digest our food.

Over the past 50 years, the search for microorganisms in seemingly uninhabitable environments, such as at the extremes of pH, temperature, nutrient concentration, and pressure, has yielded a great deal of information about the diversity and origins of microbial life. Archaea, one of the three domains of life, is a highly diverse and abundant group of prokaryotes, and includes a number of “extremophiles” that thrive in such environments as hot springs, salt lakes, and submarine volcanic habitats ( 33 ). Recent molecular studies have also revealed that archaea, like bacteria, are commonly mesophilic ( 10 ). It is puzzling that despite being one of the most numerous and ubiquitous life forms on earth, no member of the domain Archaea has been described as a human pathogen ( 47) (Fig. 1 ). Open in new tab

 Some scientists have begun peering into those places, this time with an eye out for archaea. In one study, microbiologists at Stanford University teamed up with peridontologists – experts on gum disease – at the University of California, San Francisco to plot the kinds of archaea found in the mouth. “What became apparent fairly quickly was that somebody either had archaea or they didn’t,” said Paul Lepp, now at Minot State University in North Dakota. “ And if they had it, you found it in peridontitis sites.” The more archaea the researchers found, the worse the gum disease. But the evidence wasn’t exactly a smoking gun, since the archaea were present in only about one-third of diseased gums, and shared the space with many other kinds of microbes. They published their results in April 2004 in the journal Proceedings of the National Academy of Sciences. A similar study by scientists in Brazil and Germany found archaea in five out of 20 gum disease samples.

Archaea in and on the Human Body: Health Implications and Future Directions
Archaea on the human skin have been discovered only in recent years.
 ... archaea are still an under-detected and little-studied part of the human microbiome, and their contributions to human health or disease remain mostly unknown. This knowledge gap should be addressed in the near future to inform clinicians, many of whom are totally unaware of these organisms. While no human clinical study studying the in vivo effects of statins on archaea in our microbiomes has been published, in vitro results strongly suggest that these drugs could inhibit the growth of archaea in the human body... Moreover, in highly competitive niches, such as the colon, even partial growth inhibition may cause extinction. In developed countries, such as the United States, statin use is on the rise, and over a third of people over 65 use these drugs for their cholesterol-lowering effects, unaware that at the same time they are taking a broad-spectrum anti-archaeal agent. At the moment, there is little evidence of whether eradication of human-associated archaea (and potentially their bacterial syntrophs) will be beneficial or harmful for human health, with the possible exception of periodontal disease. Thus, before archaea become part of the "disappearing human microbiota" we should at least know if we are going to miss them when they are gone. Post navigation

 there are 10 times more bacteria in the gut than there are human cells in the entire human body. Most of the bacteria in the human body are helpful, like gut bacteria, or harmless. However, some bacteria can infect humans and cause diseases such as cholera, syphilis, and tuberculosis. Archaea
Archaea are single-celled microorganisms that look very similar in size and shape to bacteria. The word archaea comes from the ancient Greek word ἀρχαῖα, which means “ancient things”. They were historically classified as bacteria, but have some characteristics that are more closely related to eukaryotes, such as certain genes and forms of metabolic pathways. Also, they were classified as the third domain of life because they have large differences in their ribosomal RNA structure from bacteria. Some archaea live in extreme conditions such as hot springs, but others are found in soil, oceans, and even the human body. There are between 18-23 phyla of archaea. Most archaea have never been isolated in the laboratory, and they are only known from their nucleic acids in environmental samples.

Abstract
MeSH terms
Substances
 Because no archaeal pathogens have yet been identified, there is a general assumption that archaeal pathogens do not exist. This review examines whether this is a good assumption by investigating the potential for archaea to be or become pathogens. This is achieved by addressing: the diversity of archaea versus known pathogens, opportunities for archaea to demonstrate pathogenicity and be detected as pathogens, reports linking archaea with disease, and immune responses to archaea. In addition, molecular and genomic data are examined for the presence of systems utilised in pathogenesis. The view of this report is that, although archaea can presently be described as non-pathogenic, they have the potential to be (discovered as) pathogens. The present optimistic view that there are no archaeal pathogens is tainted by a severe lack of relevant knowledge, which may have important consequences in the future.

Archaea are a group of micro-organisms that are similar to, but evolutionarily distinct from bacteria. Many archaea have been found living in extreme environments, for example at high pressures, salt concentrations or temperatures. These types of organisms are called extremophiles. Their cell wall differs in structure from that of bacteria and is thought to be more stable in extreme conditions, helping to explain why some archaea can live in many of the most hostile environments on Earth. Examples of archaea habitats are boiling hot springs and geysers such as those found in Yellow Stone Park, USA and ice such as the Arctic and Antarctic oceans, which remain frozen for most of the year.

We Have Archaea In and On Our Bodies
Archaea in and on the Human Body: Health Implications and Future Directions
Archaea on the human skin have been discovered only in recent years.
 Methanogenic Archaea have been reported in subgingival dental plaque as early as 1987. To date, three genera have been successfully isolated from subgingival plaque: Methanobrevibacter Methanobrevibacter, Methanosphaera (based on weak antigenic similarity), and Methanosarcina ...
Unlike many antibiotics that do not target archaea (because they do not have a peptidoglycan cell wall and have ribosomes that are more eukaryotic like, metronidazole, which is commonly used to treat periodontitis, is highly effective against M.oralis and, thus, suppression of M. oralis could contribute to its efficacy. Statins... lower blood cholesterol in humans, but they also effectively inhibit archaeal growth because they block the synthesis of their main membrane lipids. Archaea on the human skin have been discovered only in recent years. ... archaea are still an under-detected and little-studied part of the human microbiome, and their contributions to human health or disease remain mostly unknown. This knowledge gap should be addressed in the near future to inform clinicians, many of whom are totally unaware of these organisms. While no human clinical study studying the in vivo effects of statins on archaea in our microbiomes has been published, in vitro results strongly suggest that these drugs could inhibit the growth of archaea in the human body... Moreover, in highly competitive niches, such as the colon, even partial growth inhibition may cause extinction. In developed countries, such as the United States, statin use is on the rise, and over a third of people over 65 use these drugs for their cholesterol-lowering effects, unaware that at the same time they are taking a broad-spectrum anti-archaeal agent. At the moment, there is little evidence of whether eradication of human-associated archaea (and potentially their bacterial syntrophs) will be beneficial or harmful for human health, with the possible exception of periodontal disease.

Think about It
 The genomes of Archaea are larger and more complex than those of bacteria. Domain Archaea is as diverse as domain Bacteria, and its representatives can be found in any habitat. Some archaea are mesophiles, and many are extremophiles, preferring extreme hot or cold, extreme salinity, or other conditions that are hostile to most other forms of life on earth. Their metabolism is adapted to the harsh environments, and they can perform methanogenesis, for example, which bacteria and eukaryotes cannot. The size and complexity of the archaeal genome makes it difficult to classify. Most taxonomists agree that within the Archaea, there are currently five major phyla: Crenarchaeota, Euryarchaeota, Korarchaeota, Nanoarchaeota, and Thaumarchaeota. There are likely many other archaeal groups that have not yet been systematically studied and classified. With few exceptions, archaea are not present in the human microbiota, and none are currently known to be associated with infectious diseases in humans, animals, plants, or microorganisms. However, many play important roles in the environment and may thus have an indirect impact on human health.

Archaebacteria: Extreme environments
Eubacteria: Everywhere
You can find eubacteria everywhere – even inside you. Don’t worry, though: most of these bacteria are harmless so you won’t be able to feel it or see any effects. However, too much bacteria or coming into contact with certain eubacteria can cause negative health effects that you may notice. Archaebacteria, however, can only be found in extreme environments like hydrothermal vents, hot springs, and highly saline, acidic, and anaerobic environments, so they’re a relatively rarer bacteria to find. Reproduction

Archaebacteria: Asexually (Fission, budding, fragmentation)
Eubacteria: Spores to remain dormant through non-inhabitable conditions
Archaebacteria reproduce through means such as fission (splitting into two), budding (growing a new organism from an existing organism), and fragmentation (splitting an organism into multiple pieces and then growing new organisms from those pieces).

 Yellowstone National Park's boiling hot springs was one of the first places Archae was discovered. Archaebacteria have a size between 1/10th of a micrometer to over 15 micrometers. ( A human hair is about 100 micrometers in width.) Some possess flagella, but these are substantially different in structure than the flagella bacteria have. In 1999, Pyrococcus abyssi, one of the toughest archaebacteria on Earth, had its genome sequenced. Further study of its resilience to extreme temperatures is expected to have applications in the biotechnology industry. Archaebacteria are non-pathogenic, living in and around other organisms but not infecting them. Some are able to withstand pressures of above 200 atmospheres, allowing them to thrive deep within the Earth. Is Amazon actually giving you the best price?

 Here are a few of their roles. Types of Microorganisms
Bacteria
Bacteria – now sometimes called “ eubacteria ” or “true bacteria” to differentiate them from archaebacteria – are the type of microorganism you probably hear about the most. This is because they’re the type most likely to make you sick. Bacteria are the cause of most skin infections, and can also cause food poisoning, pneumonia, strep throat, and many other illnesses. However, bacteria are also very helpful to humans. “ Good bacteria” in our digestive tracts help us to extract nutrients from our food, and help to fight pathogens that could hurt us. Archaea
Archaea, or archaebacteria, were once thought to be part of the bacteria family. However, recent research has shown that they are much different from eubacteria, and may even be more closely related to us than they are to modern bacteria. Archaea can be found in many of the same places as bacteria – in water, in soil, and inside our digestive tracts, where they help us to stay healthy. However, archaebacteria can also be found in some unusual places – many are able to live in environments that are very hot, very cold, very acidic, or very salty.

 In fact, the extreme pink color of some salt ponds, like those in San Francisco, is actually due to the pink pigments produced by the Archaea growing in the water. Extreme halophiles, like Halobacterium and Natronobacterium, are only able to thrive in these high-salt environments. One note here: Archaea in this group are able to survive salt-based food preservation methods like used with meats and fish. But no pathogenic Archaea have been discovered yet, so you are not going to get sick from consuming these organisms. As is the case in science, this could change at any time. But it seems that Archaea did not evolve to cause disease in mammals. Thermoacidophiles
There are also Archaea that are thermoacidophiles. These organisms grow best at high temperatures and extremely low pH. For many Archaea, this means a pH less than 2, the same pH as stomach acid. One genus of Archaea, called Picrophilus, can even survive pH values below zero.

In fact, the extreme pink color of some salt ponds, like those in San Francisco, is actually due to the pink pigments produced by the Archaea growing in the water. Extreme halophiles, like Halobacterium and Natronobacterium, are only able to thrive in these high-salt environments. One note here: Archaea in this group are able to survive salt-based food preservation methods like used with meats and fish. But no pathogenic Archaea have been discovered yet, so you are not going to get sick from consuming these organisms. As is the case in science, this could change at any time.

 Archaebacteria are probably little changed from the organisms that first evolved billions of years ago. They are capable of living in extremely harsh environments, such as salt marshes, hot springs, or even beneath the ice. Eubacteria evolved later. Some are photosynthetic bacteria; some are chemosynthetic bacteria, making carbohydrates from other chemicals besides carbon dioxide; and some are heterotrophic bacteria, deriving nutrients from the environment. Heterotrophic prokaryotes include some pathogens, bacteria that cause diseases, such as pneumonia, food poisoning, and tuberculosis. Two typical prokaryotic cells: a blue-green alga and a bacteria.

 Others are chemoautotrophic; they produce their own food through chemical sources. Still others are heterotrophic. These bacteria cannot make their own food and need to obtain it from other living things. Human beings contain many bacteria which enable us to digest food; there are 10 times more bacteria in the gut than there are human cells in the entire human body. Most of the bacteria in the human body are helpful, like gut bacteria, or harmless. However, some bacteria can infect humans and cause diseases such as cholera, syphilis, and tuberculosis. Archaea
Archaea are single-celled microorganisms that look very similar in size and shape to bacteria. The word archaea comes from the ancient Greek word ἀρχαῖα, which means “ancient things”.

 The biodiversity of Deep Lake is low, and is dominated by Archaea of the family Halobacteriaceae. To date, only three psychrophilic archaeal strains, all free-living and members of the subdomain Eukaryarchaeota, are available in pure culture. Methanococcoides burtonii ( Tmin −2.5°C) and Methanogenium frigidum ( Tmin −10°C) were originally isolated from the bottom of Ace Lake, Antarctica, where the methane-saturated waters remain between 1 and 2°C.

Archaea (overview)
S. DasSarma, ... P. DasSarma, in Encyclopedia of Microbiology (Third Edition), 2009
Introduction
Archaea are prokaryotic microorganisms that are members of the third branch (or domain) of life, distinct from the other two domains – Bacteria and Eucarya. Archaea were recognized as a coherent group in the tree of life using small ribosomal RNA (rRNA) sequence comparisons by C. R. Woese and coworkers in 1977. Archaea have been detected in nearly all environments examined using culture-independent molecular techniques, including 16S rRNA sequencing. However, most well-characterized Archaea have been cultured from extreme environments that are very salty, acidic, alkaline, hot, cold, or anaerobic where they are sometimes dominant. Methanogenic Archaea have been detected in the mammalian gastrointestinal tract, but no archaeal species causing disease has been identified thus far. Many Archaea are chemoautotrophs and can grow on simple inorganic chemicals, others are heterotrophs and grow on complex organic materials, and a few have phototrophic capabilities and can use light energy for growth.

The high levels of archaea in the intestines can cause malabsorption, preventing the body from properly utilizing nutrients. Because food is not breaking down properly in the digestive tract, it causes a number of digestion issues as the body processes. This could be food rotting in the stomach, food not being removed from the body, or numerous other issues listed below. Archaea, like bacteria, like to eat carbohydrates. When there is an overabundance of carbohydrates in the intestines that are not absorbed into our body these microorganisms are going to consume these carbohydrates. and thus these carbohydrates are going to ferment. This fermentation of these carbohydrates is going to cause damage to the intestinal tract cells causing a “leaky gut” or a malabsorption syndrome. IMO organisms create methane gas as a byproduct.

Archaebacteria Facts Archaebacteria Facts
Archaebacteria Facts Their membranes are more rigid. Some Archaebacteria are considered Phototrophs (energy derived from the sun), or Lithotrophs (energy derived from inorganic compounds), or organotrophs (energy derived from organic compounds). Archaebacteria make up approximately 20% of the oceans' microbial cells. Archaebacteria can be found in oil wells, geysers, acidic water, alkaline water, swamps, marshes, sewage, soil, and the intestinal tract of animals. Archaebacteria are considered to be one of the earth's oldest forms of life. They survived the extinction events that killed off the dinosaurs. Archaebacteria can be found in scorching hot deserts and in semi-frozen Arctic waters. There are no malicious Archaebacteria species known to exist. In sewage treatment plants there is enough Archaebacteria to commercially manufacture methane gas. While scientists are excited by the discovery that Archaebacteria are a new primary kingdom of life, it is the information Archaebacteria may be able to provide about early life on earth that they are most excited about.

 These bacteria are not a source of any illness in humans. They contain a distinctive rRNA (Ribosomal ribonucleic acid) i.e. RNA constituent of the ribosome, important for the protein synthesis and this distinctive feature makes them different from their fellow prokaryotes. Archaebacteria play a significant role in biogeochemical cycles like the carbon cycle and nitrogen cycle. The biochemical activity in archaebacteria is diverse and is dependent on various substrates for getting energy and carbon Archaebacteria have been recognised to reproduce asexually occurring by binary fission, fragmentation and even budding. Archaebacteria are mostly extremophiles as they have the ability to thrive in extreme conditions of acidic environments, extreme saline conditions, high temperatures, pressure or chemical concentration and all these conditions are detrimental to most of the life on planet earth. They are categorised into three main types: crenarchaeota, euryarchaeota and korarchaeota. Crenarchaeota are the most abundant archaebacteria that account for around 20% of the microorganisms in the form of picoplankton (photosynthesis performing phytoplanktons consisting of cells that range from 0.2 and 2 μm) in the global oceans. These thrive in either very hot (hyperthermophiles), very cold (thermoacidophiles i.e. extremophilic microorganisms that are both thermophilic and acidophilic) and acidic conditions like the hot springs and submarine hydrothermal vents. Euryarchaeota comprise of halophiles (organisms growing in saline conditions) and methanogens (methane producing bacteria that survives in saline and oxygen lacking environments).

 There are three basic bacterial cell shapes: cocci, bacilli and spirilla. The cocci are oval or spherical bacteria, the bacilli are rod-shaped and the spirilla are spirals. Bacteria play an important role in human disease and health. Some of these microbes, like Staphylococcus aureus, can cause infections in people. However, other bacteria are beneficial, such as Lactobacillus acidophilus, which helps your body break down lactose found in dairy products. Archaea: The Basics
Initially classified as ancient bacteria and called "archaeobacteria," archaea now have their own domain. Many species of archaea are extremophiles and live in extreme conditions, such as boiling hot springs or acidic water, which bacteria cannot tolerate. Some examples include hyperthermophiles that exist in temperatures above 176 degrees Fahrenheit (80 degrees Celsius) and halophiles that can live in salt solutions that range from 10 to 30 percent.

 A Review on Recent Diseases Caused by Microbes
Microbes are called disease-causing microbes and can make humans, animals and plants sick by causing infection and disease. Disease-causing microbes can also be called pathogens, germs or bugs and are responsible for causing infectious diseases. Microorganisms are very diverse. They include all of the prokaryotes, namely the bacteria and archaea and various forms of eukaryotes, comprising the protozoa, fungi, algae, microscopic plants (green algae), and animals such as rotifers and planarians. Some microbiologists also classify viruses as microorganisms, but others consider these as nonliving. This review deals with the current status of disease causing microbes and the recent diseases which mostly went unnoticed. A Review on Recent Diseases Caused by Microbes

What are Archaebacteria and Eubacteria? Archaebacteria
Archaebacteria, also termed as ‘archaea’ constitute a kingdom of microorganisms having a single cell. The word ‘archaea’ comes from an ancient Greek word ἀρχαῖα meaning ‘ancient things’. T hese are prokaryotes (organisms without a well-defined nucleus). Archaebacteria and bacteria are thought to be alike in size and structure but scientist discovered that they show radical difference in their molecular organisation due to which they have now earned their own category. These bacteria are not a source of any illness in humans. They contain a distinctive rRNA (Ribosomal ribonucleic acid) i.e. RNA constituent of the ribosome, important for the protein synthesis and this distinctive feature makes them different from their fellow prokaryotes. Archaebacteria play a significant role in biogeochemical cycles like the carbon cycle and nitrogen cycle.

When a person develops a bacterial infection, the most effective cure is through antibiotics. Antibiotics kill bacteria by attacking their cell walls, interfering with bacteria from reproducing in a certain area. Eubacteria can be killed by antibiotics because it has substances that can destroy its functions. For archaebacteria, however, antibiotics will have no effect on it. This is not to say, however, that all antibiotics are effective in killing eubacteria. Lately, antibiotic resistance has become an issue. Eubacteria is slowly evolving to become resistant to antibiotics, making it difficult for doctors to treat infections. Effect on Humans

 It also protects the cell from bursting under hypotonic conditions. The cell wall is composed of Pseudomurein, which prevents archaebacteria from the effects of Lysozyme. Lysozyme is an enzyme released by the immune system of the host, which dissolves the cell wall of pathogenic bacteria. These do not possess membrane-bound organelles such as nuclei, endoplasmic reticulum, mitochondria, lysosomes or chloroplast. Its thick cytoplasm contains all the compounds required for nutrition and metabolism. They can live in a variety of environments and are hence called extremophiles. They can survive in acidic and alkaline aquatic regions, and also in temperature above boiling point. They can withstand a very high pressure of more than 200 atmospheres. Archaebacteria are indifferent towards major antibiotics because they contain plasmids which have antibiotic resistance enzymes. The mode of reproduction is asexual, known as binary fission.

Abstract
Microbes are called disease-causing microbes and can make humans, animals and plants sick by causing infection and disease. Disease-causing microbes can also be called pathogens, germs or bugs and are responsible for causing infectious diseases. Microorganisms are very diverse. They include all of the prokaryotes, namely the bacteria and archaea and various forms of eukaryotes, comprising the protozoa, fungi, algae, microscopic plants (green algae), and animals such as rotifers and planarians. Some microbiologists also classify viruses as microorganisms, but others consider these as nonliving. This review deals with the current status of disease causing microbes and the recent diseases which mostly went unnoticed.

Archaebacteria play a vital role in carbon cycle and nitrogen cycle. Their pathogenic or parasitic effect is still not observed. Archaebacteria are metabolically diverse, using a variety of substrates as their energy and carbon sources. Asexual reproduction of archaebacteria is identified, occurring by binary fission, budding and fragmentation. Individual archaebacterium is 0.1-15 μm in diameter. Different shapes are processed by archaebacteria like spheres, rods, plates and spirals. Some cells are flat or square-shaped.

 Due to their thinner cell walls, Gram-negative bacteria are more prone to mechanical breakage, but the presence of a phospholipid membrane makes it more difficult for antibiotics to interact with the cell wall. Thus, Gram-negative bacteria tend to be more resistant to traditional antibiotics whose mechanism of action involves disrupting the structure of the bacterial cell wall. Archaea
The existence of archaea is actually a rather new development in biology. For the longest time, archaea were considered as a particular kind of bacteria, called archaebacteria. Archaea were first identified as separate from bacteria in 1977 by the biologists Carl Woese and George Fox. Although very similar in shape and size to bacteria, archaea have a unique phylogenetic lineage and contain cellular mechanisms that are more analogous to those found in eukaryotic organisms. Additionally, there is currently no know pathogenic archaea, meaning that archaea do not make people sick like bacteria do. Archaea are known for being extremophiles, favoring condition and environments that most organisms would be destroyed in. Archaea have been observed living in deep ocean thermal vents where average temperatures are greater than 100° C and in bodies of water with a salt content too high for other kinds of organisms. It was originally thought that all archaea were extremophiles, but archaea have been found living in relatively mundane environments like mud, grasslands, and freshwater lakes.

 Many archaea are famous for being able to survive in extreme conditions (hot, salty, or acidic), which earns those archaeal species the name extremophiles. However, not all archaea are extremophiles. So far, no disease-causing archaea have been discovered. Examples: hot spring dwelling Sulfolobus
salt-loving Haloarchaea
human gut-dwelling Methanobrevibacter
Where you can find them: you can find archaea anywhere you find bacteria, which is nearly everywhere; you may not be able to see archaea extremophiles on a daily basis, but if you have the chance, go see them in the hydrothermal waters of Yellowstone National Park ( go see the Grand Prismatic Spring) and salty environments like the Dead Sea and the Great Salt Lake. However, we have archaea living on (skin) and in (gut, mouth) us as a part of our microbiome. So, you can also simply know that you are carrying them with you all the time. Archaea appear as the cream or yellow-colored sections of the Grand Prismatic Spring at Yellowstone National Park.

 Archaebacteria can only reproduce through the asexual mode. FAQ (Frequently Asked Questions)
1. Explain Archaebacteria with Help of Some Examples. Following listed below are some examples of archaebacteria:-
Lokiarchaeota:- This is a thermophilic archaebacteria and is Generally found in the deep sea vents, which are known as Loki’s castle. Lokiarcheota has a unique genome, some of the genes of the genome are involved in phagocytosis. It is assumed that Lokiarcheota and eukaryotes shared a common ancestor billions of years ago, maybe due to which it also possesses eukaryotic genes that are used by eukaryotes to maintain their shapes. Methanobrevibacter Smithii:- This bacteria produces methane and is usually found in the human gut. It plays an important role in the breakdown of plant sugar, and also helps us to extract energy and also helps us to extract energy from the food consumed by us. The chances of this bacteria being present in our gut increases for the people suffering from obesity and colon cancer. 2.

In what type of environments can archaebacteria be found? - Quora In what type of environments can archaebacteria be found?
In what type of environments can archaebacteria be found? They are also part of the human microbiota, found in the colon, mouth, and skin. Archaea are particularly numerous in the oceans, and the archaea in plankton may be one of the most abundant groups of organisms on the planet. Archaea are a major part of Earth's life and may play roles in both the carbon cycle and the nitrogen cycle. No clear examples of archaeal pathogens or parasites are known, but they are often mutualists or commensals. One example is the methanogens that inhabit human and ruminant guts, where their vast numbers aid digestion. Methanogens are also used in biogas production and sewage treatment, and biotechnology exploits enzymes from extremophile archaea that can endure high temperatures and organic solvents. 642 views

Archaebacteria vs Eubacteria
Archaebacteria and Eubacteria are both prokaryotic, though these organisms exist in different biological domains because they are so genetically different. It is thought that archaebacteria are some of the oldest forms of life on Earth, while eubacteria arose later in evolutionary history. Eubacteria are now found in almost all environments, whereas archaebacteria have been pushed to only the most extreme environments – such as high salinity lakes, thermal hot springs, and deep within the Earth’s crust. There are a few other differences between these groups. For instance, archaebacteria are not susceptible to antibiotics, while most eubacteria are (unless they have developed resistance.) Archaebacteria typically do not infect humans (or aid in digestion), so this is generally not a problem for human health. Further, eubacteria have the ability to form spores to survive adverse conditions, while archaebacteria do not have this ability. Types of Eubacteria
Bacteria commonly take on one of three shapes: bacilli, cocci, and spirilla.

 As is the case in science, this could change at any time. But it seems that Archaea did not evolve to cause disease in mammals. Thermoacidophiles
There are also Archaea that are thermoacidophiles. These organisms grow best at high temperatures and extremely low pH. For many Archaea, this means a pH less than 2, the same pH as stomach acid. One genus of Archaea, called Picrophilus, can even survive pH values below zero. Many geothermal hot springs have very low pH due to the high sulfuric acid content. Even the combination of harsh environmental conditions like heat and acid can't seem to stop the Archaea from growing happily. Diverse Metabolism
All Archaea are chemotrophic, meaning they use chemicals to obtain energy. Some use organic compounds, like sugars, while others use inorganic compounds, like iron. One of the most common inorganic energy sources used by Archaea is hydrogen gas.

 Their ability to tolerate extreme conditions helps researchers learn about the climatic conditions, environment and their survival on ancient earth. Methanogens can grow in biogas fermentors and decompose cow dung into methane gas as a by-product. Thus, they are used for production of domestic gas for cooking. Organisms like Methanobacterium ruminantium are present in the guts of ruminating animals, helping them digest the cellulose. Poor ores of molybdenum are microbial leached using Sulfolobus. Archaebacteria are also used to synthesize thermophilic enzymes, restriction enzymes and are also used as biosensors. Archaebacteria have an important role in many chemical cycles, like carbon cycle, nitrogen cycle, sulfur cycle, etc. Due to their extremophilic nature, archaebacteria have proven to be of great help in the field of Bioechnology, by helping in the production of enzymes that work at very high temperatures, as well as in the production of some antibiotics.

Definition: Similar to bacteria, archaea are single-celled prokaryotes. But they differ from bacteria in the structure of their cell walls (if they have one). Many archaea are famous for being able to survive in extreme conditions (hot, salty, or acidic), which earns those archaeal species the name extremophiles. However, not all archaea are extremophiles. So far, no disease-causing archaea have been discovered. Examples: hot spring dwelling Sulfolobus
salt-loving Haloarchaea

 One Archaea, Methanopyrus kandlerithrives at 122°C, the highest recorded temperature at which any organism will grow.[7] Other extremophiles, called halophiles, live in hypersaline environments, meaning that they are very salty. Archaea are also commonly found in cold oceanic environments, such as the polar seas. Not all Archaea, however, are extremophiles, some live in marshland, sewage, oceans, soils, and even inside people. The Archaea found in the world’s oceans in the plankton community are believed to assist in the all-essential oceanic nitrogen cycle. [ 8]
Archaea contribute up to 20% of the Earth’s total biomass and are part of the earth’s natural recycling process; they recycle elements such as carbon, nitrogen, and sulfur. However, they can also contribute to changes that humans have made in the environment, and even cause pollution.[7] Archaea do not need sunlight or oxygen, instead they absorb carbon dioxide(CO2), nitrogen(N2), or hydrogen sulfide(H2S), and give off methanegas. [ 8]
Archaea have formed symbiosis with many other organisms on earth. Interactions between Archaea and other organisms are either mutualism, where each individual derives a fitness benefit, or commensal, where one benefits and the other is not significantly harmed or benefited. Protozoaare a famous example of the Archaea mutualism with another organism;

Archaebacteria are the oldest living organisms on earth. They are prokaryotes and unicellular. Archaebacteria are found in very harsh conditions (such as at the bottom of the sea or in volcanic vents). This is thought to be because the early Earth’s atmosphere was filled with poisonous gases and was very hot – nothing could survive, except the archaebacteria. These slowly gave way to modern organisms when the Earth’s conditions settled down and oxygen was introduced to the atmosphere. There are three phyla, or groups, of archaebacteria.
