 Nematoda - Digestive System

Ascaris
Ascaris is a genus of parasitic nematode worms known as the "giant intestinal roundworms". Some species typically infect pigs, while others, affects human populations, typically in the sub-tropical and tropical areas with poor health conditions that allow for ascaris worms to infect human beings. Its digestive tract ingests food, breaks macromolecules into their subunits, and allows for the absorption of glucose and amino acids. This animal has some a mouth structure for the ingestion of food that is connected to a tube, which passes through the body of the worm and terminates at an anus, where undigested waste products are excreted. The ascaris' digestive tract includes one muscular structure to ensure that food moves through the tract in the proper direction. Finally, it includes an intestinal region in which absorption of small molecules take place, such as gulcose and amino acids. Pinworm
The pinworm, also known as the threadworm or seatworm, but most formally known as the Enterobius vermicularis, is a very common intestinal parasite that infect humans, mostly children. Enterobiasis refers to the disease associated with the pinworm infestation in the body. Pinworms are the most common type of roundworms found in the USA. They are parasites that feed off of the human body to survive and reproduce.

Ascaris Parasitic Worms
You read that right, in this lesson we will talk about parasitic worms, specifically a genus called Ascaris. So we've all heard the term 'parasite', but what does it actually mean? Well, a parasite is an organism that feeds off of or lives within another organism, called a host, to the detriment of that host organism. Now, since we are specifically talking about parasitic worms, rather than, say flies (such as mosquitos), fish (such as the toothpick fish), or insects (like a flea or tick), we can use the term helminth, which specifically refers to parasitic worms.

Ascaris lumbricoides, giant intestinal worms

Classification in Phylum Nematoda
So, we've established that Ascaris is a genus of helminth. They belong to the Kingdom Animalia (just like us), and the Phylum Nematoda (from the Greek 'nematos' meaning 'thread'). Nematoda is the phylum containing all roundworm species. But, in spite of the fact that nematodes are 'roundworms', that does not mean that all worms that are round in shape are nematodes. The term nematoda actually refers, not to their body shape, but to their digestive tract, which is tube-like with tapered openings at either end. Nematodes are pseudocoelomates, meaning they have a 'fake' coelom.

 Ascariasis is treated with anti-parasite medications, resulting in the host passing the ascaris worms naturally, while some advanced cases might require surgery. One such advanced case, which was diagnosed posthumously (after death), was a young child who had 796 Ascaris lumbricoides worms weighting a total of 19 oz encased within her intestines. Prevention of ascariasis includes the ever important washing of hands as well as increased sanitation, whether that be properly functioning toilets or active and proper disposal of human waste as well as the termination of human feces as a fertilizing agent. Lesson Summary
Ascaris worms are a genus of helminths (parasitic worms), meaning that they live off of a host organism, to the detriment of that host. The two most common species are Ascaris suum and Ascaris lumbricoides. While A. suum generally infects pigs, they can infect humans as well. Ascaris are soil-transmitted helminths that infect via the consumption of contaminated soil or foods grown in soil contaminated with Ascaris eggs and belong to the Phylum Nematoda , the phyla designation of all roundworms. Nematodes are pseudocoelomates, ('fake' coelomates), meaning that their fluid filled cavity isn't encased in mesoderm and makes direct contact with their intestinal wall. Ascariasis infections currently affect some 1-2 billion people, with the greatest population being sub-Saharan Africa, Latin America, and Asia. Symptoms include:

Nematodes are pseudocoelomates, meaning they have a 'fake' coelom. A coelom is a body cavity that surrounds the digestive track. In nematodes, their pseudocoelom, or fluid filled cavity, isn't encased in mesoderm but makes direct contact with their intestinal wall. Cross-section of coelomate and pseudocoelomate

What should also be noted is that not all nematodes are parasitic, although, of the approximately 12,000 known species (some estimate that there may be as many 500,000 species because so little is known of their diversity), about half are of the parasitic persuasion. Parasitic Action of Ascaris Worms
Of the 17 species of known Ascaris worms, the two most common species are Ascaris suum and Ascaris lumbricoides, and these helminths can both be found occupying human hosts- gross, right? With that said, A. suum prefers pigs (both domestic and wild alike) but they will certainly take up residence in you or I if given the chance.

Pinworms are common human intestinal parasites, especially in children. They are also found in other vertebrates. Male pinworms are 2 to 5 mm (about 0.08 to 0.2 inch) long; females range in length from 8 to 13 mm. The long tails of the worms give them a pinlike appearance. pinworm

Ascariasis
Enterobius
 Two major types of roundworms that commonly infect humans include Ascaris and Enterobious. Ascariasis is a disease that is caused by the parasitic roundworm Ascaris lumbricoides and is transmitted by ingesting food contaminated with Ascaris eggs. Enterobius, referred to as pinworm, causes enterobiasis and is commonly found in the intestine of children. The entire life cycle of the pinworm occurs within the human gastrointestinal tract. Key Terms
visceral: of or relating to the viscera – the internal organs of the body
nematode: A small invertebrate animal of the phylum Nematoda. Nematodes, or roundworms, are the most diverse phylum of pseudocoelomates and one of the most diverse animal phyla. Nematodes are characterized by the presence of a tubular digestive system with openings at both ends. They can be found in various ecosystems ranging from the polar regions to the tropics, fresh to marine water and various terrestrial environments ranging from mountains, deserts and oceanic floors.

Drawings:
Use a PENCIL!!
Make the drawings “larger than life” size, as the specimens are so small.
Draw the general shape (outline) and location of the organs, as the squiggles so many of you use to “shade” your drawings make your drawings sloppy and hard to interpret.
Include Labels on all drawings.
Labels should start outside the drawing, and be connected to the structure by arrows with tips (===>).
The Tip of the arrow should be touching the structure.
Be sure to include the magnification for any drawings done with the dissecting microscope.
Hang on to the drawings; they will all be handed in later, together with some questions to answer!

 They are covered with a thick protective cuticle that is flexible and can be molted. They have separate sexes generally and reproduce sexually. The roundworm Trichinella, causes the disease called trichinosis . People get trichinosis from eating undercooked pork. Trichinella gets into muscles and leaves calcium deposits which effect muscle contraction. Trichinosis can affect the heart. Another roundworm, Ascaris, parasitizes human lungs. The Filaria worm attacks the lymphatic system causing great swelling. Hookworms and pinworms are also roundworms which parasitize humans. Rotifers
The phylum Rotifera includes microscopic worms found in aquatic and soil habitats.

Want to watch this again later? Log in or sign up to add this lesson to a Custom Course. Ascaris Parasitic Worms
You read that right, in this lesson we will talk about parasitic worms, specifically a genus called Ascaris. So we’ve all heard the term ‘parasite’, but what does it actually mean? Well, a parasite is an organism that feeds off of or lives within another organism, called a host, to the detriment of that host organism. Now, since we are specifically talking about parasitic worms, rather than, say flies (such as mosquitos), fish (such as the toothpick fish), or insects (like a flea or tick), we can use the term helminth, which specifically refers to parasitic worms. Ascaris lumbricoides, giant intestinal worms

Classification in Phylum Nematoda
So, we’ve established that Ascaris is a genus of helminth. They belong to the Kingdom Animalia (just like us), and the Phylum Nematoda (from the Greek ‘nematos’ meaning ‘thread’). Nematoda is the phylum containing all roundworm species. But, in spite of the fact that nematodes are ’roundworms’, that does not mean that all worms that are round in shape are nematodes.

Phylum Nematoda (the roundworms) is a diverse group containing more than 15,000 species, of which several are important human parasites (Figure 1). These unsegmented worms have a full digestive system even when parasitic. Some are common intestinal parasites, and their eggs can sometimes be identified in feces or around the anus of infected individuals. Ascaris lumbricoides is the largest nematode intestinal parasite found in humans; females may reach lengths greater than 1 meter. A. lumbricoides is also very widespread, even in developed nations, although it is now a relatively uncommon problem in the United States. It may cause symptoms ranging from relatively mild (such as a cough and mild abdominal pain) to severe (such as intestinal blockage and impaired growth). Of all nematode infections in the United States, pinworm (caused by Enterobius vermicularis) is the most common. Pinworm causes sleeplessness and itching around the anus, where the female worms lay their eggs during the night.

 This phylum is composed of organisms with the following characteristics: Thin and elongated (hair-like)
Tubular in appearance
Majority are microscopic while a few can be viewed with the naked eye. However, Placentonema gigantissima, a nematode that infects sperm whales has been shown to grow up to 9 meters (30 ft) in length
Head and tail are not visually distinct
They have a cuticle
They have a nervous system that controls the muscle cells
Classes of Phylum Nematoda
Nematodes are further divided into three major classes and subclasses that possess several different characteristics including: Class Rhabditea
Ancylostoma caninum attached to the intestinal mucosa,Source: CDC's [http://phil.cdc.gov/phil/home.asp Public Health Image Library] Image #5205 |Source=Originally from [http://en.wikipedia.org
Class Rhabditea is composed of both parasitic and free-living nematodes. However, the majority of nematodes that exist as parasites are found in this class. Parasitic Rhabditea
Parasitic nematodes found in class Rhabditea include Ascaris, Enterobius (e.g. human pinworm), Necator species as well as Wuchereria species. These species infect and cause a variety of diseases in human beings ranging from minor to very serious conditions. For instance, Wuchereria bancrofti, a species belonging to the genus Wuchereria causes a serious condition known as Lymphatic filariasis characterized by the swelling of arms and legs. This is a serious condition that is not only painful, but also causes the disfiguration of arms and/or legs.

Species

The pinworm ( species Enterobius vermicularis ), also known as threadworm (in the United Kingdom and Australia) or seatworm, is a parasitic worm. It is a nematode (roundworm) and a common intestinal parasite or helminth, especially in humans. The medical condition associated with pinworm infestation is known as pinworm infection ( enterobiasis) (a type of helminthiasis) or less precisely as oxyuriasis in reference to the family Oxyuridae. Other than human, Enterobius vermicularis were reported from bonnet macaque. Other species seen in primates include Enterobius buckleyi in Orangutan and Enterobius anthropopitheci in chimpanzee.

 The nervous system consists of a nerve ring and many longitudinal nerve cords. Reproduction is exclusively sexual, and males are usually shorter than females. Defense mechanism
As part of the parasite defense strategy, Ascaris roundworms secrete a series of inhibitors to target digestive and immune-related host proteases, which include pepsin, trypsin, chymotrypsin / elastase, cathepsins, and metallocarboxypeptidases (MCPs). Ascaris species inhibit MCPs by releasing an enzyme known as Ascaris carboxypeptidase inhibitor (ACI). This enzyme binds to the active site of MCP and blocks the cleavage of its own proteins by the host MCP. Similarly, they inhibit trypsin by releasing the protein Ascaris Trypsin Inhibitor (pdb 1ATA, https://www.rcsb.org/structure/1ATA 1ATB)
Evolution
Ascaris has been present in humans for at least several thousand years, as evidenced by Ascaris eggs found in paleofeces and in the intestines of mummified humans. History
A. lumbricoides was originally called Lumbricus teres and was first described in detail by Edward Tyson in 1683. The genus Ascaris was originally described as the genus for Ascaris lumbricoides by Carl Linnaeus in 1758. The morphologically similar Ascaris suum was described from pigs by Johann August Ephraim Goeze in 1782. Gallery

The Aschelminthes (also known as Aeschelminthes, Nemathelminthes, Nematodes ), closely associated with the Platyhelminthes, are an obsolete phylum of pseudocoelomate and other similar animals that are no longer considered closely related and have been promoted to phyla in their own right. The term Aschelminth is now generally only used as an informal name for any member of the approximately ten different invertebrate phyla formerly included within Aschelminthes. It is a polyphyletic group. Subdivisions
Although invertebrate experts do not necessarily agree on these categorizations, groups that are generally incorporated into Aschelminthes include: Acanthocephala
Chaetognatha

about the Phylum and their Digestive System
Phylum Platyhelminthes consists of many worms including the most well-known flatworm. From the name, all species in the phylum Platyhelminthes are flat and thin. There are many kinds of flatworms, because that is only a broad range of animals. Flatworms include Planaria, which are found in the class turbellaria, and there are also tapeworms under the class Cestoda. Platyhelminthes animals are symmetrical on the right and left side on their body. Their structures and everything from the epidermis to the intestine and nervous system. The digestive system of Platyhelminthes isn't very complicated, in fact it really is not a full system but rather a digestive tract. Compared to the more complex human body as you may know it, the digestive system is quite simple.

 However, the parasitic species often have limited digestive tracts, nervous systems, and locomotor abilities. Parasitic forms may have complex reproductive cycles with several different life stages and more than one type of host. Some are monoecious, having both male and female reproductive organs in a single individual, while others are dioecious, each having either male or female reproductive organs. Nematoda (Roundworms)
Figure 1. A micrograph of the nematode Enterobius vermicularis, also known as the pinworm. ( credit: modification of work by Centers for Disease Control and Prevention)
Phylum Nematoda (the roundworms) is a diverse group containing more than 15,000 species, of which several are important human parasites (Figure 1). These unsegmented worms have a full digestive system even when parasitic. Some are common intestinal parasites, and their eggs can sometimes be identified in feces or around the anus of infected individuals. Ascaris lumbricoides is the largest nematode intestinal parasite found in humans;

vector-borne transmission of larval stages taken up by blood-sucking arthropods or undergoing amplification in aquatic molluscs (e.g. Onchocerca microfilariae ingested by blackflies and injected into new human hosts, Schistosoma eggs release miracidia to infect snails where they multiply and form cercariae which are released to infect new hosts). >
predator-prey transmission of encysted larvae within prey animals (vertebrate or invertebrate) being eaten by predators where adult worms develop and produce eggs (e.g. Dracunculus larvae in copepods ingested by humans leading to guinea worm infection, Taenia cysticerci in beef and pork being eaten by humans, Echinococcus hydatid cysts in offal being eaten by dogs). Taxonomic overview
Two classes of nematodes are recognized on the basis of the presence or absence of special chemoreceptors known as phasmids: Secernentea (Phasmidea) and Adenophorea (Aphasmidea). While many different orders are recognized within these classes, the main parasitic assemblages infecting humans and domestic animals include one aphasmid order (Trichocephalida) and 6 phasmid orders (Oxyurida, Ascaridida, Strongylida, Rhabditida, Camallanida, and Spirurida). >
trichocephalid ‘whip-worms’ have long thin anterior ends which they embed in the intestinal mucosa of their hosts. They have simple life-cycles where infections are acquired by the ingestion of eggs and emergent larvae moult and mature to adults in the gut. Trichuris infections in humans may cause inflammation, tenesmus, straining and rectal prolapse. >
oxyurid ‘pin-worms’ have small thin bodies with blunt anterior ends. They have simple life-cycles, but with an unusual modification.

Gordon Ramel
 Fertilisation is internal and females lay eggs over a prolonged time period. Thus a female Ascaris lumbricoides may lay her eggs at the rate of 200,000 per day and have had a total 27 million eggs within her at the start of her reproductive career. Young nematodes hatch from these eggs and go through 4 moults before they become adults. Nematoda Classification

Helminths are a group of organisms which share a similar form but are not necessarily related as part of evolution. The term "helminth" is an artificial term. There is no real consensus on the taxonomy (or groupings) of the helminths, particularly within the nematodes. The term "helminth" contains a number of phyla, many of which are completely unrelated. However, for practical considerations the term is currently used to describe four phyla with superficial similarities:

 While A. suum generally infects pigs, they can infect humans as well. Ascaris are soil-transmitted helminths that infect via the consumption of contaminated soil or foods grown in soil contaminated with Ascaris eggs and belong to the Phylum Nematoda , the phyla designation of all roundworms. Nematodes are pseudocoelomates, ('fake' coelomates), meaning that their fluid filled cavity isn't encased in mesoderm and makes direct contact with their intestinal wall. Ascariasis infections currently affect some 1-2 billion people, with the greatest population being sub-Saharan Africa, Latin America, and Asia. Symptoms include: bowel distention, passing worms and/or eggs, fever, nausea, weight loss, intestinal ulcers, vomiting worms and/or coughing, and secondary tissue damage from excessive coughing and eosinophilia.

You read that right, in this lesson we will talk about parasitic worms, specifically a genus called Ascaris. So we’ve all heard the term ‘parasite’, but what does it actually mean? Well, a parasite is an organism that feeds off of or lives within another organism, called a host, to the detriment of that host organism.

There is a general consensus concerning the classes Turbellaria and Cestoda, however the Monogenea, Digenea and the Aspidobothrians are somewhat confusing.

Recall, pseudocoelomates differ from coelomates in that their body cavities are not completely lined by mesoderm-derived tissue. Figure. 2 (Click image to enlarge)
Pseudocoelomates: The Phylum Nematoda
Roundworms are pseudocoelomates that belong to the phylum Nematoda. This extremely diverse phylum includes some highly beneficial soil worms, as well as some notorious pests and parasites. The highly pressurized pseudocoelom of these animals can function as a hydrostatic skeleton, which can be useful in drilling through soil or a host's body tissue. Annelids, cnidarians, and flatworms also have hydrostatic skeletons. Figure. 2 (Click image to enlarge)
Giant kidney worms are able to parasitize many mammals, including humans.

Species

The pinworm ( species Enterobius vermicularis ), also known as threadworm (in the United Kingdom and Australia) or seatworm, is a parasitic worm. It is a nematode (roundworm) and a common intestinal parasite or helminth, especially in humans. The medical condition associated with pinworm infestation is known as pinworm infection ( enterobiasis) (a type of helminthiasis) or less precisely as oxyuriasis in reference to the family Oxyuridae. Other than human, Enterobius vermicularis were reported from bonnet macaque. Other species seen in primates include Enterobius buckleyi in Orangutan and Enterobius anthropopitheci in chimpanzee.

Ascaris – Definition, Anatomy, Significance
Ascaris is a genus of a parasitic roundworm that belongs to the phylum Nematoda. Generally, this genus is known as intestinal roundworms. Out of that, Ascaris lumbricoides, one species of Ascaris is the most common human parasite. It causes a disease called ascariasis. Significantly, Ascaris is a good example of worms with clearly visible sexual dimorphism. Here, the female individuals have a significantly longer and heavier body than their male counterpart.

about the Phylum and their Digestive System
Phylum Platyhelminthes consists of many worms including the most well-known flatworm. From the name, all species in the phylum Platyhelminthes are flat and thin. There are many kinds of flatworms, because that is only a broad range of animals. Flatworms include Planaria, which are found in the class turbellaria, and there are also tapeworms under the class Cestoda. Platyhelminthes animals are symmetrical on the right and left side on their body. Their structures and everything from the epidermis to the intestine and nervous system. The digestive system of Platyhelminthes isn't very complicated, in fact it really is not a full system but rather a digestive tract. Compared to the more complex human body as you may know it, the digestive system is quite simple.

 Now, since we are specifically talking about parasitic worms, rather than, say flies (such as mosquitos), fish (such as the toothpick fish), or insects (like a flea or tick), we can use the term helminth, which specifically refers to parasitic worms. Ascaris lumbricoides, giant intestinal worms

Classification in Phylum Nematoda
So, we’ve established that Ascaris is a genus of helminth. They belong to the Kingdom Animalia (just like us), and the Phylum Nematoda (from the Greek ‘nematos’ meaning ‘thread’). Nematoda is the phylum containing all roundworm species. But, in spite of the fact that nematodes are ’roundworms’, that does not mean that all worms that are round in shape are nematodes. The term nematoda actually refers, not to their body shape, but to their digestive tract, which is tube-like with tapered openings at either end. Nematodes are pseudocoelomates, meaning they have a ‘fake’ coelom. A coelom is a body cavity that surrounds the digestive track. In nematodes, their pseudocoelom, or fluid filled cavity, isn’t encased in mesoderm but makes direct contact with their intestinal wall. Cross-section of coelomate and pseudocoelomate

What should also be noted is that not all nematodes are parasitic, although, of the approximately 12,000 known species (some estimate that there may be as many 500,000 species because so little is known of their diversity), about half are of the parasitic persuasion.

For instance, some of the nematodes that live on land play an important role in decomposition while others act as predators of various microorganisms. Phylum Platyhelminths
The phylum Platyhelminth is composed of flatworms that are more flattened in shape compared to other worms. The phylum is divided into the following classes: Catenulida - This is a small group that consists of about 100 species that have been identified so far.

 Infective eggs are ingested (4), enter the gut (5), develop into larvae in the intestine, and penetrate the blood vessel to enter lungs, where they develop further (6), after 10 to 14 days, penetrate the alveolar walls, ascend the bronchial tree to the throat, and are re-swallowed (7). Upon reaching the small intestine, they develop into adult worms (8). It takes 2 to 3 months for one complete cycle. Adult worms can live 1 to 2 years.

 This is comprised of a circum-pharyngeal nerve ring made up from 4 nerve ganglia, from which 6 longitudinal nerves extend down through the body to the various parts of the gut and the reproductive organs. There are also 6 shorter nerves which extend forwards from the circum-pharyngeal ganglia towards the mouth. Nematodes have no circulatory or respiratory organs and the excretion of metabolic waste is via two simple ducts, or tubules, which have no nephridia or flame cells. Nematodes are copiously reproductive and most of their body cavity, which is a pseudocoelom, is filled with paired sets of reproductive organs – either ovaries or testes. Males and females copulate and the male introduces sperm to the females vagina – with the help of 2 stiff, horny spicules that are a part of his cloaca. Fertilisation is internal and females lay eggs over a prolonged time period. Thus a female Ascaris lumbricoides may lay her eggs at the rate of 200,000 per day and have had a total 27 million eggs within her at the start of her reproductive career. Young nematodes hatch from these eggs and go through 4 moults before they become adults. Nematoda Classification

Coelomates and Pseudocoelomates
The figure on the right illustrates the three basic body plans encountered in the bilateria: the acoelomates (e.g., flatworms, flukes, and tapeworms), the pseudocoelomates (e.g., roundworms, pinworms, and hookworms), and the coelomates (e.g., snails, clams, octopuses, earthworms, and leeches). Recall, pseudocoelomates differ from coelomates in that their body cavities are not completely lined by mesoderm-derived tissue. Figure. 2 (Click image to enlarge)

 Similarly, they inhibit trypsin by releasing the protein Ascaris Trypsin Inhibitor (pdb 1ATA, https://www.rcsb.org/structure/1ATA 1ATB)
Evolution
Ascaris has been present in humans for at least several thousand years, as evidenced by Ascaris eggs found in paleofeces and in the intestines of mummified humans. History
A. lumbricoides was originally called Lumbricus teres and was first described in detail by Edward Tyson in 1683. The genus Ascaris was originally described as the genus for Ascaris lumbricoides by Carl Linnaeus in 1758. The morphologically similar Ascaris suum was described from pigs by Johann August Ephraim Goeze in 1782. Gallery

Bilateral Symmetry and Body Plans
All bilaterally symmetrical animals developed from 3 embryonic cell layers: Ectoderm
Endoderm
Mesoderm
3 types- Acoelomates,
Pseudocoelomates
, Coelomates
Acoelomates
Develop from the 3 layers but have no body cavities
Digestive tract extends throughout body
May have been first group of animals to evolve
Ex. Flatworms

Parasitic nematodes often contain specific body structures which promote parasitic behaviors such as ridges, rings or bristles that allow for attachment. Two major types of roundworms that commonly infect humans include Ascaris and Enterobious. Ascariasis is a disease that is caused by the parasitic roundworm Ascaris lumbricoides and is transmitted by ingesting food contaminated with Ascaris eggs. Enterobius, referred to as pinworm, causes enterobiasis and is commonly found in the intestine of children. The entire life cycle of the pinworm occurs within the human gastrointestinal tract.

 Platyhelminths, or flatworms, include both free-living and parasitic species. The phylum Platyhelminthes is divided into two monophyletic clades, the Catenulida (with just around 100 known species; Larsson and Jondelius 2008) and the Rhabditophora, which includes nearly all known platyhelminths (Timothy et al. 2004; Willems et al. 2006; Larsson and Jondelius 2008). The majority of flatworms are obligately parasitic, either flukes (members of the classes Trematoda and Monogenea, such as the Schistosoma trematodes that cause schistosomiasis) or tapeworms (members of the class Cestoda, such as the Beef Tapeworm) (Brusca and Brusca 2003). These obligately parasitic groups together form a monophyletic clade known as Neodermata. Many of these parasitic flatworms have complex life cycles involving multiple hosts.

The three commonly studied and well-known groups include the intestinal Nematodes (round worms), tapeworms (Cestodes), and blood, tissue and organ flukes (Trematodes). Intestinal helminths are commonly transmitted through fecally contaminated food and water and these parasites include Ascaris lumbricoides, Trichuris trichiura (whipworm), and Enterobius vermicularis (pin worm). Hookworms include Ancylostoma duodenale and Necator americanus, whose larvae penetrate the skin after their ova have been passed in human feces. These soil-transmitted helminths are associated with climates that are warm and moist and where sanitation and hygiene are poor. The eggs are passed in the feces of the infected individual, the larvae hatch, contaminate the soil, and can penetrate the skin when contact is made. Hookworms: An image of a hookworm attached to intestinal mucosa. Ascaris lumbricoides, the cause of Ascariasis, is a type of soil transmitted helminth. Ascaris, the largest roundworm, lives in the intestine and the eggs are passed in the feces of the infected person.

 Ascaris lumbricoides
Helminths are a group of organisms which share a similar form but are not necessarily related as part of evolution. The term "helminth" is an artificial term. There is no real consensus on the taxonomy (or groupings) of the helminths, particularly within the nematodes. The term "helminth" contains a number of phyla, many of which are completely unrelated. However, for practical considerations the term is currently used to describe four phyla with superficial similarities: Annelida (ringed or segmented worms), Platyhelminthes ( flatworms ), Nematoda (roundworms), and Acanthocephala (thorny-headed worms). The phylum Platyhelminthes includes two classes of worms of particular medical significance: the cestodes (tapeworms) and the trematodes (flukes and blood flukes ), depending on whether or not they have segmented bodies. There may be as many as 300,000 species of parasites affecting vertebrates, and as many as 300 affecting humans alone. Helminths of importance in the sanitation field are the human parasites, and are classified as Nemathelminthes (nematodes) and Platyhelminthes, depending on whether they possess a round or flattened body, respectively.

Is a worm considered an insect? If not, what is it? - Quora Is a worm considered an insect? If not, what is it?
Is a worm considered an insect? If not, what is it? Those are: Nematoda ( roundworms ), Echiura ( spoon worms ), Entoprocta, Gnathostomulida ( jaw worms ), Hemichordata, Acanthocephala ( thorny-headed worms ), Chaetognatha ( arrow worms ), Plathelminthes ( flatworms ), Priapulida ( priapulid worms ), Annelida ( ringed worms ), Nematomorpha ( horsehair worms ), Sipunculida ( sipunculid worms) and Nemertini ( ribbon worms ). Insects (together with crustaceans, myriapods and arachnids) belong to phylum Euarthropoda, so no worms in this group. The probably best known worms, earth worms, are of phylum Annelida (ringed worms). Nematodes often live as parasites or predators. Together with flatworms they comprise some major human parasites. But many such as Sipunculid worms are typically unknown to most people, in their case mostly because they dwell in sub-marine mud and rocks. So this shows how diverse in origin and internal structure animals can be, even if their external shape makes them appear similar (such as ‘worms’). Phylum - Wikipedia

 Parasitic forms may have complex reproductive cycles with several different life stages and more than one type of host. Some are monoecious, having both male and female reproductive organs in a single individual, while others are dioecious, each having either male or female reproductive organs. Nematoda (Roundworms)
Phylum Nematoda (the roundworms) is a diverse group containing more than 15,000 species, of which several are important human parasites (Figure 5.2. 1 ). These unsegmented worms have a full digestive system even when parasitic. Some are common intestinal parasites, and their eggs can sometimes be identified in feces or around the anus of infected individuals. Ascaris lumbricoides is the largest nematode intestinal parasite found in humans; females may reach lengths greater than 1 meter. A. lumbricoides is also very widespread, even in developed nations, although it is now a relatively uncommon problem in the United States. It may cause symptoms ranging from relatively mild (such as a cough and mild abdominal pain) to severe (such as intestinal blockage and impaired growth).

A. lumbricoides is also very widespread, even in developed nations, although it is now a relatively uncommon problem in the United States. It may cause symptoms ranging from relatively mild (such as a cough and mild abdominal pain) to severe (such as intestinal blockage and impaired growth).

 Wikipedia currently lists 34 animal phyla (the highest, most fundamentally different class), among which 14 contain worms (i.e. worm-shaped animals). Those are: Nematoda ( roundworms ), Echiura ( spoon worms ), Entoprocta, Gnathostomulida ( jaw worms ), Hemichordata, Acanthocephala ( thorny-headed worms ), Chaetognatha ( arrow worms ), Plathelminthes ( flatworms ), Priapulida ( priapulid worms ), Annelida ( ringed worms ), Nematomorpha ( horsehair worms ), Sipunculida ( sipunculid worms) and Nemertini ( ribbon worms ). Insects (together with crustaceans, myriapods and arachnids) belong to phylum Euarthropoda, so no worms in this group. The probably best known worms, earth worms, are of phylum Annelida (ringed worms). Nematodes often live as parasites or predators. Together with flatworms they comprise some major human parasites. But many such as Sipunculid worms are typically unknown to most people, in their case mostly because they dwell in sub-marine mud and rocks. So this shows how diverse in origin and internal structure animals can be, even if their external shape makes them appear similar (such as ‘worms’). Phylum - Wikipedia

 As a result, food material is taken in through the pharynx and ejected through the mouth. While a majority of species in this class are predators of smaller invertebrates, others live as herbivores, scavengers, and ectoparasites. Pigment cells and photoreceptors present in their eyespots is used in place of image-forming eyes. Depending on the species, the peripheral nervous system of Turbellarians ranges from very simple to complex interlacing nerve webs that control muscle movement. Reproduction is achieved through a number of methods that include sexual reproduction (simultaneous hermaphrodites) and asexual reproduction (transverse fission). In sexual reproduction, eggs are produced and bundled into cocoons from which juveniles hatch and develop. Asexually, some of the species split into two halves that the regenerate to form the missing half thus developing into a whole organism. Common orders belonging to class Turbellaria include: Order Acoela - About 600 species found in marine environments
Order Neorhabdocoela - About 600 species characterized by a saclike intestine, two longitudinal trunks, and a nervous system
Order Catenulida - Consists of about 70 species found in freshwater
Order Macrostomida - 200 species often found between sand grains
Some of the other orders include: Tricladida
Proseriata
Polycladida
Lecithoepitheliata
Kalyptorhynchia

 The eggs are found in soil for many years because they are very resistant to environmental conditions. Pathology of infections of A. lumbricoides can occur from either migration of the larvae though the lungs or from the adult worms in the intestine. Many people who are infected are asymptomatic, and pathology depends on the amount of worms. Heavy infections of Ascaris can lead to serious conditions, such as intestinal obstruction. Ascaris lumbricoides infection is typically diagnosed by microscopically finding the characteristic eggs in feces. According to the Global Network in 2010, more than 807 million people worldwide are infected with the giant intestinal roundworm, Ascaris lumbricoides.

2. Human pinworm (Enterobius vermicularis)
3. Ascaris
4. Hookworms (Necator americanus and Ancylostoma duodenale)
5. Intestinal Trematodes
6. Entamoeba histolytica
 The pinworm is diagnosed by checking for ova and the female pinworm in perianal swabs through a microscope. The sample needs to be taken in the morning. Anthelmintic drugs such as albendazole, mebendazole, and pyrantel pamoate can be used for treatment. 3. Ascaris
Ascariasis has been known to be the world’s most common parasitic worm infection. The Ascaris lumbricoides is a worm that grows to up to 35 centimeters long, and it is the biggest roundworm that lives in the human body. The parasite can stay in a person’s small intestines for as long two years if it is not treated. One female Ascaris lumbricoides can lay approximately 200,000 eggs in the soil, and their life cycle involves different organs that include the lungs and the liver. An infected person is asymptomatic, but in a few cases, individuals may develop malnutrition, stunted growth, hepatobiliary injury, pneumonia, and eosinophilia. 4.

Nematode
animal
 Some species possess a pseudocoel, a fluid-filled body cavity between the digestive tract and the body wall. Like arthropods and members of six other phyla, nematodes secrete an external cuticle that is periodically molted. These animals have been provisionally grouped together as the Ecdysozoa, a taxonomic category based on the assumption that molting has evolved only once. So far, gene sequence data from several molecules support such an assumption. The nematode Ascaris lumbricoides is a multicellular organism. Javier Palaus Soler/Ostman Agency
The sexes are separate in most species, but some are hermaphroditic (i.e., have both male and female reproductive organs in the same individual). Nematodes range in size from microscopic to 7 metres (about 23 feet) long, the largest being the parasitic forms found in whales. Nematode parasites of animals occur in almost all organs of the body, but the most common sites are in the alimentary, circulatory, and respiratory systems. Some of these worms are known by such common names as hookworm, lungworm, pinworm, threadworm, whipworm, and eelworm. Nematodes can cause a variety of diseases (such as filariasis, ascariasis, and trichinosis) and parasitize many crop plants and domesticated animals.

 Reproduction
Additionally, ascaris can be either male or female while earthworm is a hermaphrodite. Importance
Ascaris can cause diseases to animals and plants while earthworm changes the physical structure of the soil. Conclusion
Ascaris is a roundworm that belongs to the phylum Nematoda. It has a thin, unsegmented body and it is a parasitic worm. It also has a pseudocoelom. Generally, Ascaris causes diseases in their host. In contrast, earthworm is a segmented worm that lives freely in the environment. It is important in agricultural fields as it changes the physical structure of the soil in such a way to increase crop growth. However, the main difference between Ascaris and earthworm is their anatomy and importance. References:

Ascaris, any of a genus of worms (order Ascaridida, class Secernentea) that are parasitic in the intestines of various terrestrial mammals, chiefly herbivores. They are typically large worms (up to about 40 cm long) characterized by a mouth surrounded by three lips. The species Ascaris lumbricoides is probably the most familiar parasite in humans. More than 25 percent of the world’s human population is infected with these worms, and about 20,000 people die of Ascaris infestation yearly. An almost identical worm, often called A. suum, occurs in pigs. It is, however, not certain that this species is distinct from the one that infests humans. See ascariasis. Ascaris

Kingdom Animalia
 Phylum nematoda consists of only roundworms, some that are parasitic. Roundworms and their parasitic freinds are psuedococelomates,  which means they have a psuedocelum, a space between the internal digestive organs and the outer dermis of the worm. They  have a complete, one-way digestive tract. Major Classes: Hookworms: Burrow into your skin, travel through your bloodstream to your lungs, then are coughed back up and swallowed  into your digestive system. Pinworms: Live in your lower intestine and lay their eggs in your rectum. Trichinella: Flu like worm.

Carolina Noreña, ... Francisco Brusa, in Thorp and Covich's Freshwater Invertebrates (Fourth Edition), 2016
Introduction
The flatworms of the phylum Platyhelminthes comprise free-living (“Turbellaria”) and obligate parasitic organisms (Monogenea, Digenea, Aspidogastrea, and Cestoda, today grouped in Neodermata). “ Turbellaria” includes an amazing variety of forms, but built in a similar way. All have the following characteristics: bilateral symmetry, organs embedded in a solid cellular matrix (the parenchyma), a sac-like gut without an anus, a nervous system with an anterior “brain” and lateral nerve chords, and internal fluids that are regulated by protonephridia. Most are cross-fertilizing hermaphrodites, with morphologically diverse structures like sclerotic parts of the male copulatory organ that forms stylets of different shape and complexity, and with endolecithal or ectolecithal eggs. Variation also can be found in the location and shape of the pharynx along the main body-axis. Most “Turbellaria” are small with a body size of around 1 mm (microturbellaria), but others, such as Tricladida and Polycladida, have a body-size of 5–10 cm (macroturbellaria). They show a worldwide distribution and inhabit most kinds of freshwater, brackish, and marine habitats. Based on their simple body structure, the “Turbellaria” has been considered one of the most basal bilateria ( Littlewood & Bray, 2001 ). This hypothesis is supported by the results obtained from molecular phylogenetic analysis ( Ruiz-Trillo et al.,

The pinworm (genus Enterobius) is a type of roundworm (nematode), and three species of pinworm have been identified with certainty. Humans are hosts only to Enterobius vermicularis (formerly Oxyurias vermicularis ). Chimpanzees are host to Enterobius anthropopitheci, which is morphologically distinguishable from the human pinworm. Hugot (1983) claims another species affects humans, Enterobius gregorii, which is supposedly a sister species of E. vermicularis, and has a slightly smaller spicule (i.e., sexual organ). Its existence is controversial, however; Totkova et al. ( 2003) consider the evidence to be insufficient, and Hasegawa et al. ( 2006) contend that E. gregorii is a younger stage of E. vermicularis. Regardless of its status as a distinct species, E. gregorii is considered clinically identical to E. vermicularis. Morphology

 Ascaris lumbricoides
Ascaris is a genus of parasitic nematode worms known as the "small intestinal roundworms", which is a type of parasitic worm. One species, Ascaris lumbricoides, affects humans and causes the disease ascariasis. Another species, Ascaris suum, typically infects pigs. Parascaris equorum, the equine roundworm, is also commonly called an "Ascarid". Their eggs are deposited in feces and soil. Plants with the eggs on them infect any organism that consumes them. A. lumbricoides is the largest intestinal roundworm and is the most common helminth infection of humans worldwide. Infestation can cause morbidity by compromising nutritional status, affecting cognitive processes, inducing tissue reactions such as granuloma to larval stages, and by causing intestinal obstruction, which can be fatal.

 Members of the clade or class Rhabditophora are now dispersed among multiple orders of Platyhelminthes, the most familiar of these being the Polycladida, which contains the large marine flatworms; the Tricladida (which includes Dugesia [“planaria”] and Planaria and its relatives); and the major parasitic orders: Monogenea (fish ectoparasites), Trematoda (flukes), and Cestoda (tapeworms), which together form a monophyletic clade. Traditional flatworm classes. Phylum Platyhelminthes was previously divided into four classes. ( a) Class Turbellaria includes the free-living polycladid Bedford’s flatworm ( Pseudobiceros bedfordi ), which is about 8 to 10 cm in length. ( b) The parasitic class Monogenea includes Dactylogyrus spp, commonly called gill flukes, which are about 0.2 mm in length and have two anchors, indicated by arrows used to attach the parasite on to the gills of host fish. ( c) The class Trematoda includes Fascioloides magna (right) and Fasciola hepatica (two specimens on left, also known as the common liver fluke). ( d) Class Cestoda includes tapeworms such as this Taenia sa
