Gastroenteritis or infectious diarrhea is a medical condition from inflammation (-itis) of the gastrointestinal tract that involves both the stomach (gastro -) and the small intestine (entero -).It causes some combination of diarrhea, vomiting, and abdominal pain and cramping.iruses (particularly rotavirus) and the bacteria Escherichia coli and Campylobacter species are the primary causes of gastroenteritis. There are, however, many other infectious agents that can cause this syndrome. Non-infectious causes are seen on occasion, but they are less likely than a viral or bacterial cause.
Several different types of bacteria can cause inflammation of the small intestine in patients of all ages. Many cases are caused by accidentally consuming food that is contaminated with Salmonella, Escherichia coli, or listeria. A bacterium called Campylobacter jejuni is responsible for most serious cases of enteritis.cute cases of small intestine inflammation are almost always curable and short-lived. A doctor can look for the underlying causes of enteritis by screening blood samples for the presence of bacteria, viruses, medications, and different types of food-borne microorganisms.
