Gastroenteritis small intestine

Staphylococcus aureus is known for its ability to produce a variety of toxins and many disease syndromes. One of the most frequently observed diseases is staphylococcal tonsillitis. These bacteria are frequently present on tonsils of healthy carriers. Patients that are affected by tonsillitis swallow staphylococci hidden in tonsil crypts. However, in this case staphylococci do not cause any gastrointestinal symptoms in the host organism, even if they enter the gastrointestinal tract. The barrier of gastric juice and conditions in a small intestine inhibit the outgrowth of staphylococci and toxin production -gastroenteritis is caused solely by a toxin produced outside the host organism. 

When substantial carbohydrate maldigestion occurs in infants, it can lead to diarrhea. This is most often seen when the infant has experienced some other insult that has damaged the small intestine enterocytes, producing a secondary hypolactasia.This is more so when the infant has a rotavirus infection, and rotavirus is the most important cause of gastroenteritis in infancy. Rotavirus infects only mature enterocytes,... 

It is characterised by a selective eosinophilic infiltration of the stomach and/or small intestine. Primary eosinophilic gastroenteritis includes multiple disease entities depending on the level of histological involvement, and may be mucosal, muscular or serosal (Lee et al. 1993). 

The remaining 59 patients, with relatively low serum bile acid concentrations (SGLC = 2.2 0.3,GC = 2.2 0.3, 3a-hydroxy bile acids = 10.3 0.9), included patients with mild liver disease, intestinal dysfunctions such as Crohn s disease, coeliac disease and gastroenteritis, acute lymphatic leukemia treated with methotrexate, contaminated small bowel syndrome and three patients with benign recurrent intrahepatic cholestasis (BRIC).
