Staphylococcal enteritis is an inflammation that is usually caused by eating or drinking substances contaminated with staph enterotoxin. The toxin, not the bacterium, settles in the small intestine and cause inflammation and swelling. This in turn can cause abdominal pain, cramping, dehydration, diarrhea and fever. ''Staphylococcus aureus'' is a gram-positive, facultative anaerobe, coccal (round shaped) bacteria that appears in grape-like clusters that can thrive in high salt and low water activity habitats. ''S. aureus'' bacteria can live on the skin which is one of the primary modes of transmission. ''S. aureus'' can cause a range of illnesses from minor skin infections to Staphylococcus aureus food poisoning enteritis. Since humans are the primary source, cross-contamination is the most common way the microorganism is introduced into foods. Foods at high risks are those prepared in large quantities. Staphylococcus aureus is a true food poisoning organism. It produces a heat stable toxin enterotoxin when allowed to grow for several hours in foods such as cream-filled baked goods, poultry meat, gravies, eggs, meat salads, puddings and vegetables. It is important to note that the toxins may be present in dangerous amounts in foods that have no signs of spoilage, such as a bad smell, any off color, odor, or textural or flavor change. Enteritis is the inflammation of the small intestine. It is generally caused by eating or drinking substances that are contaminated with bacteria or viruses. The bacterium and/or toxin settles in the small intestine and cause inflammation and swelling. This in turn can cause abdominal pain, cramping, diarrhea, fever, and dehydration.〔 There are other types of enteritis, the types include: bacterial gastroenteritis, Campylobacter enteritis, ''E. coli'' enteritis, radiation enteritis, Salmonella enteritis and Shigella enteritis. == Pathogenesis== ''S. aureus'' is an enterotoxin producer. Enterotoxins are chromosomally encoded exotoxins that are produced and secreted from several bacterial organisms. It is a heat stable toxin and is resistant to digestive protease. It is the ingestion of the toxin that causes the inflammation and swelling of the intestine. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Staphylococcal enteritis」の詳細全文を読む スポンサード リンク
