Acute enteritis is the most common intestinal disease. The main symptoms are abdominal pain, diarrhea, watery stools, less than a few times a day, more than a dozen, or even more, on human health. Salmonella spp. are the main pathogens of acute gastroenteritis in bow J, including Salmonella typhimurium, Salmonella enterica, Salmonella cholerae, Salmonella chicken, Salmonella duck are more common. These bacteria are widely present in the intestinal tract of various animals, such as pigs, cattle, sheep, dogs, chickens, ducks and rodents, and when animals are sick, these genera can invade their bloodstream, internal organs and muscle tissue, and eggs are often contaminated by such bacteria. These bacteria through contact with the pathogenic bacteria of the utensils, hands, etc. and then contact cooked food and cold dishes, etc.; will multiply on it, and produce a lot of endotoxin, people eat this food, due to the role of bacteria and endotoxin, stimulate the gastrointestinal mucosa, causing congestion of the mucosa, edema, increased secretion of intestinal fluid, resulting in a violent gastrointestinal reaction. Bacteria and toxins into the blood, but also can cause bacteremia and toxemia.

The pathogenic bacteria that cause acute gastroenteritis are also Aspergillus, pathogenic E. coli, etc. Fungi can also cause acute gastroenteritis, but it is relatively rare. Staphylococcus aureus, if contaminated with dairy products, eggs and meat, can multiply in the right environment and produce heat-resistant enterotoxins, causing morbidity.
