Bacterial gastroenteritis
Bacterial gastroenteritis is an inflammation of the stomach and intestines caused by bacteria or bacterial toxins. Additional recommended knowledge
CausesMany different types of bacteria can produce the symptoms associated with bacterial gastroenteritis, including salmonella, shigella, staphylococcus, Campylobacter jejuni, clostridium, E. coli, yersinia, and others. Some sources of the infection are improperly prepared food, reheated meat dishes, seafood, dairy, and bakery products. Each organism causes slightly different symptoms but all result in diarrhea. Colitis, inflammation of the large intestine, may also be present. Risk factors are consumption of improperly prepared foods or contaminated water and travel or residence in areas of poor sanitation. The incidence is 1 in 1,000 people. SymptomsSigns and Tests
This disease may also alter the results of the following tests:
TreatmentThe objective of treatment is to replace fluids and electrolytes (salt and minerals) lost by diarrhea. Blood transfusions are rarely required. Antibiotic or antimicrobial therapy is usually not indicated unless the rest of the body is affected. Self-care measures to avoid dehydration include drinking electrolyte solutions to replace fluids lost by diarrhea, and eating no solid food until the diarrhea has passed. People with diarrhea, especially young children, who are unable to drink fluids due to nausea may need medical attention and intravenous fluids. People taking diuretics ("water pills") need to be cautious with diarrhea and may need to stop taking the medication during an acute episode, as directed by the health care provider. PrognosisWith most infections, symptoms improve with fluid and electrolyte replacement within a week. There are rare cases of patients with renal failure and even death due to the infection.
