| [ Summary ] | Salmonella is an important cause food-poisoning. Contaminated food raises the chances of infection. Hen eggs are the most important vehicle for this pathogen. There are increased risks of salmonellosis in patients with inflammatory bowel disease or HIV infection. The latent period is eight to forty-eight hours. Typical symptoms are diarrhea, abdominal pain, and high fever. Hematochezia or mucous containing feces are occassionally observed. Renal failure is a severe complication. Lesions may be distributed from the ileum to right side of the colon. Mucosal edema, redness, mucosal bleeding, irregular ulcers or longitudinal ulcers are often observed. Salmonella invades the gut mucosa and injures epithelial cells. Patchy or skipped distribution of lesions is a clue for differential diagnosis of ulcerative colitis. Fecal cultures are important for definite diagnosis. The use of antibiotics is not recommended in healthy hosts with mild to moderate symptoms. | |
