Multiple Duodenal Erosions due to Salmonella Enteritis (3 of 5)

Nontyphoidal Salmonellosis Prognosis of patients with simple gastroenteritis is excellent except for very young infants or patients with debilitating diseases. The prognosis for Salmonella meningitis or endocarditis is poor. Salmonella infection most commonly begins with ingestion of bacteria in contaminated food or water. However, direct contact with animal and human carriers has also been implicated. Reptile and amphibian carriers are the most commonly recognized sources of direct contact Studies involving healthy human volunteers required a median dose of 1 million bacteria to produce disease. However, point outbreaks suggest as few as 200 bacteria may produce nontyphoid gastroenteritis.
