A Case of Salmonella paratyphi Infection Manifested as Duodenal and Terminal Ileal Ulcers / 대한소화기내시경학회지

ABSTRACT

Infection due to Salmonella typhi and Salmonella paratyphi is called enteric fever which is manifested by fever, abdominal pain, and intermittently other gastrointestinal symptoms like vomiting and diarrhea. Although Salmonella species may invade any site of the gastrointestinal tract, it usually invades terminal ileum. The pathologic manifestation of salmonellosis may vary from nonspecific mucosal change (erythema, edema, ulceration etc.) of invaded site to intestinal perforation or hemorrhage. However, the report of upper gastrointestinal invasion by Salmonella species is rare, and confirmation by tissue culture is difficult because gastric acid and the normal propulsive peristaltic flow of the small bowel help to limit the bacterial populations of the upper gastrointestinal tract. We report here a case of Salmonella paratyphi infection proven by tissue culture in a 26-year-old man who presented with fever and watery diarrhea and was found to have multiple duodenal and terminal ileal ulcers.
