Abstract
A 42-year-old woman was admitted to a local hospital on Februrary 26, 1985, with the sudden onset of watery diarrhea, hematochezia, abdominal pain and high grade fever. For three days before admission, she was prescribed AB-PC 2g by a practitioner because of lumbago. Sigmoidoscopy on that day of admission disclosed reddish edematous mucosa, and narrowed lumen of the sigmoid colon and descending colon, and normal mucosa in the rectum. Barium enema following the sigmoidoscopy showed thumb printing and narrowed lumen from descending colon to transverse colon. At that time, antibiotics-associated colitis was most likely. Later, the diagnosis of salmonella infection of the colon was made by cultures of a stool sample which was recognized colonies of salmonella typhimurium. Subjective symtoms completely disappeared 40 days after admission. Thus, when colitis occured during the treatment of antibiotics. salmonella infection of the colon should be considered in addition to antibiotics associated colitis.
