[Yersinia and infantile gastroenteritis].

Abstract

Fecal samples and intestinal mucosal biopsies of 16 patients in paediatric age, with protracted diarrhoea with blood and mucus, were examined for intestinal pathogens including Yersinia. Yersinia enterocolitica 1/5/XZ and Yersinia intermedia 1/18/XZ were isolated from fecal samples of two patients. In another child, Yersinia enterocolitica, 1/5/XZ was isolated from fecal sample, while Yersinia enterocolitica 1/self-agglutinable/XZ from colon biopsy. The other intestinal pathogens were absent; Aeromonas hydrophila however was isolated from two fecal samples. The Yersinia strains isolated are not frequently found in human infections.
