Important micro'organisms associating chronic or recurrent diarrhoea in adults

ABSTRACT

The study included 100 patients presenting with diarrhoea for more than two weeks. Stool examination included fresh microscopic and bacteriologic examination. Isolation of Enterobacteriaceae was confirmed by API 20 E system. Coli test sera were used for identification of enteropathogenic strains of E. coli [EPEC] and Salmonella test sera for salmonella. Special culture for Yersinia entercolitica was done. Cytopathic effect of C. difficile toxin [B] was also detected. The isolated pathogenic organisms included EPEC in [36%], non-typhoidal salmonellae [10%], Staphylococcus aureus [2%] and C. difficile [6%]. Four cases with Yersinia enterocolitica [4%] were isolated. This organism was mainly described in cold weather especially among pork consumers
