Attaching and effacing bacteria in the intestines of calves and cats with diarrhea.
Histopathologic and electron microscopic examination of intestines of three calves and two cats revealed attaching effacing bacteria characteristic of enteropathogenic Escherichia coli (EPEC) in ileum, cecum, and colon. The attaching effacing bacteria in one of the calves contained bacteriophages, and an E. coli isolate from that calf was shown to produce Shiga-like toxin. These findings contribute to emerging evidence that attaching effacing intestinal bacteria are globally distributed pathogens in a variety of host species and that bacteriophage-mediated production of Shiga-like toxin is related to the virulence of such bacteria.
