Abstract
Adherence to HEp-2 tissue culture cells has been proposed as a virulence characteristic of enteropathogenic Escherichia coli (EPEC). A preliminary study revealed that E. coli that adhered to HEp-2 cells, but did not produce conventional enterotoxins and did not belong to recognized EPEC serogroups, could be isolated from adults from the United States who acquired diarrhea in Mexico. The purpose of this study was to determine the prevalence of these enteroadherent E. coli (EAEC) in 188 travelers with diarrhea and in 92 well travelers. EAEC were found in 14.9% of patients with diarrhea and in 7.6% of well individuals. Compared with well travelers, patients with diarrhea in whom no recognized enteropathogen could be identified had a 30.4% prevalence of EAEC (P less than .0003). These results further support our finding that EAEC are associated with diarrhea in travelers to Mexico and may help to explain the effect of antibiotics in the prevention and therapy for travelers' diarrhea in patients with no recognized bacterial enteropathogens.Entities:
