A bacterial pathogen was isolated from 47% of 328 expatriate patients with diarrhea seen at two medical clinics in Nepal in 1986. Enterotoxigenic Escherichia coli (24%), Shigella (14%), and Campylobacter species (9%) were isolated most frequently. Enteroinvasive and adherence factor-positive E coli were isolated from 2% and 1% of patients, respectively. ⋯ The isolation rates of bacterial pathogens decreased with length of stay in Nepal. A wide variety of enteropathogens were detected in travelers to Nepal, and Shigella and protozoa were particularly important. Length of time abroad and duration of symptoms were important diagnostic considerations.
