AbstractA 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. Giardia lamblia was detected in 12% of patients, rotavirus in 8%, and Cryptosporidium and Entamoeba histolytica each in 5%. Blastocystis hominis was present in 33% of patients but in only 9% of those who took trimethoprim-sulfamethoxazole. More than one enteropathogen was detected in 17% of patients. Patients with prolonged symptoms (longer than two weeks) were more likely to have Giardia (27%) and less likely to have Shigella (5%) than were patients with acute symptoms. 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.
