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.

Comparative Study
Comparison of HIV-antibody prevalence in patients consenting to and declining HIV-antibody testing in an STD clinic.
All patients attending a sexually transmitted disease (STD) clinic were offered voluntary, anonymous human immunodeficiency virus (HIV)-antibody testing and counseling as part of routine clinical evaluation. During a three-month evaluation period, 82% of patients accepted HIV testing. Testing was accepted equally by men and women and by heterosexual and homosexual men. ⋯ Male homosexuals and black and Hispanic men who refused testing were 7.3 and 8.8 times, respectively, more likely to be infected with HIV than were their counterparts who accepted testing. Human immunodeficiency virus testing and counseling should be routinely offered to STD clinic patients. Male STD clinic patients, especially homosexual or minority men, who refuse voluntary HIV testing should be counseled regarding reducing their risk for HIV transmission.
