Gonorrhoea and Urogenital Chlamydial Infection in Female Prostitutes in Tegucigalpa, Honduras

The prevalence of gonorrhoea and urogenital chlamydial infection was investigated in female prostitutes in Tegucigalpa, Honduras. Epidemiological data were recorded according to a standardized questionnaire. The median age of the prostitutes was 27 years and the median period of prostitution was 2-4 years. Most of the women (91%) had no occupation other than prostitution and 57% of them had not even completed primary school. In 233 cases when both gonococcal culture and chlamydial antigen detection with a commercial EIA kit were performed the prevalence of gonorrhoea was 25% (59) and that of chlamydial infection 31% (72). Both diseases were recorded in 9%. The women who had been prostitutes for 2 years or longer had gonorrhoea (P less than 0.01) or chlamydial infection (P less than 0.05) less frequently than those who had practised prostitution for a shorter time period. Among 70 different gonococcal isolates from 241 prostitutes, 40 (57%) belonged to serogroup W II/III. Most (83%) of the 30 W I isolates were beta-lactamase producing (PPNG) like 42% of the W II/III isolates. All non-PPNG isolates, except one had decreased susceptibility to benzylpenicillin (MIC greater than or equal to 0.125 mg/l) and all isolates were susceptible to spectinomycin. Four out of five isolates from the throat were PPNG and the fifth had a benzylpenicillin MIC of 0.5-2.0 mg/l.
