RESUMEN
A total of 105 subjects comprising 74 pregnant women, 26 STD patients and 5 commercial sex workers were randomly selected to detect the prevalence of syphilis, gonorrhoea and chlamydial infections. Syphilis was most prevalent among MCH clinic attendants with overall seroprevalence of 15.2 per cent; 10.8 per cent of antenatal cases, 19.2 per cent of STD patients and 60 per cent of CSWs were observed to be either TPHA reactive or both VDRL and TPHA positive. Gonorrhoea was detected in 6.7 per cent of total tested group. Gonococcal infection was not observed in antenatal cases. Neisseria gonorrhoeae isolated were found to be less sensitive to Penicillin, susceptible to Ciprofloxacin and Ceftriaxone. Beta lactamase producing strains and Tetracycline resistant N. gonorrhoeae were not observed. Chlamydial antigen detected by ELISA was observed in 4.8 per cent of total tested group. 5.4 per cent of antenatal cases (4/74) and 3.8 per cent of STD patients (1/26) were positive for chlamydial antigen. 22.9 per cent of clinic attendants were found to be infected with one or more sexually transmitted diseases.
