OBJECTIVE: To study the epidemiology of antibiotic resistant strains of Neisseria gonorrhoeae from sexually transmitted disease clinics in The Gambia. MATERIALS AND METHODS: One hundred and sixty five strains of N gonorrhoeae were tested for their antibiotic susceptibility, auxotype, serotype, and plasmid content. RESULTS: Of the total population 84 (51%) were non-penicillinase producing (nonPPNG) and 81 (49%) penicillinase-producing N gonorrhoeae (PPNG). There were 16 serovars, five auxotypes and 33 auxotype/serovar (A/S) classes in the total population and the nonPPNG. Among PPNG only five serovars, two auxotypes and nine A/S classes were found. One A/S class predominated, NR/IB-7 (86 isolates), of which 66 (77%) were PPNG and the remainder were chromosomally-mediated resistant N gonorrhoeae (CMRNG). These strains also showed reduced susceptibility to ciprofloxacin, ceftriaxone and tetracycline and were evenly distributed among patient groups. CONCLUSION: We have identified a relatively homogeneous gonococcal population with a core group of isolates exhibiting high levels of antibiotic resistance.

In this study, a total of 647 vaginal discharge samples were examined. Ureaplasma urealyticum growth was seen in 68 samples (10.5%). The antibiotic sensitivity of 30 types of U.urealyticum was determined with the E-test and agar dilution method. With the agar dilution method, all types were sensitive to ciprofloxacin and ofloxacin (MIC 0.94 microg/ml), tetracycline (MIC 0.125 microg/ml) and doxycycline (MIC 0.125 and 0.190 microg/ml). Furthermore, with the agar dilution method, 18 types (60%) were resistant to roxithromycin and 12 (40%) were sensitive (MIC 12 microg/ml); 3 types (10%) were resistant to erythromycin and 27 (90%) were sensitive (MIC 12 microg/ml); 9 types (30%) were resistant to clarithromycin and 21 (70%) were sensitive (MIC 12 microg/ml), and all types were sensitive to azithromycin (MIC 14 microg/ml).
