Antimicrobial susceptibility profile of Neisseria gonorrhoeae at STI clinic.

A total of 100 consecutive patients who attended a sexually transmitted infections clinic were studied. Thirteen had gonococcal urethritis, of which 10 showed growth of Neisseria gonorrhoeae on culture. All the isolates were tested for antimicrobial susceptibility by Australian Gonococcal Surveillance Programme (AGSP) method and beta lactamase production by chromogenic cephalosporin test. Four patients were co-infected with each of the following: HIV, HBV and Chlamydia trachomatis . Gonococcal urethritis (13%) was found more in male patients. Ten percent gonococcal isolates were penicillinase-producing N. gonorrhoeae , and another 10% were tetracycline-resistant N. gonorrhoeae .
