Abstract
Background: This study attempted to elucidate the spectrum of sexually transmitted infections in a tertiary care centre in North India and to assess the antimicrobial resistance in Neisseria gonorrhoeae. Materials and Methods: Antimicrobial resistance pattern of N. gonorrhoeae was determined by the standard techniques. Genotypic detection of gyrA, parC and bIaTEM genes was also carried out. The results of gyrA gene by polymerase chain reaction were confirmed by DNA sequencing. Results: N. gonorrhoea was identified in 10 (4.98%) patients, and antimicrobial sensitivity was performed in seven patients. All the seven patients tested were quinolone-resistant N. gonorrhoeae (QRNG), 5/7 were penicillinase-producing N. gononhocae, 117 was chromosomally mediated penicillin-resistant N. gonorrhoeae and 317 were tetracycline-resistant N. gonorrhoeae. Minimal inhibitory concentration (MIC) by B-test was perfonned in five strains, and we observed that MIC90 for c iprofloxacin was >= 4 mu g/ml, for penicillin was >= 6 mu g/ml and for tetracycline was 12 mu g/ml, which clearly brackets than as resistant isolates. The presence of TEM gene was confirmed genotypically in six out of seven cases. In all seven cases, gyrA and parC were observed, thus confirming their QRNG status. Conclusion: Alarming increase in the resistance to commonly used antimicrobials for gonorrhoea in our study, especially of fluoroquinolones, is a clarion call for the urgent need for prudence in prescribing them. Observing the rampant resistance exhibited by N. gonorrhoeae, it is clear that the day is not far when it will acquire a superbug status and become intractable to treatment by the available antibiotics.
