Abstract:
Objective To understand the drug resistance of Neisseria gonorrhoeae in Foshan area and to detect the related drug resistant gene mutation situation.Methods 57 strains of Neisseria gonorrhoeae were collected.The drug susceptibility test was per-formed by adopting the agar dilution method.The related drug resistance genes were amplified by PCR and the PCR product se-quencing results were performed the homological searching in GenBank by the BLAST algorithm.Results The sensitive rates of Neisseria gonorrhoeae to penicillin,tetracycline,ciprooxacin,ceftriaxone and spectinomycin were 0.0%,8.8%,7.0%,61.4% and 100.0%,respectively.The rates of beta lactamase-producing Neisseria gonorrhoeae and tetracycline resistant Neisseria gonorrhoeae were 35.1% and 56.1%,respectively.The mutation rate of drug resistance genes were over 80%.Conclusion Ceftriaxone and spectinomycin can be used as the first choice drug for the treatment of Neisseria gonorrhoeae in Foshan region.The drug resistance mechanism of Neisseria gonorrhoeae is complex.The epidemiological monitoring of the Neisseria gonorrhoeae related drug resist-ance genes should be strengthened.
