A total of 304 Neisseria gonorrhoeae isolates obtained from patients in South China from 2016 to 2020 were evaluated. The MICs of penicillin, cefuroxime, ceftriaxone (CRO), cefepime, ciprofloxacin, ceftazidime and azithromycin (AZM) against the isolates were determined by the agar dilution method. Then, Neisseria gonorrhoeae isolates were categorized into sensitive, moderately sensitive and resistant according to MICs. Also, β-lactamases were detected by enzyme linked immunosorbent assay (ELISA). Ureaplasma urealyticum and Mycoplasma hominis were determined by culture in liquid medium, and Chlamydia was detected by rapid antigen test. The result showed there was 50.99%, 20.72%, 9.87%, 14.47%, 86.84%, 7.57%, 6.91%, 11.18% resistance to penicillin, cefuroxime, ceftriaxone, cefepime, ciprofloxacin, ceftazidime and azithromycin, respectively. Also, β-lactamase positivity was 53.29% and Chlamydia antigen positivity was 20.07%. Ureaplasma urealyticum and Mycoplasma hominis positivity was 11.84% and 6.25%, respectively. From 2016 to 2020, the resistant rate of ceftriaxone and azithromycin gradually increased. In conclusion, Southern China is among the area reporting gonococci with high-level resistance to AZM and CRO, so N. gonorrhoeae culture and drug sensitivity test will be vital for monitoring trends in antimicrobial resistance.Keywords: drug sensitivity, Neisseria gonorrhoeae, retrospective analysis
