RESUMO

<p><b>OBJECTIVE</b>To study the phenotypic and genotypic resistance to Fluoroquinolones in Neisseria gonorrhoeae (NG) isolated in Jiangsu province of China.</p><p><b>METHODS</b>In-vitro, susceptibility testing of ciprofloxacin and levofloxacin against ninety-five clinical isolates were determined by agar dilution method. Detection of mutation in the gyrA and parC genes was performed by polymerase chain reaction (PCR) assay and sequence analysis.</p><p><b>RESULTS</b>The clinical isolates demonstrated 100% resistance to ciprofloxacin. Based on gyrA and parC mutations, 18 types could be categorized among the 54 isolates. Based on the same gyrA mutations,isolates with high MIC appeared to have had more mutations in parC gene.</p><p><b>CONCLUSION</b>The status of resistance to ciprofloxacin in NG was quite serious, and ciprofloxacin treatment for the treatment of NG infections in Jiangsu province should not be recommended. The results from this study suggested that mutations in the parC gene had contributed to the development of high Fluoroquinolone resistance in NG.</p>

RESUMO

Objective To analyse the antibiotics susceptibility result of Neisseria gonorrhoeae(N.g) isolates.Method 95 strains of N.g were performed the in-vitro susceptibility test.MICs of penicillin, tetracycline, ciprofloxacin, levofloxacin, ceftriaxone, cefotaxime, cefepime, and spectinomycin were determined by agar dilution.Results Almost all of the N.g strains were susceptible to the first-line antibiotics used for treating the infection. The resistance rate to ciprofloxacin, tetracycline and penicillin were 100%, 78.9% and 68.4% respectively.Conclusion Although N.g is susceptible to first-line antibiotics used for treating the infections at the clinics, the situation of resistance to penicillin, tetracycline and ciprofloxacin is very serious.
