    摘要:

    目的监测南宁地区淋病奈瑟菌临床分离株对环丙沙星的耐药性。方法收集广西皮肤病防治研究所1996年1月—2008年12月性病门诊就诊患者泌尿生殖道分泌物标本中分离的970株淋病奈瑟菌,采用琼脂稀释法测定其对环丙沙星的最低抑菌浓度(MIC)。结果970株淋病奈瑟菌对环丙沙星的总耐药率为81.96%,历年的耐药率不同,呈明显上升趋势(χ2=394.49,P<0.005);1996年、2000年、2005年、2008年的耐药率分别为19.56%、93.81%、98.75%、100.00%,在1999年以前耐药率迅速上升,2000年以后保持较高水平。环丙沙星的MIC50值上升很快,1996年为0.125 mg/L,2000年为4 mg/L,2006年为8 mg/L;MIC90值也保持较高水平。结论南宁地区淋病奈瑟菌对环丙沙星耐药严重,环丙沙星等喹诺酮类药物在该地区已不适合作为治疗淋病的一线药物,应加强对淋病奈瑟菌耐药性的连续监测。

    Abstract:

    ObjectiveTo study resistance of clinical isolated Neisseria gonorrhoeae to ciprofloxacin in Nanning area. MethodsNine hundred and seventy strains of Neisseria gonorrhoeae isolated from urogenital system in patients in a dermatology institute between January 1996 and December 2008, minimum inhibitory concentrations (MICs) of ciprofloxacin were determined by agar dilution method. ResultsThe total resistant rate of Neisseria gonorrhoeae to ciprofloxacin was 81.96%, there was obviously increased tendency in resistant rate (χ2=394.49, P<0.005) with each year; drug resistant rate in 1996, 2000, 2005 and 2008 was 19.56%, 93.81%,98.75% and 100.00% respectively, drug resistant rate increased rapidly before 1999, and remained high level after 2000. The MIC50 increased from  0.125mg/L in 1996 to 4mg/L in 2000 and 8mg/L in 2006; MIC90 was also at high level. ConclusionResistance of Neisseria gonorrhoeae to ciprofloxacin is very serious in Nanning area,  fluoroquinolones such as ciprofloxacin is not suitable as the  firstline drugs for treating patients with gonorrhea in Nanning area, it is important to survey successively antimicrobial resistance of Neisseria gonorrhoeae.
