摘　　要：目的了解泉州地区历年霍乱菌型变迁及药物耐药性,为霍乱防治工作提供参考。方法对泉州地区1962-2010年霍乱流行疫情资料进行回顾性分析;采用WHO推荐的改良K-B纸片法,对部分菌株进行抗菌药物的药敏试验。结果 1962-2010年,泉州共发生4次较大规模的霍乱流行,流行菌型由O1小川型与O1稻叶型交替进行。大多数霍乱弧菌对诺氟沙星和环丙沙星敏感,敏感率分别为92.31%和99.20%;磺胺类药物敏感性逐年降低,对其它抗菌药耐药;O139群霍乱弧菌的耐药性明显高于O1群霍乱弧菌,不同年份的菌株耐药的程度不一致。结论泉州地区霍乱流行优势菌型为O1群霍乱弧菌,由小川型与稻叶型交替进行;霍乱弧菌对抗菌药物的敏感性逐渐下降。Objective To study the epidemic isolates and antibiotic resistance of Vibrio cholera in Quanzhou,and provide the references for prevention and control of cholera. Methods Retrospective analysis was adopted based on the epidemiological data on cholera in Quanzhou during 1962-2010.The antibiotic susceptibility of all the strains to antibacterials was determined by improve K-B method recommended by WHO. Results There were four cholera disease outbreaks occurred in Quanzhou city during 1962-2010. The dominant serotype that caused epidemics showed vicissitudinous phenomenon. Vibrio cholerae serotype Ogawa and Inaba were sensitive to norfloxacin and ciprofloxacin with a susceptibility of 92.31% and 99.20%, respectively.The resistance to sulphanilamide was increased year by year and the resistances to other antibiotics were high. The drug resistance of Vibrio cholerae O139 strains was higher than that of Vibrio cholerae O1. Conclusions The dominant biotype of Vibrio cholerae was El Tor in Quanzhou city.Vibrio cholerae serotype Ogawa and Inaba that caused epidemics showed vicissitudinous phenomenon. The antibiotics sensitivity of Vibrio cholerae was gradually declining.
