318株副溶血性弧菌的血清分型和耐药性分析

Serotyping and drug resistances of 318 Vibrio parahaemolyticus strains

  • 摘要: 目的 通过对副溶血性弧菌菌株的血清、耐药性检测,了解上海市浦东地区副溶血性弧菌主要血清群、血清型及耐药状况,预防副溶血性弧菌引起的食物中毒和急性肠炎,为指导临床合理用药提供依据。 方法 用WHO推荐的K-B纸片法,参照CLSI抗菌药物敏感性试验标准(2005版)进行耐药性鉴定;血清学检测采用玻片凝集法。 结果 从318株副溶血性弧菌分离株中,共分出9个群,44个血清型,O3:K6型共检出134件,占42.14%,是引起食物中毒和急性肠炎的主要血清型;菌株对氨苄西林的耐药率在95%以上,对氯霉素、头孢噻肟、四环素等也存在耐药现象,对头孢他啶、头孢吡肟、庆大霉素等8种抗生素则完全敏感。 结论 有必要加强对O3:K6型副溶血性弧菌的监测,包括对其耐药情况的监测,警惕超级耐药株出现。

     

    Abstract: Objective To understand the serogroup, serotype and drug resistance of Vibrio parahaemolyticus (VP) in Pudong district in Shanghai and provide evidence for the prevention of the disease caused by VP and rational use of antibiotics. Methods Slide agglutination test was conducted to detect VP serogroup, and the drug susceptibility test of VP was conducted according to WHO and CLSI standards. Results A total of 318 VP strains were detected. There were 9 serogroups and 44 serotypes and 134 strains (42.14%) belonged to serotype O3:K6-the major panthogen causing food poisoning and chordapsus. The resistant rate of the VP strains to ampicillin was over 95%, and the resistances to chloramphenicol, cefotaxime and tetracycline were detected too, but no resistance to other 8 antibiotics, including ceftazidime, cefepime and gentamicin were detected. Conclusion It is necessary to strengthen the surveillance of Vibrio parahaemolyticus serotype O3:K6 as well as its drug resistance to prevent the emerging of super resistant strain.
