摘要: 为了解上海市售水产品中副溶血性弧菌的耐药情况,通过药敏纸片扩散法（K-B法）对上海市某水产品市场连续两年监测分离获得的45株副溶血性弧菌进行了25种常用抗生素的药敏实验。结果显示,所有实验菌株都对青霉素G和甲硝唑耐药,有高达90%以上的菌株对帕拉西林、新霉素和卡那霉素耐药,而对利福平、万古霉素、四环素、强力霉素、头孢拉定和土霉素全部敏感;同时发现不同来源的菌株,其耐药谱存在一定程度的差异,菌株多重耐药性与菌株致病因子类型间也存在一定的相关性。因此,应进一步加强水产品中细菌耐药性的监测,并采取更有效措施控制细菌耐药性。Abstract: The aim of this study was to survey and analyze the antibacterial resistance of Vibrio parahaemolyticus,which were isolated from the commercial aquatic products in Shanghai markets.45 V.parahaemolyticus strains were isolated in two years,and all the isolates were carried out for 25 kinds of antibiotic susceptibility pattern using modified Kirby- Bauer disk diffusion method.The results showed that all strains were resistance to Penicillin G and Metronidazole.More than 90% of the V. parahaemolyticus isolates were resistant to Piperacillin,Neomycin and Kanamycin,and all strains were sensitive to Rifampicin,Vancomyci,Tetracycline,Doxycycline,Cephradine and Oxytetracycline.Moreover,antibiotic resistance patterns of the strains existed a certain differences among isolation origin.And there was a certain relation between the multi- drug resistance and pathogenic types of the strains.For this reason, it is important to take measures to strengthen monitor the antibacterial resistance of V.parahaemolyticus in the contaminated aquatic products.
