摘要
目的分析郴州市海、水产品霍乱弧菌污染状况及菌型特征。方法采集市场销售的海、水产品,对其整体或部分及相应的体表、肛门或鳃部涂片进行增菌、分离、鉴定。用家兔小肠段结扎实验检测O139群肠毒素。结果郴州市海、水产品霍乱弧菌带菌率为0.64%(2/311),两株霍乱弧菌均来自甲鱼(2/77),经鉴定分别为O1群和O139群,后者能产霍乱肠毒素(CT),还检出其他致病性弧菌9株。结论郴州市水产品存在O139群霍乱弧菌污染,给我们提出了一个新的卫生学问题,建议在今后的监测中采用整体或部分采集法。

Cultivation, isolation and identification of V. chelerae O1 or O139 serotypes were conducted. Results Altogether 311 sample specimens were collected and 2 strains V. chelerae were discovered, one was V. chelerae O139 and the other was V. chelerae O1, the positive rate was 0.64% （2/311）. The two strains V. chelerae were all isolated from the Chinese turtle （2/77）. The V. chelerae O139 isolated produced cholera entertoxin （CT）.
