| 摘 要： | 作者等于1964—1966年和1978—1984年,应用水中弧菌的常规试验分离鉴定法,对非O-I群弧茵在芜湖地区自然水系中的分布进行了调查。结果看到,非O-I群弧菌在河流、湖泊和沟塘中广泛存在。同时发现在捕获得黑斑泥鳅231条中检出有9条胆囊里生存有大量非O-I群弧菌(自然阳性率为3.9％,可信限为1—6％),泥鳅胆囊里生存的非O-I群弧菌数平均为149,500(63,000—236,000)/毫升胆汁。 相继,作者等将非O-I群弧菌加入缸水中(每毫升缸水中含弧菌约100个)喂养泥鳅,进行了实验感染试验。在喂养的鱼种中有黑斑泥鳅和鲫鱼,在自然气温25.5—29℃下,饲养3—4周。然后,采用无菌术解剖鱼类摘取胆囊,收集胆汁用生理盐水稀释后进行弧菌培养和鉴定计数。结果,在喂养试验的黑斑泥鳅91条中,检出有23条胆囊里生存有大量非O-I群弧菌(喂养试验阳性率为25.2％,可信限为16—34％),泥鳅胆囊里生存的弧菌数平均为146,000(73,000—219,000)/毫升胆汁。可看出,泥鳅胆囊里生存的弧茁数比喂养时加入缸水中的弧菌数约高700—2000倍。但鲫鱼胆囊里未检出弧菌。由此看来,非O—Ⅰ群弧菌的繁殖生态学与水生动物有关，黑斑泥鳅可能是其中之一。作者等倾向相信非O-I群弧菌侵入泥鳅体内进入胆囊栖居繁殖，黑斑泥鳅有成为弧菌属菌群贮菌寄主和弧菌性腹泻传染源的可能性。

| Abstract: | The study on the natural distribution and reproducing ecology of Non-O-Group I V. cholerae in water of Wuhu area was carried out from 1964 to 1966 and from 1978 to 1984. The determinative and isolation of vibrios in water by routine tests.Results obtained show that the Non-O-Group I V. cholerae are widely present in river, lakes and pools. And discover at the same time, in gallbladders of 9 from 231 loaches caught, there was large number of Non-O- Groupl V.cholerae (3.9% natural positive and confidence limi... |
