由于小肠结肠炎耶尔森氏菌(简称耶氏菌)常引起肠道感染,且可成为多种疾病和食物中毒的病原,因而在国内、外已引起广泛注意和重视。该菌在自然界分布甚广,除与人类关系密切的家禽、家畜及其有关食品外,污水也是耶氏菌的一个天然繁衍场所。但目前这方面的资料不多,为了解污水中耶氏菌的分布、血清和生物型别及污染程度,为污水处理提供科学依据,特于1985年1～4月对长沙市区不同类型污水进行了检测,结果报告如下。
Yersinia enterocolitica (often referred to as Yersinia) often causes intestinal infections and can become the causative agent of various diseases and food poisoning. Therefore, it has drawn wide attention and attention both at home and abroad. The bacteria are widely distributed in nature. Apart from poultry, livestock and related foods closely related to humans, sewage is also a natural breeding ground for Yersinia pestis. However, there is not much information in this area at present. In order to understand the distribution of Yersinia in sera, serum and biological types and degree of pollution, it provides a scientific basis for sewage treatment. Especially from January to April 1985, The tests were carried out and the results reported below.
