埃尔托孤菌可在含有一定化学成份的水中粘附于丁质上,分泌几丁质酶利用几丁质而生存。根据这一原理,我们采用浙江医学研究院提供几丁质溶解环试验方法,对海南岛沿海及内陆地进行水质调查,判别各地自然水体是否能提供埃尔托孤菌利用几丁质的条件,探讨各类水质是否适合副霍乱的生存、繁殖。现将调查结果报告如下 Elto’s bacterium can adhere to butyrate in water containing a certain chemical composition, and secrete chitinase to survive using chitin. According to this principle, we use the Zhejiang Medical Research Institute to provide chitin dissolution ring test method to conduct a water quality survey of Hainan Island coastal and inland to determine whether the natural water around the country to provide elto bacteria using chitin conditions Whether or not water quality is suitable for the survival and reproduction of cholera. The survey results are reported below
