为探讨霍乱弧菌在外环境水体中生存、生长,繁殖的时间、速度等影响因素,采用定性、定量方法研究。结果显示:霍乱弧菌可在不同水体及水底污泥中有不同的生长、繁殖,且在咸淡水交界水域的水底污泥中更佳,存在长期生长、繁殖和潜伏越冬的条件,为地方性成因及防治提供科学依据。 In order to investigate the influencing factors of survival, growth, propagation time and speed of Vibrio cholerae in external environment water, qualitative and quantitative methods were used. The results showed that Vibrio cholerae could grow and multiply differently in different water bodies and underwater sludge, and was better in the underwater sludge in the brackish water boundary zone. It had the conditions of long-term growth, reproduction and latent overwintering, Provide a scientific basis for the cause and prevention.
