Cholera epidemics occur twice a year in the endemic area of Bangladesh. Vibrio cholerae 01 can be isolated from the environment only during the epidemics and the question of possible interepidemic environmental reservoirs of V. cholerae remains open. The present laboratory-based studies investigate the role of an aquatic alga, Anabaena variabilis, as a possible reservoir. Persistence of V. cholerae inside the mucilaginous sheath of A. variabilis was observed by phase-contrast and fluorescent microscopy for more than 15 months after inoculation.
在孟加拉国的霍乱流行地区，每年会发生两次霍乱疫情。只有在疫情期间才能从环境中分离出霍乱弧菌O1群，霍乱弧菌在疫情间歇期可能存在的环境储存宿主问题仍未解决。目前基于实验室的研究调查了一种水藻——多变鱼腥藻作为可能储存宿主的作用。通过相差显微镜和荧光显微镜观察到，接种后15个多月霍乱弧菌在多变鱼腥藻的黏液鞘内存活。
