Ecoligical studies on Vibrio parahaemolyticus in fresh water area at suburb of Dhaka, Bangladesh

从孟加拉国达卡郊区淡水区32份样品和孟加拉国孟加拉湾附近微咸水区或对虾养殖场53份样品中分离到嗜盐菌副溶血性弧菌。结果表明，从淡水区的1个水藻根部和微咸水地区的6个水样中分离到致病的副溶血性弧菌。此外，有时从分离的副溶血弧菌中分离出淡水型弧菌和微咸水型溶藻弧菌或河弧菌，这对致病性副溶血性弧菌的生态具有重要意义。

Halophilic bacterium of Vibrio parahaemolyticus was tried to isolate from 32 samples of fresh-water area where were in the suburbs of Dhaka and 53 samples of brackish-water area, or shrimp culture fields near the the Bay of Bengal, Bangladesh. T results showed that pathogenic V. parahaemolyticus was isolated from one of waterweed-root in fresh-water area, and 6 samples from brackish-water area. Furthermore, it swhowed greatly important for the ecology of pathogenic V. parahaemolyticus that fresh-water bacterium of V. mimicus or V. c holerae, and brackish-water bacterium of V. alginolyticus or V. fluvialis was isolated sometimes from the same samples isolated V. parahaemolyticus.
