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

从孟加拉国达卡郊区的32个淡水地区和孟加拉湾附近的咸水地区或虾养殖场的53个样品中分离出嗜盐性副溶血性弧菌。结果表明，从淡水区水草根中分离到致病性副溶血性弧菌1株，从咸水区分离到致病性副溶血性弧菌6株。此外，从分离出副溶血性弧菌的同一样品中，有时还分离出淡水细菌模拟弧菌或裂孔弧菌，以及咸淡水细菌溶藻弧菌或河流弧菌，这对致病性副溶血性弧菌的生态学具有重要意义。

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.
