The abundance of Aeromonas hydrophila was measured in 147 natural aquatic habitats in 30 states and Puerto Rico. Viable cell counts were used to estimate density at all sites by using Rimler-Shotts medium, a differential presumptive medium for A. hydrophila. Temperature, pH, conductivity, salinity, and turbidity were measured simultaneously with water sample collection. The density of A. hydrophila was higher in lotic than in lentic systems. Saline systems had higher densities of A. hydrophila than did freshwater systems. A. hydrophila could not be isolated from extremely saline, thermal, or polluted waters, even though it was found over wide ranges of salinity, conductivity, temperature, pH, and turbidity. Of the water quality parameters measured, only conductivity was significantly regressed with density of A. hydrophila.
在30个州和波多黎各的147个自然水生生境中对嗜水气单胞菌的丰度进行了测定。通过使用Rimler-Shotts培养基(一种用于嗜水气单胞菌的鉴别性推测培养基),采用活菌计数法来估计所有采样点的密度。在采集水样的同时测量温度、pH值、电导率、盐度和浊度。嗜水气单胞菌在流水系统中的密度高于静水系统。咸水系统中嗜水气单胞菌的密度高于淡水系统。即使在盐度、电导率、温度、pH值和浊度的广泛范围内都发现了嗜水气单胞菌,但在极端咸水、高温或污染水域中无法分离出该菌。在所测量的水质参数中,只有电导率与嗜水气单胞菌的密度呈显著回归关系。
