摘要
从患细菌性败血症的鲢肝脏中分离到一菌株，编号青1－2－3。通过人工感染试验，发病症状与自然病鱼基本一致。对致病菌株进行细菌学鉴定为嗜水气单胞菌（Aeromonashy-drophila），青1－2－3的生化表型不同于银鲫病原，为致病性嗜水气单胞菌的不同菌株。
One strain of germ is isolated from the bacterial septicemia sufferer of silver carp. It is numbered as Qing 1 - 2 - 3- The bacterial septicemia artificially duplicated has succeeded by using germ Qing 1 - 2 - 3 infect the healthy individuals of silver carp. The morphology, nutrient demand, growth characteristic and biochemical reaction of the strain has been observed. lt is found the germ of Qing 1 - 2 - 3 is Aeromonas hydroPhila. The biochemical characteristic of Qing 1 - 2 - 3 is different to the pathogenic bacteria of allogynogentic crucian carp. It is indicated that Qing 1 - 2- 3 strain is a different strain of pathogenic Aeromonas hydrophila.
