摘　　要：本文对东北地区流行的鲤隐性败血症进行了病原菌的分离、人工感染、病原菌生理、生化特性和药物敏感性的测定，观察了病理组织变化等。从病鱼内脏分离到场２２株致病菌，其中标７株的生长及生化特性均符合嗜水气单胞菌种的特性，嗜水气单胞菌ｈｅｃ毒素检测呈阳性。有３株菌Ｖ－Ｐ（－）、赖氨酸（－）、葡萄糖产气（－）是区别嗜水气单胞菌（Ａｅｒｏｍｏｎａｓｈｙｄｒｏｐｈｉｌａ）及温和气单胞菌（ＡＳｏｂｒｉｅ）的主要特征，这三株菌符合豚鼠气单胞菌（ＡＣａｖｉａｅ）种的特征。Abstract strains of pathogenic bacteria were isolated from epizootic septicemia of diseased carp,studied by artificial infection testing biochemical physiological characteristics and sensitivity to drugs of the pathogen observing the pathological of ill fish from novtheastern China during 19921995.The isolates were tested for motr than 40 unit characters,according to the Bergey's Manual of systematic Bacteriology 9th ,17 strains classified as Aeromonas hydrophila and 3 strains classified as a caviae.
