摘　　要：报道从湖北省宜都市和长阳土家族自治县内清江河内养殖网箱中患病斑点叉尾童啦4体内和体表分离致病菌的初步鉴定结果。从患病斑点叉尾鲴上共分离19个菌株，经分别采用注射和浸泡法人工感染试验，证明其中11个菌株能导致试验鱼80％～100％的死亡。根据对菌株的形态和生化特性的测定结果，11个菌株中的BH-001、BH-005、BH-009和BH-011等4个菌株属于叉尾鮰爱德华菌（Edwardsiella ictaluri），而BH-002、BH-015、BH-017和BH-019等4个菌株属于嗜水气单胞菌（Aeromonas hydrophila）。而BH-004、BH-013和BH-016等3个菌株尚未能鉴定其种类。The pathogenic bacteria were isolated from the diseased channel catfish, Ictalurus punctatus, and identified. Healthy channel catfish were infected by injection and immersion with 19 strains of the isolated bacteria. Among the 19 strains, 11 strains induced 80%～100% mortality. According to the morphological feature and biochemical characteristics of the isolates, strain BH-001, BH-005, BH-009 and BH-011Y62001 belong to Edwardsiella ictaluri, strain BH-002, BH-015, BH-017 and BH-019 belong to Aeromonas hydrophila.
