湾鳄(Crocodylus porosus Schneider)嗜水气单胞菌病研究

Study on Aeromanas hydrophila Collected from the Cultured Crocodilus porosus

厦门H野生动物园内饲养的一群湾鳄于2001年11月初暴发急性传染病,并引起部分死亡,病鳄表现内脏和体表出血等败血症状,从肝脏中分离出2株细菌(代号Croc01和Croc02),经鉴定分别为嗜水气单胞菌和表皮葡萄球菌.根据溶血性、动物毒力、药敏和防治试验等证实菌株Croc01即嗜水气单胞菌能产生外毒素,具有溶血性,为本次传染病的主要致病原.应用敏感药物治疗取得良好的疗效.

Some cultured crocodiles Crocodilus porosus in a wild zoo in Xiamen had broken an acute infectious disease and caused to death in November 2001. The ill crocodiles took a septicaemia symptom like visceral and body surface hemorrhage. Two strains marked as Croc01 and Croc02 isolated from the diseased crocodiles were identified as Aeromanas hydrophila and Staphylococcus epidermidis. The Croc01 strain was proved to be the major pathogen of the disease by hemolysin test, animal toxicity test, antibiotic sensitivity test and cure experiment. It can produce exotoxin and has beta hemolysin completely. The tested animals can be cured by injecting with sensitive antibiotics which had been approved to be keenness to the strain.
