摘要
从患出血病罗非鱼的血液、肝、脾分离出嗜水气单胞菌 (Aeromonashydrophila) ,经动物回归和理化试验鉴定 ,确诊嗜水气单胞菌为罗非鱼出血病病原 ;用分离菌制成的饵料吸附型疫苗进行田间试验 ,免疫组罗非鱼保护率为 87.1%,未免疫组存活率为 5 9.9%,两组间差异极显著 (P <0 .0 1)
Aeromonas hydrophila were isolated from blood, livers and spleens of Tilapia niloptica with hemorrhagic disease, which were recognized as the causative agent causing hemorrhagic disease in fish by artificial infection of fishes and physiologic biochemical characaterization of the isolate. The field tests of vaccination of Tilapia niloptica with baitadsorbed vaccine developed with the isolate were performed and the survival rate of the vaccinated group was 87.1% and the control group 59.9%.
