用嗜水气单胞菌9120株制备了鱼类出血性败血症疫苗。用该疫苗分二组对白鲢进行免疫，检测免疫后白鲢血清中的抗体水平，其中加佐剂免疫组获得了较高滴度的凝集抗体，不加佐剂免疫组产生的凝集抗体滴度较低，但用间接血球凝集试验可以检出。
Hemorrhagic septicemia vaccine was prepared with Aeromonas hydrophila 9120 strain. The vaccine was divided into two groups of silver carp immunized to detect the immunized silver carp serum antibody levels, which plus adjuvant immunization group to obtain a higher titer of agglutination antibody, without adjuvant immune group produced a low titer of agglutination antibody , But with indirect hemagglutination test can be detected.
