A potency assay for Bordetella bronchiseptica bacterins has been developed using mice. The immunogenicities of three bacterins, B, C, and D, were evaluated for ability to prevent death in mice as compared with a reference standard bacterin (RSB-A). Bacterins RSB-A, B, and C were evaluated for ability to prevent death in mice as compared with a reference standard bacterin (RSB-A). Bacterins RSB-A, B, and C were evaluated in swine for efficacy against nasal turbinate atrophy. Swine immunized with RSB-A demonstrated 25% gross nasal turbinate atrophy (GNTA), whereas nonimmunized swine had 85% GNTA. Swine vaccinated with bacterins B and C demonstrated 0 and 100% GNTA, respectively, whereas the nonimmunized groups had 64 and 75% GNTA, respectively. RSB-A and bacterins B, C, and D provided average mouse survivals of 94, 88, 49, and 32%, respectively when the mice were given 1/10,000 of a recommended swine-immunizing dose, whereas an average of 88% of the unvaccinated mice died.
已开发出一种使用小鼠对支气管败血波氏杆菌菌苗进行效价测定的方法。与参考标准菌苗(RSB-A)相比,评估了三种菌苗B、C和D预防小鼠死亡的免疫原性。与参考标准菌苗(RSB-A)相比,评估了菌苗RSB-A、B和C预防小鼠死亡的能力。在猪身上评估了菌苗RSB-A、B和C抗鼻甲萎缩的功效。用RSB-A免疫的猪出现25%的鼻甲肉眼可见萎缩(GNTA),而未免疫的猪有85%的GNTA。用菌苗B和C接种的猪分别出现0%和100%的GNTA,而未免疫组分别有64%和75%的GNTA。当给小鼠接种推荐猪免疫剂量的1/10,000时,RSB-A和菌苗B、C和D分别使小鼠平均存活率达到94%、88%、49%和32%,而未接种疫苗的小鼠平均有88%死亡。
