在仔猪副伤寒活疫苗生产过程中,加入碱性成纤维细胞生长因子（bFGF）,以观察在菌液培养过程中bFGF对活菌数和菌存率的影响。经过对所制备的3批仔猪副伤寒活疫苗在冻干前和冻干后进行了活菌计数和活菌率的计算。结果表明,在培养过程中添加了bFGF的仔猪副伤寒活疫苗,其活菌数和活菌率均高于对照组。

In this test basic fibroblast growth factor（bFGF） was added in bacterial culture in order to observe the effect of bFGF on the living bacteria number and in preparation of paratyphus living vaccine for piglets and the survival rate after freeze-dried. Living bacterial number of 3 batches of paratyphus living vaccine for piglets was counted before and after freeze-dried and the survival rate of bacteria was calculated. The results showed that living bacteria number and the survival rate of vaccines of test groups were higher than the control group.
