本实验用正常和64℃水浴一小时处理的各五十批猪丹毒弱毒冻干菌苗作为抗原,分别进行反向间接血凝试验,所得的红血球进行细胞电泳的表面电位测定。实验结果经统计处理表明,两者间的差别非常显著,这结果预示着可以用细胞电泳方法代替小动物法检验猪丹毒菌苗的效价。 In this experiment, each of the fifty batches of swine erysipelas attenuated freeze-dried bacterin treated with normal and 64 ℃ water bath for one hour was used as antigen to carry out reverse indirect hemagglutination test. The obtained erythrocytes were subjected to cell surface electrophoresis. The statistical analysis of the experimental results showed that the difference between the two was very significant, indicating that the titer of the swine erysipelas vaccine could be tested by the cell electrophoresis instead of the small animal method.
