THE ANALYSIS OF ANTIGENIC COMPONENTS OF LEPTOSPIRA SUBCULTURED IN COMPOUND GELATIN MEDIUM
钩端螺旋体在复方明胶培养基中长期传代培养的抗原性分析

Four different strains of Leptospira were subcultured in CGM in contrast with in Korthof medium for three years. The antigenic components of these Leptospira grown in the two medium were analysed by the methods of MAT, CIE and SDS-PAGE. The results showed that:1, the antigenic components of Leptospira were very complex and had more than twenty bands stained with Coomassie brilIiant blue in SDS-FAGE pattern; 2. the antigenicity of Leptospira subcultured in CGM for many generations was relative stability and the same as that in Korthof medium.
