[Construction and application of prokaryotic expression system of Leptospira interrogans lipL32/1-lipL41/1 fusion gene].

lipL32/1-jlipL41/1 fusion gene and its prokaryotic expression system were successfully constructed. The expressed fusion protein had qualified immunogenicity. Both the lipL32 and lipL41 genes are extensively carried and frequently expressed by different serogroups of L.interrogans, and their expression products exhibit cross-antigenicity.
