[Establishment and application of ELISAs based on rLipL32/1-LipL21-OmpL1/2 fusion antigen of Leptospira interrogans].

Objective: To establish ELISAs based on rLipL32/1-LipL21-OmpL1/2 fusion antigen of Leptospira interrogans for detecting specific IgG and IgM in serum of patients with leptospirosis.

Methods: Microscope agglutination test(MAT) was performed to detect serum specimens from leptospirosis patients and to determine titers of rabbbit antiserum agaist rLipL32/1-LipL21-OmpL1/2 to reference standard strains of L. interrogans.
