| description | Secretome (extracellular proteins) has been considered as a potential diagnostic biomarker, vaccine and therapeutic candidates for bacterial infections. In this research, secretomes of two reference Leptospira spp, namely, pathogenic L. interrogans serovar Autumnalis strain Akiyami and saprophytic L. biflexa serogroup Semaranga serovar Patoc strain P136 were evaluated for their immunogenicity to microscopic agglutination test (MAT)-positive leptospirosis patients’ sera in IgM- and IgG-ELISAs in comparison to a whole Leptospira homo-genate antigen. At a single serum dilution of 1:1,000, sensitivity of the pathogenic Leptospira secretome antigen-based IgM- and IgG-ELISAs was 90% (18/20) and 75% (15/20), respectively, when compared with that of the MAT assay. Thus, Leptospira secretome provides a potential antigen source in serodiagnosis of leptospirosis. |
