dc.description.abstractBACKGROUND & OBJECTIVES: Leptospirosis is a severe and complex zoonotic disease prevalent in many countries including India. Current leptospiral research is focussed on the identification of the outer membrane proteins (OMPs) of the organism that could be used in developing diagnostic assays for leptospirosis. METHODS: The Leptospira interrogans serovar Canicola was grown in EMJH medium and the cells were subjected to sarcosyl detergent treatment. The sarcosyl soluble (SS) and sarcosyl insoluble (SI) fractions were analyzed by SDS-PAGE and immunoblotting to deduce their protein profile and identifying various immunodominant antigens. RESULTS: The protein profile of SS fractions indicated the presence of three major bands of 41, 32 and 25 kDa and minor bands of 85 and 46 kDa. The SI fraction in serovar Canicola revealed the presence of 112, 93, 77, 43, 36, 29 and 22.5 kDa as major bands and minor bands of 102 and 53 kDa. In immunoblotting, the SS proteins of 41, 32 and 25 kDa and SI proteins of 112, 77, 36 and 22.5 kDa were detected to be major immunogenic proteins. INTERPRETATION & CONCLUSION: In our study immunogenic proteins were extracted from SS and SI fractions and OMPs were similar to those reported in other pathogenic Leptospira strains. These OMPs being unique to all the pathogenic leptospires, can be targeted for diagnostic purpose. Further analysis of the cellular location and expression of leptospiral proteins will be useful in the annotation of genomic sequence data and in providing insight into the biology of Leptospira cells.en_US
