Sero-prevalence of paratuberculosis in young kids using ‘Bison type’, Mycobacterium avium subsp. paratuberculosis antigen in

Two Mycobacterium avium subsp. paratuberculosis (MAP) antigens (native—S 5, ‘Bison type’ and commercial antigens ‘Bovine’), were compared for screening of kids against paratuberculosis infection. Using MAP (S 5) antigen (‘Bison type’) in plate ELISA, 47 serum samples driven from farmerʹs herds of Jakhrana, Sirohi, and Marwari breeds in their home tract in Rajasthan state were screened. Of the 47 kids randomly sampled, 8.5% were found sero-positive by plate ELISA test. Breed-wise sero-prevalence was 10.5%, 7.6%, and nil in the Jakhrana, Sirohi, and Marwari male kids, respectively. Whereas, none of the serum sample was found positive using commercial MAP ‘Bovine’ antigen. Sero-prevalence of paratuberculosis has been found to be low in young kids (2 months old) belonging to the farmerʹs herds of Jakhrana and Marwari in their home tracts
