Abstract

The present study was intended to use the avidin-biotin-peroxidase-antiperoxidase complex (ABPAP) method for the identification of Mycobacterium bovis in the tissue sections of infected cattle. Antibodies and linksera for ABPAP procedure used in incubated order were rabbit anti-Mycobacterium polyvalent antibodies, goat anti-rabbit IgG, rabbit peroxidase-antiperoxidase complex, biotinyl-horse anti-rabbit IgG, and avidin-biotin-peroxidase complex. Where the bacterial antigen was localized by ABPAP, a dark brown deposit occurred in the cytoplasms of macrophages and Langerhans' giant cells of the granulomatous lesions. The method approved to be highly specific for the identification of the bacteria and allowed a precise localization of the bacterial antigen in infected cells.
