Polyclonal antisera were raised in rabbits against preparations of live and heat-killed Mycobacterium paratuberculosis and cell-wall proteins of M. paratuberculosis and were evaluated as diagnostic tools in immunohistochemical staining of bovine tissue. Live preparations of M. paratuberculosis (LMp) were inoculated intraperitoneally or intravenously at 10(9)/ml. Heat-killed M. paratuberculosis (HKMp) was prepared by treatment of bacteria at 85 C for 10 minutes. Cell-wall proteins were isolated from M. paratuberculosis and conjugated to keyhole limpet hemocyanin to improve antigenicity (KLH-CWPMp). The HKMp and KLH-CWPMp preparations were emulsified in incomplete Freund's adjuvant before subcutaneous inoculation of rabbits. Antibody titers in the terminal blood sample were higher for HKMp and KLH-CWPMp than for LMp rabbits (1:1,024 vs. 1:64). The KLH-CWPMp antibody did not cross-react with M. bovis-infected tissues. Sensitivity and specificity of immunohistochemical detection of Johne's disease (paratuberculosis) from bovine tissues was much higher for the KLH-CWPMp polyclonal antibody. Immunoreactivity of the antibody resulted in staining of bacteria in the cytoplasm of macrophages, mononuclear giant cells, and extracellular bacteria in both intestine and lymph node.
