title: Immunological reactions caused by infection with Mycobacterium paratuberculosis. A review.
abstract: The natural resistance of cattle to infection with Mycobacterium paratuberculsis in relation to their immunological reactions is recorded. In vivo and in vitro manifestations of cell-mediated immunity during infection are reviewed, together with the antibody responses. It is suggested that three distinct immunological states may arise following exposure to infection.
