Lymphocyte unresponsiveness to PPD tuberculin in badgers infected with Mycobacterium bovis
Abstract
Lymphocyte transformation tests using phytohaemagglutinin and concanavalin A showed that both T and B lymphocytes are functional in tuberculous badgers. Dose response curves indicated that purified protein derivative sensitised lymphocytes were suppressed when cultured in the presence of the antigen.
