Abstract
Cell Mediated immune (CMI) responses are the principal immunological reactions in cattle to M. Bovis infection. The delayed type hypersensitivities, (DTH) as elicited by intradermal tuberculin reaction is not very specific and has several limitations in detecting tuberculosis in cattle. Serological techniques to detect circulating antibodies to M. Bovis are limited due to poor sensitivities and suboptimal specification (Costello et al., 1997). The present study compared the efficacy of tuberculin test and gamma interferon assay in detecting bovine tuberculosis.
