A Comparison of One-Step Anigen® Rapid Bovine Tuberculosis Antibodies Test Sensitivity to Postmortem Gross Lesions in Diagnosing Bovine Tuberculosis in a Dairy Herd in Kaduna State

Sixteen lactating Bunaji dairy cows were screened for bovine Tuberculosis (bTB) using one-step Anigen® Rapid Bovine Tuberculosis Antibody Test (IQRT) specific for Mycobacterium bovis (M. bovis) antibodies. About 62% (10/16) of the lactating Bunaji cows screened were positive for antibodies to M. bovis. Six out of the ten positive cows were randomly selected culled and postmortem examination was conducted on them for the presence or absence of bTB gross lesion. Gross lesion was not observed in any of the culled cows examined. Though, the cows were exposed to M. bovis, probably infection is inapparent because bTB is a progressive and chronic disease.
