Abstract Tuberculosis concurrent infection in cattle and their respective owners in North-western Ethiopia had been investigated. Two hundred and ten cattle owners and 1220 heads of their cattle were included in the study to determine degree of tuberculosis infection in cattle owned by tuberculosis patients and tuberculosis patients. Comparative intradermal tuberculin test, bacteria culturing, acid fast staining and biochemical tests were used to conduct the study. The prevalence of tuberculosis was significantly (P < 0.001) higher in cattle owned by tuberculosis patients than in cattle owned by non-tuberculosis owners, and infection with tuberculosis was threefold greater in cattle owned by tuberculosis-positive owners. Further more, cattle owners who consumed raw milk were at higher risk (P < 0.001, OR = 3.23) for tuberculosis infection than those who consumed boiled milk. Mycobacterium tuberculosis (15.4\%), Mycobacterium bovis (44.1\%) and atypical mycobacteria (38.5\%) were identified from milk collected from tuberculin-positive cows using biochemical tests. Similarly M. tuberculosis (74.5\%), M. bovis (14.9\%) and atypical mycobacteria (8.5\%) were identified from sputum and fine needle aspiration specimens of tuberculosis patient cattle owners. Mutual transmission of mycobacterium from animals to humans and vice versa has been signified. © 2009 Blackwell Verlag GmbH.
