Popis: Bovine tuberculosis (TB) is a neglected zoonosis of cattle that is prevalent but under-investigated in Cameroon. Based on epidemiological data of the disease, this study was designed to assess the risks and public health implications for zoonotic M. bovis infection in cattle and humans in the highlands of Cameroon. Evidence of bovine TB in cattle in the study region was confirmed by the following surveys: abattoir slaughter meat inspection and TB lesion detection rates of 0.20% – 1.69% (over 60.94% of all pathologies that warranted partial or whole carcass condemnation were due to TB lesions); seroprevalence rates of 37.17% and comparative cervical tuberculin test estimations of 4.67% – 7.15%, 12.02% – 15.67% and 20.56% – 24.98% at the ≥ 4mm, ≥ 3mm and ≥ 2mm cut off points, respectively. Genomic deletion analysis of cultured isolates showed evidence of M. tuberculosis from suspected cattle tissue and M. bovis from infected human sputa while spoligotyping identified five cattle M. bovis strains including four unique spoligotype patterns that had not been previously described. The study revealed that the presence of infected animals, age, sex, breed and husbandry practices served as significant (P
