Mycobacteria cause major diseases including human tuberculosis, bovine tuberculosis and Johne's disease. In livestock, the dominant species is M. bovis causing (bTB), a disease of global zoonotic importance. this study, we estimated prevalence in slaughter cattle Cameroon. A total 2,346 were examined cross-sectional study at four abattoirs Up to three lesions per animal collected for further retropharyngeal lymph node was from random sample non-lesioned animals. Samples cultured on Lowenstein Jensen media BACTEC MGIT 960 system, identified using Hain® Genotype kits. 207/2,346 with bTB-like lesions, representing 4.0% (45/1,129), 11.3% (106/935), 23.8% (38/160) 14.8% (18/122) Bamenda, Ngaoundere, Garoua Maroua respectively. The minimum 2.8% (1.9-3.9), 7.7% (6.1-9.6), 21.3% (15.2-28.4) 13.1% (7.7-20.4) One strains recovered high public health concern limits potential control options setting without viable vaccine as an alternative.
