RETROSPETIVE STUDY OF BOVINE TUBERCULOSIS IN ONDO STATE, NIGERIA

It is characterized by the formation of granulomas in tissues and organs, more significantly in the lungs, lymph nodes, intestines, liver and kidneys (Shitaye et al., 2007). Bovine TB is caused by a slowly growing bacillus which is a member of the Mycobacterium tuberculosis complex.

Cases of of Bovine Tuberculosis in both herd and Abattoirs have also been reported (Alhajin1976; Cadmus etal., 1999 and 2003) Abattoir records give an insight into the level of health hazards consumers are exposed to, hence the need to review some of these figures.
Records of animals slaughtered within the state in all government approved slaughter slabs/abattoirs, disease were observed at post mortem examination by Veterinary officers between 2003 to 2010 were used. Postmortem findings were based on characteristic TB lesion on organs as earlier described (Blood and Radostitis,1989; Seifert, 1996; Gracey and Collins, 1992). Data were analyzed to show frequencies of cattle slaughtered and...
