ABSTRACT

Brucellosis and tuberculosis are neglected zoonoses having worldwide public health concern. The present study was undertaken to elucidate the prevalence of brucellosis and tuberculosis in caff aloes in selected farms under different production systems in Karnataka. The risk factors associated with the occurrence of these diseases were evaluated. A total of 300 caff aloes in mixed herd were examined for detection of brucellosis and tuberculosis in different production systems viz., intensive (110), semi-intensive (110) and extensive system (110). The animals were screened for brucellosis and tuberculosis by rose bengal plate test (RBPT)/milk ring test (MRT) and single intradermal tuberculin (SIT) test. The overall prevalence of brucellosis and tuberculosis was 6.06% (20/330) and 3.33% (11/330) among the animals studied. The prevalence of both the diseases was higher in farms with intensive production system and larger herd size. Sexually active (2-10 years) and aged animals (5-10 years) were at risk of infection for brucellosis and tuberculosis, respectively. Exotic breeds of cafi cant association with the individual level and herd level risk factors with occurrence of brucellosis and tuberculosis in caff aloes as evidenced by Odd’s ratio.
