Abstract
Aim of the present study was to know the
prevalence of brucellosis in food animals in relation to various risk factors
through different diagnostic tests. For this purpose, 2375 serum samples were
collected from December, 2010 to December, 2012. Rose Bengal Plate Test (RBPT)
and Serum Agglutination Test (SAT) were applied for initial screening, positive
samples were subjected to enzyme linked immunosorbant assays (i-ELISA and
c-ELISA) for confirmation. The data thus
collected was interpreted and subjected to Binary Logistic Regression Analysis
to know the difference among various groups based on species, sex, age, body
weight and parity. Through RBPT and SAT, the higher prevalence of caprine
brucellosis was recorded as compared to the buffaloes, camel, cattle and sheep.
Prevalence of brucellosis was higher in buffaloes through both types of ELISAs
as compared to other food animals. No animal was found positive for brucellosis
in camel population. The prevalence of brucellosis was not associated with sex
of animals. Sero-prevalence was higher in mature animals as compared to the
younger ones in all food animals. The other risk factors like body weight and
parity also affected the sero-prevalence of brucellosis in all species.
