Prevalence of bovine brucellosis and risk factors assessment in cattle herds in jigawa state.

A serological survey of Brucella antibodies was carried out in Jigawa State, northwestern Nigeria to determine the prevalence of the disease and risk factors among some pastoralist cattle herds. A total of 570 cattle of different ages and sexes selected from 20 herds across the four agroecological zones in the state were screened using Rose Bengal Plate test and competitive enzyme immunoassay. From the results 23 cattle (4.04%) were positive by Rose Bengal Plate Test while 22(3.86%) were positive with competitive enzyme immunoassay. The infection rate was higher in females than males. Cattle older than 3 years had a higher prevalence rate compared to age groups 2-3 years, 1-2 years, and less than 1 year. The prevalence rate was higher in cattle densely populated locations. Infection rate differs between herds with larger herds presenting high prevalence due to poor sanitary practice. It is hereby recommended that public enlightenment on adequate control and preventive measures using proper sanitary practice and calf hood vaccination are required.
