Brucellosis is Significantly Associated with Reproductive Disorders in Dairy Cattle of Punjab, Pakistan

Brucellosis is worldwide zoonotic infection. A total of 384 serum samples were collected from cross bred dairy cattle at three different private farms located in Gujranwala, Pakistan. The samples were analysed by Rose Bengal Plate Test (RBPT) and by indirect-Enzyme Linked Immunosorbent Assay (iELISA). The overall seroprevalence was found to be 28.90 and 27.86% by RBPT and iELISA, respectively. Previous history of animal reproductive disorders was found to be significantly associated (P=0.0056) with seropositivity of the infection. Age, sex, parity, lactation and pregnancy status of the animal were not found significantly associated. Routine herd screening, consumtion of pasteurized milk and public awareness programmes would be helpful for control and prevention of zoonotic transmission.
