Detection of Brucella Antibodies in Sheep with Special Aspect of Clinicalstatus and Breed

Brucellosis is an important zoonosis and a significant cause of reproductive losses in animals. To ascertain the serological status of the disease, a total of 1373 samples were screened for the presence of Brucella antibodies by RBPT and i-ELISA. Overall seroprevalence recorded in sheep was 6.84% (94 samples out of 1373) and 4.80% (66 out of 1373) by RBPT and i-ELISA respectively. Clinical status wise seroprevalence was recorded in heifer 4.65% and 6.97%, clinically healthy animals 2.62% and 1.79%,animals with the history of abortion 16.58% and 13.98%, hygroma 27.27% and 18.18%,pregnant 4.59% and 2.29%, non-pregnant 6.80% and 4.18%, status unknown 10.78% and 6.86%, still birth 17.64% and 5.88%, retention of placenta 20.00% and 20.00%,orchitis16.12% and 9.67% respectively by RBPT and i-ELISA, respectively. Breedwise highest seroprevalence was recorded in Patanwadi 7.82% and 5.99% followed by Marwadi 6.35% and 4.16%,Magra 3.84% and 1.28%, Avikalin 4.76% and 0.00%and Chokhla 1.78% and 0.00%by RBPT and i-ELISA, respectively. Present study revealed that the Patanwadi breed of the sheep is relatively more susceptible and high rate of seroprevalence was observed from the animals having history of abortion, retention of placenta and hygroma.
