Sero-Surveillance and Control of Bovine Brucellosis in Akshayakalpa Dairy Farms in Karnataka, India
Abstract:
Brucellosis is a disease of domestic animals with serious zoonotic implications in humans, causing huge economic losses to the livestock industry. The present study was conducted to find the prevalence of brucellosis in Akshayakalpa organic dairy farms. Seventeen pooled milk samples from different herds contributing to the farm were collected and subjected to milk ring test (MRT), among these seven samples were found to be positive. Individual animal milk samples were collected from the positive herds and subjected to MRT again. Further, serum samples of all MRT positive animals were screened by Rose bengal plate agglutination test (RBPT) and indirect ELISA. Prevalence rate of brucellosis was found to be 11.08%, 20.40% and 38.77% by MRT, RBPT and indirect ELISA, respectively. Farmers were educated about the risk of disease and it’s public health significance and all the affected animals were isolated. By the consent of farmers the management of the farm culled all the ten infected animals which were positive by all the above tests and financial compensation was provided to the affected farmers. Since then, the farm has adapted regular screening of new animals before introducing it to the herd and all the animals contributing to farms are free from brucellosis. In conclusion, MRT, RBPT and indirect ELISA in combination can be used for diagnosis of brucellosis and test and slaughter policy is the best method of choice to control the infection if the sizes of the positive reactors are less.
