Seroprevalence patterns of bovine brucellosis in organised and unorganised farms of coastal Andhra pradesh, India

Brucellosis is an economically important infection of livestock and humans due to the reproductive problems it causes and also the risk to the public health.A study of bovine brucellosis was conducted using different serological tests to determine the disease status in an organized dairy farm and two private dairy farms in coastal area of Andhra Pradesh.A total of 445 serum samples from 200 cattle and 245 buffaloes were screened using Rose Bengal plate test (RBPT), Serum agglutination test (SAT), Lateral flow assay (LFA) and Indirect enzyme linked immunosorbent assay (i-ELISA).An overall prevalence of 9.88%, 7.78%, 6.29% and 7.86% was detected by RBPT, SAT, LFA and i-ELISA respectively.The present study identified overall high prevalence of bovine brucellosis in un-organized private farms particularly in female white cattle.RBPT and i-ELISA can be used successfully to declare the disease status of the herd and to implement control programmes like test and culling of the affected animals and adoption of strict hygienic measures in the farm.
