Seroepidemiology of infectious bovine rhinotracheitis in Chhattisgarh, India

Infectious bovine rhinotracheitis (IBR) is important infection of bovines causing respiratory and reproductive problems and abortions leading to huge economic loss to the dairy industry. This disease is known to be transmitted through natural service and artificial insemination causing severe implication on international trade of livestock and their products. In the present study, seroepidemiology and risk factors infectious bovine rhinotracheitis were investigated in cattle and buffaloes of Chhattisgarh, India. A total of 374 serum samples from bovines were collected randomly from 94 villages of six districts of Chhattisgarh state with different attributes like districts, species, breeds, sex, age, farming sectors and clinical condition of animal. Samples were subjected to i-ELISA for detection of antibodies for IBR. The overall apparent seroprevalence for IBR was observed to be 63.9%. Statistical analyses indicated a significant difference in seroprevalence among districts (P<0.05) for all the three diseases. IBR was significantly more prevalent in Indian cattle age above 4 years and clinically ailing animals as compared to cross bred cattle, buffaloes and apparently healthy ones. Further, positivity for IBR in rearing sector and sex of animal was non-significant. The finding of the study represented a major impact on animal health and productivity.
