Abstract: The study was taken up to note the prevalence of antibodies in the sera of bovines against Infectious Bovine Rhinotracheitis (IBR). The survey for the study of seroprevalence was carried out to detect the extent of IBR infection prevailed in the area. Infectious bovine rhinotracheitis infection, clinically exhibits rhinotracheitis, conjunctivitis, pustular vulvovaginitis and balanoposthitis, abortion, infertility, and encephalitis. Three hundred and sixty three bovine serum samples were procured from the suspected clinical cases of IBR in different mandals of Palnadu district of Andhra Pradesh. The sera were processed for the detection of antibodies against IBR using indirect enzyme linked immunosorbent assay (Indirect ELISA). The results showed that IBR antibodies were profoundly prevalent in many mandals of the Palnadu district with an overall prevalence rate of 40.22%. Of the 363 serum samples tested, 146 samples were tested positive for the Infectious bovine rhinotracheitis in bovines. The prevalence in cattle was 39.04% and buffaloes was 41.01% which was statistically not significant. On sex wise basis, it was found that females (48.03%) had higher level of antibodies than males (14.29%). Age-wise seroprevalence differed significantly with higher seroprevalence (56.70%) among adults (over 7 years of age) with least seroprevalence in below three years of age group (17.86%) indicating animals of older age were more susceptible. The present paper indicated the prevalence and current status of IBR infection in Palnadu district of Andhra Pradesh.
