Abstract

A total of six hundred ninety nine (699) blood samples were collected randomly from cattle population of different cattle farms belonging to rural unorganised sectors and organised cattle farms of seven different districts of West Bengal to study the seroprevalence of infectious bovine rhiniotracheitis (IBR) by Virus Neutralization Test (VNT). The seroprevalence of IBR among the cattle population of West Bengal was estimated to be 48.15% on district-wise study (highest seroprevalence rate of 85.29% in the cattle population of Nadia district and lowest rate of seroprevalence of 20.72% in the cattle population of Jalpaiguri district) and 42.32% on sampling area-wise study. Eighteen (18) serologically positive serum samples were selected as representative samples which were subjected to two fold end point titration. The end point titration of the seropositive samples collected from organised cattle farm of organised sector showed the IBR antibody titre to range from 1: 1 to 1: 8, while that of the samples collected from rural unorganised sector showed the titre to range from 1: 1 to 1: 64. Cultural isolation and identification of bovine herpes virus-1 (BHV-1) was attempted from thirty nine (39) nasal swab specimens collected from both seropositive and seronegative animals of organised cattle farms of West Bengal. No positive BHV-1 isolate was being isolated and identified in MDBK (Madin Darby Bovine Kidney) cell culture.
