| Abstract: | Seroprevalence of bovine respiratory syncytial virus (BRSV) infection in both exotic and crossbred cattle were described. A baculovirus expressed recombinant purified nucleocapsid (N) protein was used in indirect and sandwich ELISA for screening of 499 bovine sera samples from all over the state for the presence of BRSV antibodies. The seroprevalence rate of BRSV was found to be 46.09% through indirect ELISA while it would found to be 65.33% by sandwich ELISA. The result also indicated that exotic breeds were more susceptible to BRSV infection compared to crossbred cattle. A comprehensive analysis on susceptibility to BRSV as regards to various factors like age and sex was also summarized. |
