Prevalence of bovine respiratory syncytial virus (BRSV) and bovine herpesvirus-4 (BHV-4) in cattle from Ethiopia

A serological study was done to establish the occurrence and determine the prevalence of two important respiratory tract pathogens, bovine respiratory syncytial virus (BRSV) and bovine herpesvirus-4 (BHV-4), in cattle in Ethiopia. Prevalence rates for specific antibodies of 92.5% and 22.3% were recorded for BRSV and BHV-4, respectively. The presence of antibodies against these viruses in cattle from Ethiopia is recorded for the first time in this report. Our data suggests diseases caused by these viruses occur in Ethiopia but, perhaps because disease signs are not specific, they have not been recognized in the past.
