Abstract

Infectious bovine rhinotracheitis (IBR) which is caused by bovine herpesvirus-1 (BHV-1) is poorly documented in Sub-Saharan Africa. In Cameroon, there is no previous report available on prevalence rate of IBR infections in cattle. In the present study, the serosurveillance of IBR infection was carried out in 252 randomly selected zebu cattle in small holder livestock farms from 7 subdivisions of the Vina Division using an indirect ELISA. Antibodies against BHV-1  were present in the Zebu Gudali cattle indicating the past or present infection of the animals with BHV-1. The seropositivity rate varied from 11.11% in Ngaoundere to 22.22% in Ngangha sub-division and the highest prevalence of 38.89% was recorded in Nyambaka. The overall relative prevalence rate was 16.16%. The older age group animals (>3-10 years) had a significantly higher (p < 0.05) seroprevalence than those in the younger age group (1-3 years). No significant difference (p>0.05) could be observed in prevalence rate between male and female animals. These epizootiological values, including data on the virulence of local circulating strains of  IBR virus, need to be generated for cattle producing areas in the country and considered in the planning of cattle disease control programmes.
