RUIZ-SAENZ, Julián; JAIME, Jairo  and  VERA, Víctor J. Serological prevalence and isolation of Bovine herpesvirus-1 (BHV-1) in cattle herds from Antioquia and Valle del Cauca provinces. Rev Colom Cienc Pecua [online]. 2010, vol.23, n.3, pp.299-307. ISSN 0120-0690.

Bovine herpesvirus 1 (BHV-1) causes severe economic losses. This virus has been reported in Colombia since the early 70s, and although vaccination and prevention plans have been established, it is considered one of the major constraints for the cattle industry. Our objective was to conduct a serological survey for the presence of BHV-1 in non-vaccinated beef cattle and dairy farms. A cross-sectional serological survey, sampling 316 unvaccinated individuals from six farms located in Antioquia and Valle del Cauca provinces was conducted. The serum neutralization test showed 100% sero-prevalence of BHV-1 in each herd and 75.63% overall prevalence for individuals. The prevalence for herds in Antioquia and Valle provinces was 85.51% and 69.84% respectively. By immunosuppressive therapy, viral isolations were attempted from samples of individuals with the highest neutralizing titers, obtaining isolates from both bulls and cows, indicating an enzootic state of infection and demonstrating that BHV-1 remains one of the most widely dispersed agents in the country.
