Serological evaluation of bovine herpesvirus 1 and 5 in cattle-breeding systems on Colombia’s high plains
Journal Title: Revista MVZ Cordoba - Year 2016, Vol 21, Issue 2
Abstract
Objective. The aim of this study was to determine the presence of Bovine herpesvirus – 1 (BoHV-1) and Bovine herpesvirus 5 (BoHV-5) neutralizing antibodies in herds on the Colombian high plains and their correlation with the level of cross-protection against both herpesviruses. Materials and methods. This study was carried out on cattle farms located around the towns of Puerto López and Puerto Gaitán in Colombia’s Meta department. Sampling was made by convenience. Twenty-three farms were involved in the study; 488 sera samples were taken by random sampling. Virus neutralization test were performed according to the protocols of the OIE. Each serum was evaluated independently for each virus, BoHV-1 and BoHV-5. Results. The serological test confirmed the presence of BoHV-1 and BoHV-5 infections in the Colombian bovine population in 100% and 73.9% respectively. However, cross-reaction for both viruses was not evident in all farms evaluated. Conclusions. Alpha-herpesviruses are amongst the most significant infectious agents affecting cattle. Bovine herpesvirus 1 (BoHV-1) is found throughout the whole world and is endemic in Colombian bovine population, whereas bovine herpesvirus 5 (BoHV-5) has limited geographical distribution, mainly being reported in South-America (Brazil and Argentina), and we also confirmed the presence of BoHV-5 in Colombia.
