RESUMO
Bovine encephalitis herpesvirus, or bovine herpesvirus type 5 (BoHV-5), a member of the family Herpesviridae, subfamily Alphaherpesvirinae, is long recognized as the causative agent of bovine herpesvirus encephalitis. The disease caused by BoHV-5 is characterized by signs of nervous impairment, consequent to non-suppurative meningoencephalitis. Although bovine herpetic encephalitis is a rare event in herds from the Northern Hemisphere, BoHV-5 infections are an important cause of central nervous system disease in cattle in Brazil and Argentina. Recovery of animals from clinical illness has been documented before, both in naturally infected animals and experimentally infected individuals.[...](AU)

Amostras de herpesvírus bovinos (BHV) tipo 1 (Virus da Rinotraqueíte Infecciosa Bovina/Vulvovaginite Pustular Infecciosa; BHV-1) e tipo 5 (Herpesvírus da Encefalite Bovina; BHV-5) tiveram seu perfil de reatividade analisado em testes de imunoperoxidase frente a um painel composto por cinco anticorpos monoclonais (AcM) produzidos contra antígenos de BHV-1. Um dos AcM reconheceu todas as amostras de BHV examinadas. Os quatro AcM restantes reconheceram somente amostras de BHV-1. Todas as amostras isoladas de casos de encefalites (BHV-5) apresentaram um padrão de reação distinto daquelas isoladas de outros síndromes associados à infecção pelo BHV-1. Os resultados obtidos indicam que os AcM avaliados permitem a diferenciação entre amostras de BHV-1 e BHV-5, havendo perfeita correlação entre os quadros clínicos observados com os perfis de reatividade obtidos in vitro
