Resumo: 	Bovine herpesvirus 5 (BoHV-5) is an important cause of meningoencephalitis in young and adult cattle. The multiple etiology of neurological disturbances in cattle makes the quick and conclusive diagnosis of BoHV-5 infection important for animal and public health, mainly because of herbivore rabies that is endemic in Brazilian cattle herds. The objective of this retrospective study was to use a multiplex-polymerase chain reaction (multiplex-PCR) for BoHV-5 and BoHV-1 glycoprotein C gene detection from stored central nervous system (CNS) tissue fragments of cattle with neurological clinical signs. Forty-seven frozen CNS samples of young and adult cattle from 31 herds in three Brazilian geographical regions (South, Southeast, and Center-west) were evaluated. Eighteen (38.3%) of these CNS samples were BoHV-positive by virus isolation in cell culture. By multiplex-PCR 30 (63.8%) CNS samples were BoHV-5 positive. All 18 positive samples by virus isolation were confirmed as BoHV-5 by the multiplex-PCR, that provided a increase of 25.5% (12/47) in the BoHV-5 diagnosis rate. BoHV-1 was not detected in any CNS sample. This retrospective study demonstrated the wide regional distribution of BoHV-5 infection in Brazilian cattle herds since positive results were obtained in CNS samples of cattle with neurological disease from Paraná, São Paulo, Minas Gerais, Mato Grosso, and Mato Grosso do Sul States.
