RESUMO: Em um levantamento sobre doenças de bovinos, revisamos os protocolos de 5.083 necropsias de bovinos realizadas no período de janeiro de 1995 a dezembro de 2018 e arquivados no Laboratório de Anatomia Patológica (LAP) da Universidade Federal de Mato Grosso do Sul (UFMS). Essas necropsias foram realizadas pelos veterinários e professores do LAP-UF

2. Identificação de herpesvírus bovino em amostras de cérebro / Identification of bovine herpesvirus in brain samples
Herpetic meningoencephalitis is an infection of the central nervous system caused by bovine herpesvirus 5 (BoHV-5) despite BoHV-1 also being associated with this pathology. The course of the disease is usually fatal. Meningoencephalitis has caused significant economic burden to the Brazilian cattle industry due to its high mortality rate, especially in young

3. Selection and characterization of brivudin resistant bovine herpesvirus type 5
Bovine herpesvirus type 5 (BoHV-5) is the agent of meningoencephalitis, an important disease of cattle in South America. The neuropathogenesis of BoHV-5 infection is poorly understood and most previous research focused on the role of envelope glicoproteins in neurovirulence. Thymidine kinase (TK) is a viral enzyme necessary for virus replication in neurons a

4. A bovine herpesvirus 5 recombinant defective in the thymidine kinase (TK) gene and a double mutant lacking TK and the glycoprotein E gene are fully attenuated for rabbits
Bovine herpesvirus 5 (BoHV-5), the agent of herpetic meningoencephalitis in cattle, is an important pathogen of cattle in South America and several efforts have been made to produce safer and more effective vaccines. In the present study, we investigated in rabbits the virulence of three recombinant viruses constructed from a neurovirulent Brazilian BoHV-5 s

5. Genotyping of S. agalactiae strains isolated from human, bovine and fish and their virulence potential to Nile tilapia / Genotipagem de Streptococcus agalactiae isolados de seres humanos, bovinos e peixes e seu potencial de virulÃncia para tilÃpia do Nilo
Streptococcus agalactiae (Lancefield group B; GBS) is an important pathogen to human, bovine and fish causing neonatal sepsis, mastitis and meningo-encephalitis, respectively. The objective of this study was to characterize by PFGE S. agalactiae isolated from fish (n=27), bovine (n=9) and human (n=11) and to investigate the virulence of bovine, fish and huma

6. Infecção experimental de coelhos com o isolado mutum de herpesvirus bovino 5 (BoHv-5)
Bovine herpesvirus 5 (BoHV-5) is an alphaherpesvirus associated with meningoencephalitis, an usually fatal disease and highly prevalent in South America. In this study, we infected rabbits with a Brazilian BoHV-5 strain, named Mutum, isolated from a bovine with spinal cord symptoms, uncommon for this illness. Six animals were inoculated intranasally and two

7. EPIDEMIOLOGY, CLINICAL SIGNS AND DISTRIBUTION OF ENCEPHALIC LESIONS IN CATTLE AFFECTED BY MENINGOENCEPHALITIS CAUSED BY BOVINE HERPESVIRUS-5 (BoHV-5) / EPIDEMIOLOGIA, SINAIS CLÍNICOS E DISTRIBUIÇÃO DAS LESÕES ENCEFÁLICAS EM BOVINOS AFETADOS POR MENINGOENCEFALITE POR HERPESVÍRUS BOVINO-5 (BoHV-5)
São descritos sete surtos e um caso isolado de meningoencefalite por herpesvírus bovino-5 (BoHV-5) em bovinos no Rio Grande do Sul entre 2002-2004. Foram afetados bovinos de 1-18 meses, de diversas raças e ambos os sexos. A maior freqüência foi observada em bovinos recém-desmamados e submetidos a outros fatores de estresse. Nesses surtos, de uma popula

8. Dexamethasone-induced reactivation of bovine herpesvirus type 5 latent infection in experimentally infected rabbits results in a broader distribution of latent viral DNA in the brain
Bovine herpesvirus type 5 (BHV-5) is a major agent of meningoencephalitis in cattle and establishes latent infections mainly in sensory nerve ganglia. The distribution of latent BHV-5 DNA in the brain of rabbits prior to and after virus reactivation was studied using a nested PCR. Fifteen rabbits inoculated intranasally with BHV-5 were euthanized 60 days pos

Rabbits have been used as animal models to study the pathogenesis of neurological infection by bovine herpesvirus type 5 (BHV-5), an important agent of meningoencephalitis in cattle. The olfactory system has been implicated as the main pathway for the virus to reach the brain after replication in the nasal mucosa. To investigate the role of the olfactory rou

10. Comparison of Bovine herpesvirus type 5 (BoHV-5) isolates as vaccine candidates / Comparação de isolados de Herpesvírus bovino tipo 5 (BoHV-5) como candidatos à vacina
O herpesvírus bovino tipo 5 (BoHV-5) é o agente etiológico da menigoencefalite bovina que apresenta alta morbidade em bovinos jovens. Devido à similaridade na morfologia do virion, efeito citopático na cultura de células e propriedades antigênicas, o BoHV-5 foi classificado erroneamente como herpesvírus bovino tipo 1 (BoHV-1). Este vírus é respons�

11. Detecção de herpesvírus bovino 5 (BoHV-5) em bovinos do Sudeste Brasileiro
This paper reports the detection of bovine herpesvirus type 5 (BoHV-5) by a specific nested PCR assay. Samples were collected from the central nervous system (CNS) of cattle from Minas Gerais and São Paulo States, Brazil. All animals died presenting neurological symptoms. Nineteen frozen CNS samples analyzed had been previously tested by fluorescence antibo

12. Genome of Bovine Herpesvirus 5
Here we present the complete genomic sequence of bovine herpesvirus 5 (BHV-5), an alphaherpesvirus responsible for fatal meningoencephalitis in cattle. The 138,390-bp genome encodes 70 putative proteins and resembles the α2 subgroup of herpesviruses in genomic organization and gene content. BHV-5 is very similar to BHV-1, the etiological agent of infectious
