26. DISTRIBUIÇÃO DO DNA DOS HERPESVÍRUS BOVINO TIPOS 1 (BHV-1) E 5 (BHV-5) NO ENCÉFALO DE COELHOS DURANTE A INFECÇÃO LATENTE / DISTRIBUTION OF BOVINE HERPESVIRUS TYPES 1 (BHV-1) AND 5 (BHV-5) DNA IN THE BRAIN OF RABBITS DURING LATENT INFECTION
O herpesvírus bovino tipo 5 (BHV-5) é um importante agente etiológico de meningoencefalite em bovinos e estabelece infecção latente em seus hospedeiros, principalmente nos gânglios dos nervos sensoriais. No entanto, a colonização de áreas profundas do cérebro com DNA viral pode ter implicações importantes na patogenia da infecção pelo BHV-5 ap�

27. Production and characterization of monoclonal antibodies to a Brazilian bovine herpesvirus type 5
Antigens of a bovine herpesvirus type 5 (BHV-5), isolated from a cow with a neurological infection in Rio Grande do Sul State, Brazil, were used to immunize BALB/c mice to produce monoclonal antibodies (mAbs). Eleven hybridomas secreting mAbs directed at BHV-5 antigens were obtained after two fusions and screening of 356 hypoxanthine-aminopterin-thymidine-re

28. 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

29. Replication of Bovine Herpesvirus Type 4 in Human Cells In Vitro
A reference strain (Movár 33/63) of bovine herpesvirus type 4 (BHV-4) was inoculated into 14 different human cell lines and five primary cell cultures representing various human tissues. BHV-4 replicated in two embryonic lung cell lines, MRC-5 and Wistar-38, and in a giant-cell glioblastoma cell culture. Cytopathic effect and intranuclear inclusion bodies w

30. Short repeats cause heterogeneity at genomic terminus of bovine herpesvirus 1.
Analysis of the genomes of different bovine herpesvirus 1 strains revealed a UL terminal HindIII fragment differing in size (from 2.4 to 2.8 kilobases). This fragment polymorphism occurred in the DNA of a wild-type isolate, in highly passaged, apathogenic tissue culture derivatives, and in plaque-purified substrains. This heterogeneity was due to variations

31. The bovine herpesvirus 1 maturational proteinase and scaffold proteins can substitute for the homologous herpes simplex virus type 1 proteins in the formation of hybrid type B capsids.
We determined the nucleotide sequence of a 3.5-kb region of the bovine herpesvirus 1 (BHV-1) genome which contained the complete BHV-1 homologs of the herpes simplex virus type 1 (HSV-1) UL26 and UL26.5 genes. In HSV-1, the UL26 and UL26.5 open reading frames encode scaffold proteins upon which viral capsids are assembled. The UL26-encoded protein is also a

32. A Mutation in the Latency-Related Gene of Bovine Herpesvirus 1 Inhibits Protein Expression from Open Reading Frame 2 and an Adjacent Reading Frame during Productive Infection
The latency-related (LR) gene of bovine herpesvirus 1 (BHV-1) is abundantly expressed during latency. A mutant BHV-1 strain that contains three stop codons at the 5′ terminus of the LR gene (LR mutant) does not reactivate from latency. This study demonstrates that the LR mutant does not express open reading frame 2 or an adjacent reading frame that lacks a

33. Localization of cis-acting sequences in the latency-related promoter of bovine herpesvirus 1 which are regulated by neuronal cell type factors and immediate-early genes.
Bovine herpesvirus 1 (BHV-1) establishes a latent infection in sensory ganglionic neurons of cattle. During a latent infection, a single latency-related (LR) transcript is expressed. This observation suggested that DNA sequences in the LR promoter are positively regulated by neural cell type factors. The regulation of the LR gene was examined in neural cells

34. A neutrophil-derived antiviral protein: induction requirements and biological properties.
Polymorphonuclear neutrophilic granulocytes (PMN) have been implicated as playing a role in antiviral defense. In addition to having phagocytic and cytotoxic activities, PMN may produce an antiviral substance with interferon (IFN)-like activity. The product, for which the name polyferon (PF) has been coined, is produced upon direct encounter of PMN with bovi

35. Detection of Bovine Herpesvirus Type 1 in Blood from Naturally Infected Cattle by Using a Sensitive PCR That Discriminates between Wild-Type Virus and Virus Lacking Glycoprotein E
In the present study, we report for the first time on the detection of bovine herpesvirus type 1 (BHV-1) in whole-blood samples derived from naturally infected cattle. Sensitive PCR assays specific for glycoprotein B (gB), gC, and gE of BHV-1 allow the detection of one BHV-1 DNA copy in 105 to 107 peripheral blood leukocytes (PBLs). The incidence of BHV-1-po

36. A Glycine-Rich Bovine Herpesvirus 5 (BHV-5) gE-Specific Epitope within the Ectodomain Is Important for BHV-5 Neurovirulence†
The bovine herpesvirus 5 (BHV-5) gE ectodomain contains a glycine-rich epitope coding region (gE5 epitope), residues 204 to 218, that is significantly different from the corresponding gE region of BHV-1. Deletion of the gE epitope significantly reduced the neurovirulence of BHV-5 in rabbits. Pulse-chase analyses revealed that the epitope-deleted and wild-typ
