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 post-inoculation (group A, N = 8) or sub...

We have shown previously that BHV-1 infection activates Erk1/2 signaling. Here, we show that BHV-1 provoked an early-stage transient and late-stage sustained activation of JNK, p38MAPK and c-Jun signaling in MDBK cells. C-Jun phosphorylation was dependent on JNK. These early events were partially due to the viral entry process. Unexpectedly, reactive oxygen species were not involved in the late...

Polymerase chain reaction (PCR) technique was applied to detect BHV-1 in bovine semen inoculated with BHV-1. The technique was found to be 10(6) times more sensitive than a non-isotopic dot-blot hybridization method in detecting viral genomic DNA. Of the three primer pairs used, the one chosen from glycoprotein gC appeared to be most sensitive as it could detect up to 0.01 TCID50 of BHV-1 in th...

Bovine respiratory disease (BRD) is the leading cause of morbidity and mortality in feedlot cattle. herpesvirus-1 (BHV-1) one main culprits BRD; however, research on BHV-1 hampered by lack suitable models for infection drug testing. In this study, we established a novel bovine tracheal organoid culture grown basement membrane extract type 2 (BME2) matrix compared it with air–liquid interface (A...

Glycoprotein B (gB) of bovine herpesvirus 1 (BHV-1) is essential for BHV-1 replication and is required for membrane fusion processes leading to virus penetration into the target cell and direct spreading of BHV-1 from infected to adjacent noninfected cells. Like many of the herpesvirus gB homologs, BHV-1 gB is proteolytically processed by furin, an endoproteinase localized in the trans-Golgi ne...

AIM Objective of the present study was to isolate bovine herpes virus Type 1 (BHV-1) from semen of infected bull and to adapt it onto embryonated eggs and Madin-Darby bovine kidney (MDBK) cell line. Further, the virus was identified by agar gel immunodiffusion (AGID) test. MATERIALS AND METHODS Semen samples were collected from five BHV-1 positive bulls previously confirmed for the presence o...
