Effects of formalin inactivation on bovine herpes virus-1 glycoproteins and antibody response elicited by formalin-inactivated

It was concluded that B11-41 was identified as a BHV-4 that belongs to the American group. Sequence comparison indicated a BHV-1 open reading frame having a 60% similarity to the HSV vhs sequence. Few cells become elongated when compared with uninfected controls. Few cells become elongated when compared with uninfected controls. rounding of cells with shrinkage, followed by aggregation or clumping of cells which progressed rapidly and appeared as “bunch of grapes” at 72 h post inoculation. In addition, the LR encoded microRNAs inhibit viral transcription and apoptosis. He has published number of papers in reputed international and national journals and has a vast experience in the arena of BHV-I virus.

1–12) for study of primary (acute) infection and group 2 (calf Nos. Control measures include ensuring the milking machine is in full working order with no faults e.g. When injected directly into the bulb, both viruses were equally neurovirulent, and they were transported retrogradely to areas connected to the bulb. Links to PubMed are also available for Selected References. Links to PubMed are also available for Selected References. The gEdelta3.1IBR virus contained a deletion in the viral gE gene-coding sequences where a stable chimeric reporter (beta-gal) gene was inserted. These results indicate that BoHV-1 gK and UL20 may function in a similar manner to other alphaherpesvirus orthologues specified by HSV-1, PRV and EHV-1.

Humoral and cellular immune responses directed against the BoHV-1 antigens were evaluated after oral or intranasal administration of the recombinant bacteria. These results indicate that these viruses failed to infect zona-intact oocytes or embryos during in vitro maturation and culture. The results show that the quality of most laboratories appeared to be adequate, but that one laboratory performed considerably below an acceptable level of quality. To further localize the neutralizing epitopes, synthetic peptides corresponding to these regions in the BHV-1 gD ORF were tested for their capacity to block monoclonal antibody neutralization of BHV-1 infectivity. Using PCR, 11 (10.7%) out of 103 samples were found to be positive. Vaccinia-gIV-infected targets were lysed predominantly when PBMC were stimulated by fixed infected fibroblasts, whilst PBMC stimulated by UV-inactivated virus lysed mostly vaccinia-gIII-infected targets. Also in the isolate 554 at least a half of the UL24 genes were found to be altered independently of the MOT used.

BoHV-4 as a strange herpesvirus has several features which are not characteristic of other herpesviruses, such as several latency sites, persistence in serum, dividing cells necessary for virus replication, and the wide host range. Use as a quality control for PCR and/or extraction yield. In the dependency, among other factors, of the viral subtype may determine respiratory, reproductive, nervous and systemic signals. BVDv and BoHV-1 are highly contagious cattle viruses, exhibit a worldwide distribution and are listed as notifiable diseases by the OIE (Office International des Epizooties). IBR causes considerable losses for the cattle industry worldwide, and BRDC is estimated to cost the U.S. Two types of these microcapsules-impregnated and loaded with the inhibitor-were used in virus infectious studies.

Bull. We have cloned a complementary DNA (cDNA) encoding bovine herpes virus-1 (BHV-1) glycoprotein 1 (gpI) into the eucaryotic expression vector, pZipNeo SVX1. The four glycoproteins were all coprecipitated by a neutralizing monoclonal antibody and were probably involved as target antigens in virus neutralization. The objectives of the present study were to explore the interaction, tropism and outcomes of BoHV-4 challenge of endometrial stromal and epithelial cells. Freshly isolated or overnight cultured bovine peripheral blood mononuclear (PBM) cells lysed bovine herpes virus 1 (BHV-1)-infected allogeneic and xenogeneic target cells but not non-infected target cells. and  CHOWDHURY, S.I.. Microscopic examination of GBK BHV-1 infected cells revealed peroxidase activity represented by red-brown granular deposits in the nucleus and cytoplasm.

Non-major histocompatibility complex (MHC) restricted cytotoxicity is an important part of the immune reaction mounted in response to bovine herpes virus type 1 (BHV-1) infection.

The aim of this observational cohort study was to investigate the potential economic effect of sub-clinical Bovine Herpes Virus 1 (BoHV-1) infection in a commercial UK dairy herd in terms of milk yield depression.

The present work aimed to observe the infection pattern of Bovine herpes virus-1 (BoHV-1) in dairy cattle with reproductive problems in Sudan.
