Glycoprotein D (gD) is the major structural protein of infectious bovine rhinotracheitis virus (IBRV). It can induce both humoral and cellular immunity thus it is a preferable protein for IBR diagnostic reagent. Regarding to DNAstar analysis, the major antigenic region of the gD fragment was amplified by PCR using the IBRV genomic DNA as a template, and subsequenly constructed into the recombin...

Bovine viral diarrhea- and Border disease viruses of sheep belong to the highly diverse genus pestivirus of the Flaviviridae. Ruminant pestiviruses may infect a wide range of domestic and wild cloven-hooved mammals (artiodactyla). Due to its economic importance, programs to eradicate bovine viral diarrhea are a high priority in the cattle industry. By contrast, Border disease is not a target of...

Detection of bovine viral diarrhea virus in 143 blood samples by virus isolation in cell culture and flow cytometry was performed. The material included 37 samples later shown to originate from persistently infected cattle. Thirty-three samples were positive by virus isolation, and all 37 samples were positive by the flow cytometric assay.

ABSTRACT: This report described the clinical and pathological aspects of open spina bifida diplomyelia along with multiple congenital malformations in a Texel lamb. Clinically, paresis thoracic limbs, paralysis pelvic limbs cutaneous opening lumbosacral region were observed. At necropsy, there was focally extensive disruption skin associated an absence dorsal portions vertebrae. Additionally, l...

In our previous study, we genetically analyzed bovine viral diarrhea viruses (BVDVs) isolated from 2000 to 2006 in Japan and reported that subgenotype 1b viruses were predominant. In the present study, 766 BVDVs isolated from 2006 to 2014 in Hokkaido, Japan, were genetically analyzed to understand recent epidemics. Phylogenetic analysis based on nucleotide sequences of the 5'-untranslated regio...
