Bovine viral diarrhea virus (BVDV) is an economically important pathogen of the livestock industry worldwide. BVDV is classified into cytopathic (cp) and noncytopathic (ncp), depending on its effects on cultured cells. BVDV is known to alter the host’s immune response. Of this, major histocompatibility complex (MHC) class II molecules play a central role in the development and function of the i...
13 Weaning management of newly received beef calves with or without continuous exposure to a persistently infected bovine viral diarrhea virus pen mate: Effects on rectal temperature, peripheral blood leukocytes and serum proinflammatory cytokine concentrations. J. T. Richeson*1, E. B. Kegley1, J. G. Powell1, R. G. Schaut2, R. E. Sacco3, and J. F. Ridpath3, 1University of Arkansas, Fayetteville...
Bovine viral diarrhea virus (BVDV) causes one of the most economically important diseases in cattle, and the virus is found worldwide. A better understanding of the disease associated factors is a crucial step towards the definition of strategies for control and eradication. In this study we trained a random forest (RF) prediction model and performed variable importance analysis to identify fac...
Bovine viral diarrhea virus (BVDV) is one of the most important viral pathogens of cattle worldwide. Because of the insidious and complex nature of BVDV, laboratory diagnosis is critical in preventing and controlling BVDV infections. These same characteristics often make laboratory diagnosis challenging. A firm understanding of the disease is required to select the appropriate diagnostic strate...
BACKGROUND Infections with bovine herpesvirus 1 (BoHV-1) and bovine viral diarrhoea (BVD) virus cause diseases of cattle with a worldwide distribution. The primary objective of the present study was to describe aspects of herd-level BoHV-1 and BVDV seroprevalence (based on testing of pooled sera) and control on farms in Northern Ireland, including vaccine usage. An indirect antibody ELISA test ...
زمـیـنــه مــطــالـعــه: دو بـیـمــاری اسـهــال ویــروســی گـاوان (Bovine viral diarrhea, BVD) و رینـوتـراکئیـت عفـونـی گـاوان (Infectious bovine rhinotracheitis, IBR)، از جمله عوامل تحمیل خسارات اقتصادی قابل توجه در صنعت دامپروری ایران می‌باشد. هدف: با توجه به فقدان واکسن تولید داخل، ضروری است، اثربخشی واکسن‌های تجاری وارداتی بررسی شود. روش کار: کارآزمایی شاهددار تصادفی شده و کور با هدف تعیی...
The recently emerging atypical bovine pestiviruses have been detected in commercial foetal bovine serum (FBS) of mainly South American origin so far. It is unclear how widely the viruses are presented in commercial FBS of different geographic origins. To further investigate the possible pestivirus contamination of commercially available FBS batches, 33 batches of FBS were obtained from ten supp...

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...
