Book Description
The pestiviruses encompass some of the most economically important viral infections in the cattle, swine, and sheep industries worldwide. Discovered more than 70 years ago, bovine viral diarrhea virus (BVDV) and classical swine fever virus (CSFV) were long the main concern, but many new pestiviruses have emerged in recent years, which may also present additional threats to biosecurity and food safety. This issue brings together contributions from multiple disciplines – virology, immunology, veterinary clinical medicine, epidemiology, and pathology – on the subject of BVDV and related pestiviruses, and cover host–virus interactions, virus–cell interactions, cross-species transmission as well as the role of wildlife species as reservoirs of some of the pestiviruses.

Book Description
For almost 60 years, continual research on the subject of Bovine Viral Diarrhea (BVD) has raised as many questions as that research has answered. This common disease continues to cause sickness, death, abortion and fetal anomalies despite the millions of vaccination doses used each year to prevent its spread. Written by international experts on the subject of the BVD virus, BVDV: Diagnosis, Management and Control includes the latest information on BVD and outlines methods of diagnosis, management and control. Researchers, academics, and large animal practitioners will find this book an invaluable and irreplaceable resource for understanding and controlling outbreaks of BVD.

Book Description
Persistent infection (PI) with Bovine Viral Diarrhea Virus (BVDV) is a major source of economic loss for the livestock industry. Persistent infection occurs when a dam is exposed to the virus during 42 to 125 days of gestation and the virus is passed to the fetus without an adaptive immune response. These PI calves serve as continuous sources of infection to others. The identification of differences in expression of gene networks and/or genetic markers associated with infection could assist in the development of novel strategies to prevent, control, or treat BVDV. To examine the host response to PI, RNA-Seq data were obtained from blood of cattle naturally infected and PI with BVDV strains 1a (n=10), 1b (n=8), and 2 (n=8). Additional data were collected from two comparison groups, a high exposure group with one positive test for the virus that were later confirmed negative for PI (n=9), and an unexposed group from a closed herd (n=10). Sequencing on an Illumina NextSeq resulted in 58 million stranded paired-end reads per animal which were aligned to the UMD3.1 bovine genome. With 86% of the reads aligning and the quantification of 22,915 transcripts, differential expression analyses revealed there were no significant differentially expressed transcripts between the strain subtypes and among the strains of PI cattle. There were 1,032 differentially expressed transcripts between the PIs and the high exposure group; this is the comparison that was focused on in further analyses. The differential expression data were examined for gene network relationships. The top significant canonical pathways represented by the expression data were interferon signaling and activation of interferon response factors by cytosolic pattern recognition receptors. There were significant predictions of decreased replication of viruses and decreased risk of viral infection for the BVDV-PIs. These results suggest that the BVDV-PIs may have an innate immune response to BVDV since the directionality of their gene expression supports the presence of a viral infection when compared to high exposure animals.

Book Description
REBHUN'S DISEASES OF DAIRY CATTLE, 2nd Edition is your all-in-one guide to bovine disease management. With thorough, up-to-date coverage of differential diagnosis methods, surgical and therapeutic treatment options, and prevention strategies, it provides vital information for battling bovine diseases in both dairy and non-dairy cattle. The book is organized by body system for quick, convenient reference, and this new edition meets the growing need for management of both diseases of individual cows and problems affecting whole herds. Individual case presentations provide a valuable tool for differential diagnosis. Practical overviews for procedures such as blood transfusion, abdominal paracentesis, and ECG give you reliable support for some of the most common procedures in bovine care. Body systems organization makes diagnosis easier and more effective by isolating system-specific diseases and conditions. Full-color design and over 200 new photographs depict disease processes in realistic clarity and ensure the most accurate diagnosis and treatment. Emphasis on herd health addresses the dairy industry's increased concern over population medicine. Expanded coverage of lameness highlights key problem areas in bovine feet. Revised drug usage recommendations and legal considerations present the most current information in these critical areas to help you prevent dangerous or costly errors. Additional public health/safety considerations identify diseases that pose a substantial public threat and detail special measures for related care of dairy cattle. New, innovative DVD features real-time videos of neurologic case studies, ultrasound and endoscopy procedures, and imaging techniques that familiarize you with the latest technological equipment and protocols. Features coverage of the latest treatment innovations including antibiotic residue testing, care of individual metabolic disease, troubleshooting, and much more.
