An investigation into the transmission and control of pestivirus in sheep in Australia

Australian Veterinary Journal, Volume 102, Issue 3, Page 60-66, March 2024.
Border disease virus (BDV) is a member of the pestivirus genus that primarily affects sheep, causing reproductive losses through abortion, still births and the birth of weak lambs. The key characteristic of this disease is the birth of persistently infected (PI) lambs which, after surviving transplacental infection, are born antibody negative, yet ...

Persistent Infection Caused by Hobi-Like Pestivirus [PDF]

Journal of Clinical Microbiology, 2013
ABSTRACT A calf persistently infected by Hobi-like pestivirus was monitored for about 6 months, displaying clinical signs typical of bovine viral diarrhea virus persistent infection and shedding the virus through all body secretions, with maximal titers detected in urine. This report provides new insights into the pathogenesis of the emerging

Efficient generation of recombinant RNA viruses using targeted recombination-mediated mutagenesis of bacterial artificial chromosomes containing full-length cDNA [PDF]

, 2013
BACKGROUND: Infectious cDNA clones are a prerequisite for directed genetic manipulation of RNA viruses. Here, a strategy to facilitate manipulation and rescue of classical swine fever viruses (CSFVs) from full-length cDNAs present within bacterial ...

Sporadic bovine encephalopathy caused by Chlamydia pecorum secondary to bovine viral diarrhoea virus infection in calves in South Australia

Australian Veterinary Journal, Volume 102, Issue 3, Page 80-86, March 2024.
Background Despite bovine viral diarrhoea virus and Chlamydia pecorum being important endemic diseases of cattle, there are limited reports of theirco‐occurrence. Case report Several 12–18‐week‐old, weaned Hereford calves presented with ill‐thriftiness and neurological signs on a mixed cattle and sheep farm in South Australia in July 2021.

Evolutionary origin of the Jiv90 gene of Pestivirus

Infection, Genetics and Evolution, 2004
Phylogenetic analyses were used to test the hypothesis that the Jiv90 insert in the genomes of Pestivirus species originated by horizontal transfer from their hosts (mammals in the order Artiodactyla). The results supported this hypothesis because the Jiv90 insert clustered with the corresponding domains of mammalian Jiv proteins and closer to ...

Characterization of an Autonomous Subgenomic Pestivirus RNA Replicon [PDF]

Journal of Virology, 1998
ABSTRACTAs an initial approach to define the requirements for the replication of bovine viral diarrhea virus (BVDV), a member of theFlaviviridaefamily with a positive-strand RNA genome, full-length genomic and subgenomic RNAs were originated by in vitro transcription of diverse BVDV cDNA constructs and transfected into eucaryotic host cells.

Isolation and Full-Length Sequence Analysis of a Pestivirus from Aborted Lamb Fetuses in Italy

Viruses, 2019
Pestiviruses are distributed worldwide and are responsible for a variety of economically important diseases. They are not very host-specific, and thus sheep can be infected by well-known pestiviruses like bovine viral diarrhea virus (BVDV) and border ...

Genetically distinct pestiviruses pave the way to improved classical swine fever marker vaccine candidates based on the chimeric pestivirus concept

Emerging Microbes and Infections, 2020
Classical swine fever (CSF) is one of the most important viral diseases of pigs. In many countries, the use of vaccines is restricted due to limitations of subunit vaccines with regard to efficacy and onset of protection as well as failure of live ...

Integration of Planova filters in manufacturing processes of biologicals improve the virus safety effectively: A review of publicly available data

Biotechnology Progress, Volume 40, Issue 1, January/February 2024.
Abstract The capacity to remove viruses by Planova filters produced by Asahi Kasei, primarily by small virus‐retentive filters, were compiled from data in peer‐reviewed publications and, partly, publicly available data from presentations at conferences (Planova workshops).
