The genesis for this special issue on pestiviruses was a joint meeting on pestiviruses organized by the US BVDV Symposia Committee and the European Society for Veterinary Virology that was held October 14 and 15, 2014 in Kansas City, MO. The theme of the meeting was "Pestiviruses: Old enemies and new challenges". The impetus for this joint effort was the recognition that regional approaches to ...
Amphipathic α-helices of exchangeable apolipoproteins have shown to play crucial roles in the formation of infectious hepatitis C virus (HCV) particles through the interaction with viral particles. Among the Flaviviridae members, pestivirus and flavivirus possess a viral structural protein Erns or a non-structural protein 1 (NS1) as secretory glycoproteins, respectively, while Hepacivirus inclu...
Bovine viral diarrhoea virus (BVDV) isolates infect cultured Madin-Darby bovine kidney (MDBK) cells as efficiently as sheep kidney cells. In contrast, border disease virus (BDV) propagates poorly in MDBK cells but infects sheep cells very efficiently. The envelope glycoprotein E2 has been shown to be essential for virus infectivity. To explore the potential role of E2 in pestivirus host range i...
Although most commonly associated with the infection of domestic livestock, the replication of pestiviruses, in particular the two species of bovine viral diarrhea virus (BVDV), occurs in a wide range of free ranging cervids including white-tailed deer, mule deer, fallow deer, elk, red deer, roe deer, eland and mousedeer. While virus isolation and serologic analyses indicate that pestiviruses a...
The genus pestivirus in the Flavivirus family is comprised of single-stranded RNA viruses that infect domestic and wildlife hosts. The " classic " pestivirus species, bovine viral diarrhea virus type 1 (BVDV1), bovine viral diarrhea virus type 2 (BVDV2), border disease virus (BDV), and classical swine fever virus (CSFV) were first detected in domestic animals and early differentiation of pestiv...
In 2010, a HoBi-like pestivirus was isolated from clinically affected calves in Italy. This European virus reproduced a milder form of disease under experimental conditions and was genetically related to previously reported HoBi-like strains. Isolation of this novel virus from a clinical outbreak may have implications for cattle health and prophylactic programs.
Bovine viral diarrhea viruses (BVDV) are members of the Pestivirus genus within the family Flaviviridae. Based on antigenic and nucleotide differences, BVDV are classified into two recognized species, BVDV-1 and BVDV-2. More recently, a new putative pestivirus species, tentatively called "HoBi-like", has been associated with bovine viral diarrhea. HoBi-like viruses were first identified in feta...
In Egypt, bovine virus diarrhoea-mucosal disease (BVD-MD) was initially detected as the result of a serological survey of cattle and sheep, using the serum neutralisation test. In 1970, the causal pestivirus was isolated from bovine calves and buffalo calves with pneumonia and enteritis. Mixed viral infections were also prevalent. Cases of immune tolerance were identified. The Egyptian industry...
