Molecular genetics of pestiviruses
Comparative Immunology, Microbiology and Infectious Diseases, 1992Recent developments in understanding the molecular genetics of pestiviruses are reviewed. The genomic RNA of several pestiviruses has been molecularly cloned and sequenced. The genetic organization of the viral protein coding region has been refined, and the complete complement of virus-encoded proteins has been elucidated.

The Molecular Biology of Pestiviruses
2015Pestiviruses are among the economically most important pathogens of livestock. The biology of these viruses is characterized by unique and interesting features that are both crucial for their success as pathogens and challenging from a scientific point of view.

Diaplacental infections with ruminant pestiviruses
1991Pestiviruses are capable of causing diaplacental infections. Maternal viremias are important for localizing virus in the ruminant placentome. Placental lesions occur with cytopathic BVDV and noncytopathic BDV. The ruminant fetus is very susceptible to pestivirus infections once the virus crosses the placenta because the fetus is 1) agammaglobulinemic ...

Thermal and pH stability of pestiviruses.
Revue scientifique et technique (International Office of Epizootics), 1993Three strains/isolates of hog cholera virus (HCV) and two strains/isolates each of cytopathogenic (cp) and non-cytopathogenic (ncp) biotype of bovine virus diarrhoea virus (BVDV) were each exposed to pH 3, 3.5 and 4 at 4 degrees C, 21 degrees C and 37 degrees C in a number of combinations.

The genetic basis for cytopathogenicity of pestiviruses
Veterinary Microbiology, 2000Two biotypes of pestiviruses, cytopathogenic (cp) and noncp viruses, can be distinguished by their effects on tissue culture cells. Identification of cp bovine viral diarrhea virus (BVDV) has been frequently reported since antigenically closely related noncp and cp BVDV can be isolated from cattle with fatal mucosal disease (MD) and are called a virus ...

Genetic comparison of ovine and bovine pestiviruses
American Journal of Veterinary Research, 1990SUMMARY Viral rna oligonucleotide fingerprinting was used to compare genetic relationships among pestiviruses originating from ovine or bovine host species. Ovine pestiviruses, including reference border disease virus and 2 border disease isolates originating from natural pestivirus infections of sheep, appeared to have a more distant genetic ...

Genetic diversity of ruminant pestiviruses from Spain
Virus Research, 2003The genetic diversity of ruminant pestiviruses from Spain was investigated by sequencing analysis of the 5' non-coding region (5'NCR) from 10 ovine and 41 bovine samples collected along 4 years (1999-2002) from different farms. The 5'NCR amplicons generated by a one-tube RT-PCR using primers 324/326 were sequenced and phylogenetically analyzed.

Genetic typing of pestiviruses from New Zealand
New Zealand Veterinary Journal, 1998To investigate the genetic type of 20 pestiviruses collected from New Zealand over the period 1967-97.The pestiviruses were genetically typed by the sequencing of polymerase chain reaction (PCR) products. The primers selected were from the 5'-untranslated region (5'-UTR) of the pestivirus genome and consistently amplified a 288 bp fragment from all ...

Genetic heterogeneity of pestiviruses of ruminants in Switzerland
Preventive Veterinary Medicine, 2005We have genetically analyzed ruminant pestiviruses. All >150 bovine viral diarrhea (BVD) viruses isolated from cattle in Switzerland belonged to genotype 1, with subgenogroups e, h, k and b found in decreasing frequency. To date, representatives of subgenogroup k have been detected in Switzerland only.

Assembly and maturation of pestiviruses
2008The genus Pestivirus belongs to the family Flaviviridae together with the genera Hepacivirus and Flavivirus. Members of the genus Pestivirus are bovine viral diarrhea viruses (BVDV-1 and BVDV-2), classical swine fever virus (CSFV) and border disease virus (BDV), all of which have a significant economic impact on farming worldwide.
