Transmission of classical swine fever virus by artificial insemination

Veterinary Microbiology, 1999
Classical swine fever (CSF) virus was introduced into an artificial insemination centre during the CSF epizootic of 1997-1998 in the Netherlands. The risk of further spread of CSF virus via contaminated semen was recognised, but could not be assessed because scientific data on this issue were not available.

Genetic variability and distribution of Classical swine fever virus

Animal Health Research Reviews, 2015
AbstractClassical swine fever is a highly contagious disease that affects domestic and wild pigs worldwide. The causative agent of the disease is Classical swine fever virus (CSFV), which belongs to the genusPestiviruswithin the familyFlaviviridae. On the genome level, CSFV can be divided into three genotypes with three to four sub-genotypes.

Phylogenetic analysis of classical swine fever virus in Taiwan

Archives of Virology, 2005
Two envelope glycoprotein (Erns and E2) regions of the classical swine fever virus (CSFV) were amplified by RT-PCR and sequenced directly from 158 specimens collected between 1989 and 2003 in Taiwan. Phylogenetic analysis of the two regions revealed a similar tree topology and the Erns region provided better discrimination than the E2 region.

Classical Swine Fever Virus

2018
Classical swine fever (CSF) caused by classical swine fever virus (CSFV), Pestivirus genus of the Flavivirdae family, is a highly contagious, multisystemic, and hemorrhagic disease of pigs and one of the most important disease in pig industry, economically and clinically. Domestic and wild pigs are the only natural reservoirs of CSFV.

Survival and inactivation of classical swine fever virus

Veterinary Microbiology, 2000
Classical swine fever virus, like many enveloped viruses, may be regarded as moderately fragile. It shows a short but variable survival time in the environment, depending on physical conditions, but may remain viable for prolonged periods in favourable circumstances as found, for example, in stored meat.

Evidence of natural recombination in classical swine fever virus

Virus Research, 2007
Classical swine fever (CSF) virus, one member of the family Flaviviridae is the pathogen of CSF, an economically important and highly contagious disease of pigs. Although homologous recombination has been demonstrated in many other members of the family, it is unknown whether there is recombination in natural populations of CSFV.

Phylogenetic comparison of classical swine fever virus in China

Virus Research, 2001
An N-terminal fragment of the E2 gene of classical swine fever (CSF) virus encoding major immunogenic sites was amplified by RT-PCR directly from 110 clinical specimens representing 109 epizootic sites during the last decade in China. Phylogenetic relationships between these viruses as well as 20 reference strains were determined by comparison of their

Prevalence of African swine fever virus and classical swine fever virus antibodies in pigs in Benue State, Nigeria

Tropical Animal Health and Production, 2017
This study investigated the prevalence of African swine fever virus (ASFV) and classical swine fever virus (CSFV) antibodies in pigs in Benue State, Nigeria. Serum samples were collected from a total of 460 pigs, including 416 from 74 piggeries and 44 from Makurdi slaughter slab.

Isolation and characterization of cytopathogenic classical swine fever virus (CSFV)

Archives of Virology, 1998
Two new classical swine fever virus (CSFV) isolates obtained from naturally infected swine were found to exhibit a cytopathogenic (cp) phenotype. According to their reactivity with monoclonal antibodies (mabs) the isolates cpBW1 and cpMVP1 were classified as antigenic types "Lothringen'92" and "Flandern'90", respectively.

Phylogenetic analysis of classical swine fever virus isolated from Taiwan

Veterinary Microbiology, 2005
By analyzing the E2 sequences of classical swine fever virus from field outbreaks in Taiwan during 1993-2001, three virus populations with distinct genotypes were determined including one historical (subgroup 3.4) and two exotic (subgroup 2.1) strains. The first subgroup 2.1 virus was isolated in 1994 and further sporadic outbreaks occurred after 1996.
