Persistent bovine viral diarrhea virus (BVDV) infection in cattle herds
Bovine viral diarrhea virus (BVDV) is a significant pathogen associated with gastrointestinal, respiratory, and reproductive diseases of cattle worldwide. It causes continuous economic losses to the cattle industry primarily due to decreased reproductive performance. The ability of virus to cross the placenta during early pregnancy can result in the birth of persistently infected (PI) calves. P...
متن کاملTransdominant inhibition of bovine viral diarrhea virus entry.
Bovine viral diarrhea virus (BVDV) is a positive-strand RNA virus and a member of the genus Pestivirus in the family Flaviviridae. To identify and characterize essential factors required for BVDV replication, a library expressing random fragments of the BVDV genome was screened for sequences that act as transdominant inhibitors of viral replication by conferring resistance to cytopathic BVDV-in...
متن کاملDetection of Bovine Viral Diarrhea Virus in Bovine Semen Using Nested-PCR
A rapid and sensitive reverse transcription polymerase chain reaction (RT-PCR) and nested-PCR were used to detect bovine viral diarrhea virus 1 (BVDV-1) in bull semen. Selected primers could amplify a part of the 5´UTR of the BVDV genome. A 294 bp DNA fragment was amplified and specificity of the results was confirmed by direct sequencing of the PCR product. Prior to RNA extraction, the seminal...
متن کاملThe effect of bovine viral diarrhea virus on bovine monocyte phenotype
Bovine viral diarrhea virus (BVDV) is an economically important pathogen of the livestock industry worldwide. BVDV is classified into cytopathic (cp) and noncytopathic (ncp), depending on its effects on cultured cells. BVDV is known to alter the host’s immune response. Of this, major histocompatibility complex (MHC) class II molecules play a central role in the development and function of the i...
متن کاملBovine viral diarrhea virus strain- and cell type-specific inhibition of type I interferon pathways.
The interaction of noncytopathogenic bovine viral diarrhea virus type 1 (BVDV-1ncp) with antigen-presenting cell (APC) subsets is of great interest due to the recent increase in severe acute BVDV outbreaks attributed to this genotype (1, 12, 13). We report the effect of a BVDV-1ncp strain (Ho916ncp [13]) causing severe acute infection on in vitro type I interferon (alpha/beta interferon [IFN/ ]...
