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 کاملAntigenic differences between a field isolate and vaccine strains of bovine viral diarrhea virus.
Antigenic diversity among the bovine viral diarrhea virus (BVDV) cytopathic strains 87-2552 (field isolate) and NADL and Singer (prototype strains) was demonstrated with monoclonal antibodies (MAbs) in enzyme-linked immunosorbent, immunofluorescence, virus neutralization, and immunoprecipitation assays. Two MAbs against BVDV strain 87-2552, designated D11 and B7, strongly neutralized this field...
متن کاملBovine Viral Diarrhea Virus Control and Eradication
BVDV is estimated to cost an average dairy between $20 and $160 per adult cow per year. These losses include medication and labor to treat acute infections, milk production losses in lactating cows, infertility due to decreased conception and early embryonic death, abortions, loss of weak, abnormal, or persistently infected calves. Large scale herd outbreaks such as occurred in the early 1990s ...
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 کاملEffects of oocytes exposure to bovine diarrhea viruses BVDV-1, BVDV-2 and Hobi-like virus on in vitro-produced bovine embryo development and viral infection.
As production of in vitro (IVP) bovine embryos steadily increases, the sanitary risk associated with IVP embryos remains a concern. One of the greatest concerns is how BVDV may be transmitted through IVP embryos. The objective of this study was to evaluate the effects caused by BVDV-1, BVDV-2 and Hobi-like virus exposure during in vitro maturation on embryo development and viral infection. Abit...
