The 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 کاملPersistent 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 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 first study of bovine immunodeficiency virus (BIV) and bovine viral diarrhea virus (BVDV) co- infection in industrial herds of cattle in two provinces of Iran
BIV is a well-known bovine immunosup-pressive cause, but its pathogenesis has not been well characterized. It seems that it is possible that cofactors such as co- infection with other bovine viral pathogens may play a role in enhancing the pathogenesis of BIV infection; BVDV also has immunosuppressive effects. OBJECTIVE: The aim of this study was determination of possible correlation between BI...
متن کاملEffect of Bovine Viral Diarrhea Virus on Macrophages Functions
Infection with bovine viral diarrhea virus (BVDV) is prevalent in the cattle population worldwide. An important aspect of BVDV infection is the immunosuppression which results from virus effects on the immune cells. Macrophages were recovered from normal caws, and were exposed to BVDV in vitro. Tests were carried out on the recovered macrophages to determine the effects of the virus on several ...
