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 کاملPrevalence, outcome, and health consequences associated with persistent infection with bovine viral diarrhea virus in feedlot cattle.
OBJECTIVE To estimate prevalence of cattle persistently infected (PI) with bovine viral diarrhea virus (BVDV) at arrival at a feedlot, prevalence of chronically ill and dead PI cattle, and the magnitude of excess disease attributable to a PI animal. DESIGN Cross-sectional and cohort studies. ANIMALS 2,000 cattle at the time they arrived at a feedlot, 1,383 chronically ill cattle from 7 feed...
متن کاملComparative prevalence of Bovine Viral Diarrhea Virus antibodies among native and imported cattle in north of Sistan and Baluchistan- Iran
Background and Aims: Sistan is a major pole in dairy production and genetic resource for the unique sistanian breed in the southeast of Iran. This region has a wide border with Afghanistan and cattle imports are done through this border. The main aim of this study was to compare the seroprevalence of Bovine Viral Diarrhea Virus (BVDV) infection rate using direct Enzyme-linked ...
متن کاملBovine Viral Diarrhea (BVD)
Bovine viral diarrhea virus (BVDV) is an economically important pathogen of cattle and it occurs worldwide. The biology of this virus is complex because it is associated with many diverse clinical manifestations, ranging from mild acute infections to fatal mucosal disease. BVDV can infect cattle at all ages including the fetus (1-3). Serological evidence shows that BVDV is a common infectious a...
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...
