VALIDITY OF ASCORBIC ACID AS VIRAL INACTIVANT FOR INFECTIOUS BOVINE RHINOTRACHEITIS VIRUS AND BOVINE VIRAL DIARRHEA VIRUS

Serological Surveillance of Infectious Bovine Rhinotracheitis virus, Bovine viral diarrhea virus and Bovine Parainfluenza-3 virus in Saudi Arabia

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...

Detection 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...

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...

Bovine 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 ...
