Bovine Leukosis Virus and Antibodies against Bovine Herpesvirus Type-1 and Bovine Viral Diarrhea Virus and in Buffaloes of the State of Pará, Brazil

Spatial analysis for bovine viral diarrhea virus and bovine herpesvirus type 1 infections in the state of Paraíba, northeastern Brazil

BACKGROUND Bovine Viral Diarrhea Virus (BVDV) and Bovine Herpesvirus type 1 (BoHV-1) cause reproductive problems in cattle and restrictions on international trade in animals worldwide. Both infections were detected in cattle herds in the Paraíba state, Northeastern Brazil, however, the spatial distribution and geographic identification of positive herds for these viruses has never been examined...

Prevalence of bovine herpesvirus-1, parainfluenza-3, bovine rotavirus, bovine viral diarrhea, bovine adenovirus-7, bovine leukemia virus and bluetongue virus antibodies in cattle in Mexico.

Comparative 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 ...

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...
