Pestivirus infection in pigs are responsible for raising sanitary barriers between countries. Infection caused by Bovine Viral Diarrhea Virus (BVDV) in pigs have been reported in countries such as China and the Netherlands, which brings concern about the existence of accurate diagnosis tests, questions about the risk factors involved, and the clinical form that BVDV infection may entail. Despit...

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...

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 ...

The preparation and preliminary testing of a subunit ISCOM (immunostimulating complex) vaccine against bovine virus diarrhoea virus (BVDV) is described. Vaccination of calves with this vaccine yields high neutralising titres against a panel of Danish BVDV field isolates. The serological difference between virus isolates and vaccine strain selection is discussed.

Here, we report two strains of Bovine viral diarrhea virus (BVDV), named XZ01 and XZ02, that were isolated from cattle in Tibet, China. They belong to subgenotype 1b. This report will help in understanding the molecular characteristics of BVDV in Tibetan cattle.

Characterisation of a new infectious full-length cDNA clone of BVDV genotype 2 and generation of virus mutants Novel BVDV-2 mutants as new candidates for modified live vaccines New insights into processing of bovine viral diarrhea virus glycoproteins Erns and E1

The variability of the 5' untranslated genomic region (5'UTR) of bovine viral diarrhoea virus (BVDV) RNA obtained from a single individual was analysed. Lung, kidney and spleen tissues from a naturally infected foetus were used as the source of viral RNA. A fragment of 288 bases of the internal ribosome entry site from the BVDV 5'UTR was amplified by RT-PCR using a proofreading DNA polymerase. ...

Two techniques performed on skin biopsy samples (ear notches), immunohistochemistry (IHC) and antigen-capture ELISA (AgELISA), were compared for detection of bovine viral diarrhea virus (BVDV) persistent infection (PI) in 559 Angus calves between the ages of 1 and 5 months. The calves also were tested for BVDV infection using virus isolation (VI) and reverse transcription (RT)-PCR on buffy coat...

In 1993, noncytopathic bovine viral diarrhea virus (BVDV) strains with enhanced virulence caused unprecedented outbreaks of severe acute bovine viral diarrhea (BVD) in dairy, beef, and veal herds in Ontario (Canada). Fever, pneumonia, diarrhea, and sudden death occurred in all age groups of cattle. Abortions often occurred in pregnant animals. Gross lesions in the alimentary tract were similar ...
