Eradication of BVDV in cattle: the Norwegian project
Veterinary Record, 2013The intention of this collaborative project was eradication of pestivirus from the Norwegian cattle population of about 30,000 dairy and beef herds, primarily by identification and culling of persistently infected (PI) animals. Testing was performed in four tiers, with examination for pestivirus antibodies by indirect ELISA in (1) bulk milk, (2) pooled

Providing acquired immune protection against infection with bovine viral diarrhea viruses (BVDV) is challenging due to the heterogeneity that exists among BVDV strains and the ability of the virus to infect the fetus and establish persistent infections. Both modified live and killed vaccines have been shown to be efficacious under controlled conditions.

Acridine derivatives as anti-BVDV agents
Antiviral Research, 2011Twenty-six 9-aminoacridine derivatives were evaluated in cell-based assays for cytotoxicity and antiviral activity against a panel of 10 RNA and DNA viruses. While seven compounds (9, 10, 14, 19, 21, 22, 24) did not affect any virus and two (6, 11) were moderately active against CVB-5 or Reo-1, 17 compounds exhibited a marked specific activity against ...

Much progress had been made in defining BVDV in molecular terms. While this information has been useful in some aspects of BVDV pathogenesis, this information has not led to a significant decrease in concern expressed by practitioners regarding prevention and control of BVDV-induced disease.

Experiences from BVDV control in Sweden
Preventive Veterinary Medicine, 2005A control scheme on BVDV was launched in Sweden in 1993 with the aim to prevent spread of the infection between herds, to eliminate virus from infected herds and, ultimately, to eradicate BVDV from Sweden. At the start it was voluntary and fully financed by the affiliated farmers. The estimated prevalence of infected herds was 40%. After 11 years there

Bovine viral diarrhea virus (BVDV) control programs should include identification and removal of the BVDV persistently infected (PI) animal, biosecurity, biocontainment and surveillance. Surveillance of BVDV in herds previously identified as having persistently infected animals and for herds of unknown BVDV status are the focus of this discussion ...

Veterinary Microbiology, 1998
An ELISA for the detection of antibodies to bovine viral diarrhea virus (BVDV) was developed based on antigens derived from a genotype I BVDV strain isolated in Switzerland. Using monoclonal antibodies we showed that this antigen contained the conserved non-structural protein NS3 whereas it essentially lacked the more strain-specific E2 surface ...

Bovine viral diarrhea virus (BVDV) and anti-BVDV antibodies in pooled samples of follicular fluid
Theriogenology, 2002Bovine viral diarrhea virus (BVDV) can be found in cells and fluids from ovaries collected at the abattoir. On the other hand, immunoglobulins are also found in the fluid of ovarian follicles. Anti-BVDV antibodies in follicular fluid might reduce cross-contamination of COCs at the time of collection or hinder the use of virus isolation to test for the ...

Novel genomic targets for proper subtyping of bovine viral diarrhea virus 1 (BVDV-1) and BVDV-2
Virus Genes, 2023Whole-genome phylogenetic analysis, the most suitable strategy for subtyping bovine viral diarrhea virus 1 (BVDV-1) and BVDV-2, is not feasible for many laboratories. Consequently, BVDV isolates/strains have been frequently subtyped based on analysis of single genomic regions, mainly the 5' untranslated region (UTR). This approach, however, may lead to

Economic impact of BVDV infection in dairies
Biologicals, 2003The detrimental effects of bovine virus diarrhoea virus (BVDV) infections include reduced milk production, reduced reproductive performance, growth retardation, increased occurrence of other diseases, unthriftiness, early culling and increased mortality among young stock. These losses have been documented in several case descriptions and to some extent
