BVDV Management

American Association of Bovine Practitioners Conference Proceedings, 2007
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 ...

Experiences from BVDV control in Sweden

Preventive Veterinary Medicine, 2005
A 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

Detection of antibodies to bovine viral diarrhoea virus (BVDV) and characterization of genomes of BVDV from Brazil

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, 2002
Bovine 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 ...

Economic impact of BVDV infection in dairies

Biologicals, 2003
The 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

BVDV control and eradication in Europe--an update.

The Japanese journal of veterinary research, 2012
Infections with bovine viral diarrhoea virus (BVDV) are endemic in cattle populations worldwide and result in major economic losses. For long, attempts to control BVDV were limited to prophylactic vaccination practices, implemented primarily to reduce or prevent clinical disease on a herd basis.

The vaccination and challenge with bovine viral diarrhea virus (BVDV) of calves previously infected with a non-cytopathic BVDV

Comparative Immunology, Microbiology and Infectious Diseases, 1991
Four calves were infected with noncytopathic (NCP) New York-1 strain of bovine viral diarrhea virus (BVDV). During the observation period of one month the calves remained clinically normal but the virus was repeatedly recovered from their pharyngeal swabbings and blood.

A new inactivated BVDV genotype I and II vaccine An immunisation and challenge study with BVDV genotype I

Veterinary Microbiology, 2000
An inactivated vaccine containing BVDV I and II strains (PT810; BVDV I, and 890; BVDV II) and using different adjuvants and antigen dosages was tested in a cattle challenge model. Groups of six healthy, seronegative cattle were vaccinated twice with a low dose (10(6.6) TCID(50) PT810 and 10(7.2) TCID(50) 890) vaccine with the adjuvant Bay R1005 or a ...

Serological and virological BVDV prevalence and risk factor analysis for herds to be BVDV seropositive in Belgian cattle herds

Preventive Veterinary Medicine, 2013
Bovine viral diarrhoea virus (BVDV) is a worldwide spread virus that most commonly infects cattle and can cause considerable economic losses. To determine the prevalence of BVDV in Belgium, a cross-sectional study was performed between November 2009 and March 2010. Young stock aged between 6 and 12 months from 773 randomly selected Belgian cattle herds

The immune response of cattle, persistently infected with noncytopathic BVDV, after superinfection with antigenically semi-homologous cytopathic BVDV

Veterinary Immunology and Immunopathology, 1998
Cattle persistently infected (PI) with noncytopathic (ncp) bovine virus diarrhea virus (BVDV) are at risk for developing fatal mucosal disease (MD), which is considered to occur after superinfection with antigenically homologous cytopathic (cp) BVDV. In this study, we intranasally inoculated four PI-animals, that were PI with 2 ncp BVDV strains with 10(
