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 ...

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.

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

A survey for bvdv antibodies in cattle farms in Slovakia and genetic typing of bvdv isolates from imported animals

Acta Veterinaria Hungarica, 2003
A serological survey for bovine viral diarrhoea virus (BVDV) antibodies on a collection of 1295 serum samples obtained from 6-12 months old cattle originating from 45 farms in Slovakia was carried out. On 13 farms more than 90% of the examined animals were seropositive, on 14 farms 71-90% seroprevalence was observed, on 13 farms only 50-70% animals ...

Investigation of a dual fetal infection model with bovine viral diarrhoea viruses (BVDV)-1 and BVDV-2

Archives of Virology, 2011
Two studies were performed in pregnant heifers to determine whether inoculation with two bovine viral diarrhoea viruses (BVDV), one BVDV-1 and one BVDV-2, inoculated separately into either nostril, results in fetal infection with both viruses.

Trends in the BVDV Serological Response in the Upper Midwest

Biologicals, 2003
Bovine viral diarrhoea continues to be an important disease affecting both beef and dairy animals of all ages. One of the quickest means of measuring bovine viral diarrhoea virus (BVDV) exposure and infection in the herd is a serum neutralization (SN) assay. Type 1 and type 2 BVDV SN results from the Animal Disease Research and Diagnostic Laboratory at

Diagnostic assays applied in BVDV control in The Netherlands

Preventive Veterinary Medicine, 2005
In The Netherlands, a voluntary bovine virus diarrhoea virus (BVDV)-free certification programme was started in 1997. After an intake procedure in which all cattle are tested for the presence of BVD virus, a herd obtains the status "BVD-virus-free". To maintain this status a monitoring procedure is executed to verify absence of BVDV circulation in the ...

Bovine viral diarrhea virus (BVDV) 1b: predominant BVDV subtype in calves with respiratory disease.

Canadian journal of veterinary research = Revue canadienne de recherche veterinaire, 2002
The prevalence of bovine viral diarrhea virus (BVDV) infections was determined in 2 groups of stocker calves with acute respiratory disease. Both studies used calves assembled after purchase from auction markets by an order buyer and transported to feedyards, where they were held for approximately 30 d.

Prevalence of BVDV infection in Greek dairy herds

Preventive Veterinary Medicine, 2005
Thirty-nine Greek dairy herds, totalling 6333 cattle, enrolled in a voluntary bovine viral diarrhoea virus (BVDV) eradication programme based on the identification and removal of persistently infected (PI) animals. The aim of this study was to estimate the prevalences of BVD antigen-positive and PI animals, and investigate the significance of the ...

Beef Cowherd BVDV Management

American Association of Bovine Practitioners Conference Proceedings, 2003
Bovine viral diarrhea virus (BVDV) has a history of detrimentally affecting beef cattle production. Beef cattle veterinarians have an opportunity to utilize tools such as the veterinary decision making process to minimize the negative effects that BVDV has on profitability within individual cowherd.
