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 ...

First report of BVDV circulation in sheep in Argentina

Preventive Veterinary Medicine, 2009
Pestiviruses are capable of infecting a wide range of animals within the order Artyodactila. Currently, the genus Pestivirus includes Bovine Viral Diarrhea Virus 1 (BVDV-1) and 2 (BVDV-2), Border Disease Virus (BDV), and Classical Swine Fever Virus (CSFV). BVDV-1, BVDV-2 and BDV are able to cross species barrier to infect a wide range of hosts, whereas

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(

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.

Increased genetic diversity of BVDV strains circulating in Eastern Anatolia, Turkey: first detection of BVDV-3 in Turkey

Tropical Animal Health and Production, 2019
Bovine viral diarrhea virus (BVDV) is a pathogen associated with loss of meat, milk, and reproductive performance in cattle across the world. There have been two types of BVDV identified worldwide: BVDV-1 and BVDV-2. However, a new type of BVDV, named HoBi-like pestivirus (BVDV-3), has been identified recently. BVDV presence in Turkey has been reported

Persistent BVDV infection in mousedeer infects calves. Do we know the reservoirs for BVDV?

Preventive veterinary medicine, 2006
Bovine virus diarrhoea virus (BVDV)-1f was isolated from a Lesser Malayan Mousedeer in Copenhagen Zoo during a routine screening. Analysis of animals related to the Copenhagen mousedeer revealed that its mother and all siblings were virus positive, a pattern also seen for persistently infected (PI) cattle.

Challenges of BVDV eradication in ‘closed’ cattle herds

Veterinary Record, 2012
AT a recent meeting with a new dairy client I was informed that the herd was ‘closed’ as no cattle had been purchased for 20 years. However, this herd is typical of many – expanding cow numbers without expanding housing facilities on the main holding, requiring housing and grazing at premises away from home.
