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 ...

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, 2003Bovine 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, 2005In 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 ...

First report of BVDV circulation in sheep in Argentina
Preventive Veterinary Medicine, 2009Pestiviruses 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

Bovine viral diarrhea virus (BVDV) 1b: predominant BVDV subtype in calves with respiratory disease.
Canadian journal of veterinary research = Revue canadienne de recherche veterinaire, 2002The 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, 2005Thirty-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 ...

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.

Veterinary Immunology and Immunopathology, 2013
The purpose of this study was to compare clinical and virological differences between non-cytopathic (ncp) bovine viral diarrhea virus (BVDV)-1 and ncp BVDV-2 isolated from Korean field cases. Each five naïve calves were experimentally infected with Korean ncp BVDV-1 or BVDV-2 isolates.

Persistent BVDV infection in mousedeer infects calves. Do we know the reservoirs for BVDV?
Preventive veterinary medicine, 2006Bovine 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.
