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

Limited BVDV transmission and full protection against CSFV transmission in pigs experimentally infected with BVDV type 1b

Veterinary Microbiology, 2006
Bovine viral diarrhea virus (BVDV) in pigs may interfere with the detection and epidemiology of classical swine fever virus (CSFV). To investigate the importance of BVDV infections in pigs, first we studied the transmission dynamics of a recent BVDV field isolate.

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 ...

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(

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.

[Mental notes in tracking BVDV carriers].

Tijdschrift voor diergeneeskunde, 2006
The detection and elimination of animals persistently infected with bovine viral diarrhoea virus (BVDV) is the key to BVD control. This method has proven to be very efficient in eradicating BVDV in a herd. Several pitfalls in the detection procedure can make that some persistently infected (PI) animals do not get identified or are removed too late ...
