BACKGROUND BVD and IBR are contagious viral diseases highly prevalent in Irish cattle. Despite their significant reproductive and economic impact very little is known about the BVD and IBR status of stock bulls (a bull used for breeding purposes). There are still a high proportion of dairy farms in Ireland that rely on the use of a bull for breeding cattle and ensuring the fertility of the bull...

Following several clinical cases of suspected bovine virus diarrhoea (BVD) on three Namibian cattle farms, a serological survey was conducted on bovine, ovine, caprine and wild ruminant sera originating from different regions of the country. Neutralizing antibodies to BVD virus (BVDV) were detected in 58% of 1,014 cattle sera, 14% of 618 sheep sera and 4.6% of 1,118 goat sera. Sera from seven o...

BACKGROUND In 2008, a program to eradicate bovine virus diarrhea (BVD) in cattle in Switzerland was initiated. After targeted elimination of persistently infected animals that represent the main virus reservoir, the absence of BVD is surveilled serologically since 2012. In view of steadily decreasing pestivirus seroprevalence in the cattle population, the susceptibility for (re-) infection by b...

The expression of biotype-specific epitopes in cells infected with cytopathic (cp) and non-cytopathic (ncp) bovine viral diarrhoea virus (BVDV) was analysed by immunofluorescence. Four monoclonal antibodies (MAbs) directed against different epitopes on the viral glycoprotein gp48 were used. With cells infected with cpBVDV strain NADL, the four MAbs yielded a strong and granular cytoplasmic fluo...

BACKGROUND Calf output is a key element in determining the profitability of a suckler beef enterprise. Infectious agents such as Bovine Virus Diarrhoea (BVD) virus, colostrum management and parasitic challenge can all affect calf output. Prior to the national BVD eradication programme, there was little published information on either the prevalence or effect of BVD in Irish beef herds. There is...

Antigenic and genomic relationships between five pairs of non-cytopathic and cytopathic bovine viral diarrhoea (BVD) viruses isolated from cattle with mucosal disease were examined. Antigenic similarity was evaluated by studying the binding characteristics of 10 monoclonal antibodies (MAbs) directed against the gp53 BVD virus glycoprotein. The MAb binding match between members of the same virus...

Introduction Bovine Viral Diarrhea (BVD) virus and Infectious Bovine Rhinotracheitis (IBR) virus are two of the major viral pathogens responsible for respiratory disease in cattle. These viral agents can be associated with pathology in the respiratory, immunologic, neurologic, hematologic, lymphatic, and reproductive organ systems (Grooms et al., 1998). Infections of cattle with BVD virus and/o...

Two hundred and thirty-nine cattle from Gauteng Province in South Africa were tested for various pathogens causing reproductive diseases includingbovine viral diarrhoea/mucosal disease (BVD/MD) virus, infectious bovine rhinotracheitis/infectious pustular vulvovaginitis (IBR/IPV) virus, Neospora caninum and Brucella abortus usingvarious tests. For BVD/MD virus, 49.37% tested positive, 74.47% for...

As part of the preparatory phase of a disease control programme in three herds infected with bovine virus diarrhoea-mucosal disease (BVD-MD) virus (demonstrated by virus isolation), initial serological screening was performed on all livestock older than six months (351 animals) by blocking enzyme-linked immunosorbent assay (ELISA) using a monoclonal antibody recognising a common epitope to the ...
