VP2 is the outermost Bluetongue virus (BTV) antigenic protein, forming triskelion motifs on the virion surface. Although VP2 has been expressed successfully through many systems, its paracrine expression as a soluble form by mammalian cells represents a difficult task In the…

Recently, a new member of the Bluetongue virus (BTV) serogroup named Toggenburg Orbivirus (TOV) in goats from Switzerland has been described. The epidemiology and host range of TOV are currently unknown. Since TOV causes cross-reactions in laboratory tests used for BTV…

To determine the longevity of protective immunity following a single administration of emergency vaccine, and establish whether the immune response could be enhanced by increasing the antigen payload even further, cattle were vaccinated with an A22 Iraq vaccine containing…

Porcine circovirus type 2 (PCV2) is the essential etiological agent of postweaning multisystemic wasting syndrome (PMWS), a worldwide distributed pig disease. The involvement of the immune system in the pathogenesis of PMWS is considered crucial. Previous studies have shown…

Three-dimensional (3D) porcine nasal mucosal and tracheal mucosal epithelial cell cultures were developed to analyze foot-and-mouth disease virus (FMDV) interactions with mucosal epithelial cells. The cells in these cultures differentiated and polarized until they closely…

Enterohaemorrhagic Escherichia coli (EHEC) comprise a group of animal and zoonotic pathogens of worldwide importance. Our previous research established that intestinal colonization of calves by EHEC serotypes O5?:?H– and O111?:?H– requires EHEC factor for adherence (Efa-1)…

Sortase (a transamidase) has been shown to be responsible for the covalent attachment of proteins to the bacterial cell wall. Anchoring is effected on secreted proteins containing a specific cell wall motif toward their C-terminus; that for sortase A (SrtA) in Gram-positive…

The early identification of classical swine fever epizootics is hampered by difficulties in recognising early signs of infection, due to a lack of specific clinical signs. In addition many textbook descriptions of CSF are based on observations of disease caused by historic…

A lateral flow device (LFD) for the detection of foot-and-mouth disease virus (FMDV) of the SAT2 serotype was developed using a monoclonal antibody (Mab 2H6). The performance of the LFD was evaluated in the laboratory on suspensions of vesicular epithelia: 305 positive for…

A lateral flow device (LFD) for the detection of swine vesicular disease (SVD) virus (SVDV) and differential diagnosis from foot-and-mouth disease (FMD) was developed using a monoclonal antibody (Mab C70). The performance of the LFD was evaluated in the laboratory on…
