Acid dependent infection of Hela and Vero cells by BTV-10 occurs from within early-endosomes following virus uptake by clathrin-mediated endocytosis (Forzan et al., 2007: J Virol 81: 4819-4827). Here we report that BTV-1 infection of BHK cells is also dependent on a low…

The American grass carp reovirus (AGCRV) Aquareovirus G is not strongly associated with disease in fish, but it is often detected by cell culture during routine inspections of healthy fish. The cytopathic effect of AGCRV does not involve the typical syncytia associated with…

The production of prion particles in vitro by amplification with or without exogenous seed typically results in infectivity titers less than those associated with PrPSc isolated ex vivo and highlights the potential role of co-factors that can catalyze disease-specific prion…

Existing live attenuated classical swine fever virus (CSFV) vaccines provide a rapid onset of complete protection but pose problems in discriminating infected amongst vaccinated animals. With a view to providing additional information on the cellular mechanisms that may…

The nucleocapsid (N) protein of dolphin morbillivirus (DMV) was expressed from a baculovirus (Autographa californica nuclear polyhedrosis virus) vector and shown by SDS-PAGE and Western blot analysis to be about 57 kDa. Transmission electron microscopy revealed fully…

Equine rhinitis A virus (ERAV) is genetically closely related to foot-and-mouth disease virus (FMDV), and both are now classified within the genus Aphthovirus of the family Picornaviridae. For disease security reasons, FMDV can be handled only in high-containment facilities…

Following the arrival of bluetongue virus serotype 8 (BTV-8) in southeast England in September 2007, the Scottish Government commissioned research to assess the economic consequences of a BTV-8 incursion to Scotland. Here we present the first component of the assessment…

To deal with the incompleteness of observations and disentangle the complexities of transmission much use has been made of mathematical modelling when investigating the epidemiology of sheep transmissible spongiform encephalopathies (TSE) and, in particular, scrapie…

Major histocompatibility complex (MHC) class I chain-related (MIC) genes encode molecules that are expressed in response to stress, signalling immune system cells primarily via the activating receptor NKG2D. We investigated the expression of receptors for MIC in lymphocyte…

Foot-and-mouth disease virus (FMDV) causes a highly contagious infection in cloven-hoofed animals. Current inactivated FMDV vaccines generate short-term, serotype-specific protection, mainly through neutralizing antibody. An improved understanding of the mechanisms of…
