Marker vaccine potential of a foot-and-mouth disease virus with a partial VP1 G-H loop deletion

Previous work in cattle and pigs demonstrated that protection against foot-and-mouth disease (FMD) could be achieved following vaccination with chimeric foot-and-mouth disease virus (FMDV) vaccines, in which the VP1 G-H loop had been substituted with that from another…

Crystal structure of equine rhinitis A virus in complex with its sialic acid receptor

Equine rhinitis A virus (ERAV) shares many features with foot-and-mouth disease virus (FMDV) and both are classified within the genus Aphthovirus of the family Picornaviridae. ERAV is used as a surrogate for FMDV research as it does not require high-level biosecurity. In…

Female-specific flightless phenotype for mosquito control

Dengue and dengue hemorrhagic fever are increasing public health problems with an estimated 50-100 million new infections each year. Aedes aegypti is the major vector of dengue viruses in its range and control of this mosquito would reduce significantly human morbidity and…

Murine norovirus-1 cell entry is mediated through a non-clathrin, non-caveolae, dynamin and cholesterol dependent pathway

For many viruses, endocytosis and exposure to the low pH within acidic endosomes is essential for infection. It has previously been reported that feline calicivirus uses clathrin-mediated endocytosis for entry into mammalian cells. Here, we report that infection of RAW264 7…

Airborne spread of foot-and-mouth disease model intercomparison

Foot-and-mouth disease virus (FMDV) spreads by direct contact between animals, by animal products (milk, meat and semen), by mechanical transfer on people or fomites and by the airborne route, with the relative importance of each mechanism depending on the particular…

A clathrin independent macropinocytosis-like entry mechanism used by bluetongue virus-1 during infection of BHK cells

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…

Detection and prevalence of the nonsyncytial American grass carp Reovirus Aquareovirus G by quantitative reverse transcriptase polymerase chain reaction

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…

Low density subcellular fractions enhance disease-specific prion protein misfolding

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…

Characterisation of virus-specific peripheral blood cell cytokine responses following vaccination or infection with classical swine fever viruses

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…

Expression from baculovirus and serological reactivity of the nucleocapsid protein of dolphin morbillivirus

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…
