Journal of Animal Science (88)13 Suppl 2010
Abstract
Members of the public are always somewhat aware of foodborne and other zoonotic pathogens; however, recent illnesses traced to produce and the emergence of pandemic H1N1 influenza virus have increased the scrutiny on all areas of food production. The Council for Agricultural Science and Technology h...

Journal of General Virology (91)Pt 3 2010
Abstract
The objective of this study was to determine the prevalence of anti-norovirus (NoV), -sapovirus (SaV) and -Tulane virus (TV) antibodies in rhesus macaques of the Tulane National Primate Research Center and to evaluate the antigenic relationship between these viruses. A high prevalence of NoV-binding...

Abstract
Despite its common occurrence, the aetiology of chronic gingivostomatitis in cats remains uncertain. Aetiology is likely multifactorial, and several infectious agents may be associated with chronic gingivostomatitis. The purpose of this study was to investigate the prevalence of feline calicivirus (...

Voprosy Virusologii (54)6 2009
Abstract
The review deals with calicivirus infection that has long been known in animals, but also just recently disclosed in humans. Human caliciviruses induce outbreaks of acute gastroenteritis in all countries of the world, which makes this immunobiological research very actual. The history of this discov...

Recovery of infectious virus by transfection of in vitro-generated RNA from tulane calicivirus cDNA.
Abstract
We demonstrated that RNA transcripts made in vitro from the full-length genomic cDNA of TV were infectious upon transfection into permissive LLC-MK2 cells. The recombinant virus exhibited plaque morphologies and growth kinetics similar to those of the wild-type virus in this cell line. Capping was r...

Abstract
We have developed a subclone of hepatocyte-derived HepG2 cells (clone N6) that maintains functional characteristics of polarized hepatocytes but displays morphology typical of columnar epithelial cells, rather than the complex morphology that is typical of hepatocytes. N6 cells form microcolonies of...

Abstract
Whether animals may act as reservoirs for human caliciviruses is unclear. By sequence analysis of a short fragment of the RNA-dependent RNA polymerase (RdRp) region, porcine sapovirus (SaV) strains that genetically resemble human SaVs have been detected in piglets, but more-informative sequences (ca...

An equal error rate (EER) of 2% is obtained for verification of Rotavirus (tested against three other viruses) when features from 15 viral particle images are averaged. It drops further to less than 0.2% when scores from two tests are averaged to make a decision. For verification of Astrovirus (test...

Abstract
We have shown a direct interaction of the calicivirus VPg with the cap-binding protein eIF 4 E. This interaction is required for calicivirus mRNA translation, as sequestration of eIF 4 E by 4 E-BP 1 inhibits translation. Functional analysis has shown that VPg does not interfere with the interaction...
