Top. Feline calicivirus. [1] Thirteen species are placed in this family, divided among eleven genera. Analysis of biological characteristics was conducted, including growth rates, the number of infectious particles, cytopathogenic effects, and proteins expressed. Feline calicivirus (FCV) is frequently used as a surrogate of human norovirus. Nothing Reported Cite This Article. The human caliciviruses, like other members of the family Caliciviridae, are small (approximately 27 nm), nonenveloped RNA viruses with a single major capsid protein. And it is the same coronavirus that infects people. [2][3] Caliciviruses naturally infect vertebrates, and have been found in a number of organisms such as humans, cattle, pigs, cats, chickens, reptiles, dolphins and amphibians. Publications, Progress 10/01/16 to 09/30/17OutputsTarget Audience: Nothing Reported The Caliciviridae are a family of viruses, members of Class IV of the Baltimore scheme. The bacterial species Chlamydia felis and Mycoplasma felis also cause respiratory disease, and may complicate FCV infections. The generation of plaque mutants will continue to maintain stable populations, and to 'drive' continual mutation to further develop the mutant bank for looking at the evolution of pathogenesis and virulence of FCV. In animals, the genus Vesivirus most consistently causes vesicular blisters (vesicles) and ulcerations. Nothing Reported Objective 1: The goal of this research was to better understand the role of evolution, through genomic mutation, involved in the pathogenesis and virulence of RNA viruses. Transmission routes are fecal-oral.[3]. Entry into the host cell is achieved by attachment to host receptors, which mediate endocytosis. PLoS One 8(3):e59817. [4], Caliciviruses are not very well studied because until recently, they could not be grown in culture, and no suitable animal model has been found. Consistent plaque variants of large (FCV-Lg; greater than 5 mm in diameter) and small (FCV-Sm; less than 2 mm in diameter) have been produced and analysis was done. These symptoms emerge after an incubation time of 2 days and the symptoms only generally last for 3 days. Feline calicivirus (FCV) is a highly contagious virus in cats, and one of the main causes of respiratory infection. Norovirus spreads by contact with an infected person, particularly in crowded places, and also by the intake of infected food. CATS may be able to spread coronavirus to humans despite showing no symptoms, experts have warned. Second, the PI is on sabbatical all of 2015. Sapovirus, Norovirus, and Vesivirus have been detected in pigs, making this animal species of particular interest in the study of calicivirus pathogenesis and host range. FCV-genomic and mRNA samples were collected for sequence analysis. Cheetahs are the other species of the family Felidae known to become infected naturally. Nothing Reported It’s very common in cats and kittens and is usually caused by either the feline herpes virus (FHV) or feline calicivirus (FCV). Dictionary ! The PI is on sabbatical leave during 2015, but upon his return in January of 2016 will begin analysis of the plaque variants' replication characteristics and gene expression. DOI: 10.3201/eid1512.e11512. How have the results been disseminated to communities of interest?
