Journal ArticleDOI
Temperature inactivation of Feline calicivirus vaccine strain FCV F-9 in comparison with human noroviruses using an RNA exposure assay and reverse transcribed quantitative real-time polymerase chain reaction—A novel method for predicting virus infectivity
J. R. Topping,H Schnerr,J Haines,M Scott,M J Carter,M M Willcocks,K. Bellamy,David Brown,Jim Gray,Christopher Gallimore,A. I. Knight +10 more
TL;DR: The data suggest that norovirus possesses greater thermostability than this commonly used surrogate and indicate that current food processing regimes for pasteurisation are insufficient to achieve inactivation of GII.4 NoVs.
Journal ArticleDOI
Comparative study of the epidemiology of rotavirus in children from a community-based birth cohort and a hospital in South India.
Indrani Banerjee,Sasirekha Ramani,Beryl Primrose,Prabhakar D. Moses,Miren Iturriza-Gomara,Jim Gray,Shabbar Jaffar,Bindhu Monica,Jaya Prakash Muliyil,David W. Brown,Mary K. Estes,Gagandeep Kang +11 more
TL;DR: G10P[11] strains resembling a vaccine candidate strain caused disease in the community, indicating the need for careful epidemiological studies as well as safety studies for the vaccine candidates.
Journal ArticleDOI
Prevalence of antibodies to Norwalk virus in England: detection by enzyme-linked immunosorbent assay using baculovirus-expressed Norwalk virus capsid antigen.
TL;DR: The prevalence of Norwalk virus antibody differed regionally and was lowest in 6- to 11-month-old infants and increased to 89.7% in persons over 60 years old.
Journal ArticleDOI

TL;DR: Fecal samples from gastroenteritis cases positive for group A rotavirus antigen were collected from multiple European countries from 2005 to mid-2008 and were subjected to G and P genotyping, providing valuable background information on theRotavirus strain diversity in Europe before the introduction of rotav virus vaccines.
Journal ArticleDOI
Human caliciviruses in symptomatic and asymptomatic infections in children in Vellore, South India.
Bindhu Monica,Sasirekha Ramani,Indrani Banerjee,Beryl Primrose,Miren Iturriza-Gomara,Christopher Gallimore,David W. Brown,Fathima M,Prabhakar D. Moses,Jim Gray,Gagandeep Kang +10 more
TL;DR: This is the first report of genotyping of circulating caliciviruses in both hospital and community in India and has increased the evidence for the role of these viruses in pediatric gastroenteritis in India.
