A novel human rotavirus serotype with dual G5-G11 specificity.

open access: yesJournal of General Virology, 1997
Rotavirus serotype G5 isolates were recently recovered from children with diarrhoea in Brazil. Like most human strains, they exhibited long electropherotypes and subgroup II and Wa-like VP4 specificity. We report the successful propagation and the molecular and antigenic characterization of one of these isolates (IAL-28). Cross-neutralization of IAL-28
