Rotaviruses (RVs) are the main cause of acute viral gastroenteritis in both humans and young animals of various species such as calves, horses, pigs, dogs, cats, and birds. The genetic diversity of RVs is related to a variety of evolutionary mechanisms, including point mutation, and genome reassortment. The objective of this study was to characterize(More)
This study reports on the surveillance for rotavirus genotypes and the identification of G12 human rotavirus in the Northern Region of Brazil. Rotavirus-positive samples were collected from children <5 years of age with acute diarrhea from January 2008 to October 2010. G2P[4] was the most prevalent genotype, accounting for 45.6% (126/303) of cases. Five(More)
On a world scale, group A human rotaviruses are the most common cause of severe acute gastroenteritis during infancy and childhood, including five (G1, G2, G3, G4, and G9) epidemiologically important genotypes. Among these, G2 denotes a different genogroup which appears to have a cyclic pattern of occurrence and yet little information is available about its(More)
