Phylogenetic Analyses of the VP4 and VP7 Genes of Porcine Group A Rotaviruses in São Paulo State, Brazil: First Identification of G5P[23] in Piglets

Abstract

This study determined the group A rotavirus occurrence in pig farms from 7 different cities in São Paulo State, Brazil. Out of 143 samples, 70 tested positive. Sequence analyses of 37 strains indicated that the strains had the G3, G5, G9, and P[6], P[13]/P[22]-like, and P[23] genotypes.
