Genomic analysis of rotavirus species a isolated from swine, Amazon region, Brazil

This present study has aimed to provide a molecular characterization of rotavirus species A (RVA) and to determine the frequency of RVC and RVH in fecal specimens from nonvaccinated piglets, across 5 farms in the metropolitan mesoregion of Belém, within the Amazon region, Brazil. In the previous study, porcine RVA was found in 9.9% (17/172) during the years 2008-2009. Using RT-PCR, Sanger nucleotide sequencing, and phylogenetic analyses, the entire genomes of 17 Brazilian porcine RVA strains were analyzed.
