Molecular characterization of human astroviruses isolated in Brazil, including the complete sequences of astrovirus genotypes 4 and 5.

P A Silva1, D D P Cardoso, E Schreier.   

Abstract

Human astroviruses (HAstV) are recognized as an important cause of gastroenteritis in young children worldwide. This study describes the molecular characteristics of astroviruses isolated in Brazil, using RT-PCR and molecular sequencing of segments of all three viral ORFs. Genetic analysis of a 348-nucleotide segment from ORF 2 demonstrated that the Brazilian isolates belong to HAstV genotypes 1 to 5 and 8. ORF 1b sequences displayed a high degree of nucleotide identity even between different genotypes, which disfavours HAstV genotyping in this region. ORF 1a sequence analysis classified all Brazilian samples as genogroup A. The complete sequences of HAstV genotype 4 (putative serotype 4) and genotype 5 (putative serotype 5) were determined for the first time.
