Memórias do Instituto Oswaldo Cruz, Rio de Janeiro, v. 104, n. 4, p. 655-658, 2009.0074-0276e- 1678-8060http://repositorio.bc.ufg.br/handle/ri/16727Out of 1,588 faecal samples of children taken from three locations of the Central West Region of Brazil, 57 were positive for astroviruses (HAstVs) using reverse transcription-polymerase chain reaction (RT-PCR). They were geno- typed by nested RT-PCR and/or genomic sequencing. HAstV-1 (42.8%), HAstV-2 (23.2%), HAstV-3 (3.6%), HAstV-4 (14.3%) and HAstVs -5, -6, -7 and -8 (1.8% each) were detected. In Goiânia and Campo Grande, HAstV-1 was the most frequently detected genotype while in Brasília (DF) it was HAstV-2. Shifts in the circulation of astrovirus geno-types were observed in DF and Campo Grande. All samples collected by rectal swabs were viral negative. The astro-virus genotypes were detected in all age groups and there was no correlation between genotype and age group.engAcesso AbertoBrazilAstrovirusGenotypingSequencingNested-PCRArtigo10.1590/S0074-02762009000400021
