OBJECTIVE: verify rotavirus A genotype occurrence in children aged 1 to 36 months in Manaus-AM. METHODS: descriptive and retrospective study conducted from June/2004 to December/2006, through laboratory analysis of diarrheal stools of children aged 1 to 36 months cared for at a Child Emergency service in Manaus/Amazonas. RESULTS: 25% rotavirus A positivity was found using Polyacrylamide Gel Electrophoresis of Ribonucleic Acid. Reverse Transcriptase followed by Polymerase Chain Reaction were applied to positive samples and revealed 30.7% G genotypes and 44.7% P genotypes, with predominance of G2 (17%) and P[8] (66.7%) genotypes. 38.3% and 11.7% of the G and P genotype positive samples, respectively, showed no features of any of the G and P genotypes surveyed. CONCLUSION: 38.3% and 11.7% G and P genotypes, respectively, showed no characteristics of the genotypes studied, suggesting that genotypes different to these are in circulation.
