RESUMO
Human astrovirus (HAstV) 1-8 and highly divergent HAstVMLB1-3 genotypes have been detected in children both with and without acute gastroenteritis (AGE). One hundred and seventy fecal samples from children (≤5 years old) living in the Amazon region were evaluated for the presence of HAstV1-8, HAstV MLB1-3 and HAstVVA1-3, using an usual RT-PCR protocol and a new protocol with specific primers designed to detect HAstVMLB1-3. HAstVMLB1 and HAstV MLB2, as well as the HAstV3 and 5 genotypes were detected. HAstVMLB1-2 genotype was detected for the first time in Brazil at a frequency of 3.5% (6/170).
