| Popis: | Introduction: Enteric viruses, including noroviruses and adenovirus are pathogens associated with outbreaks and sporadic cases of gastroenteritis in worldwide. This study aimed investigate cases of gastroenteritis caused by noroviruses and adenoviruses in children attending Public Daycare Centers in Brazil. Material and Methods: In this study, 135 fecal samples were examined using RT-PCR assays, sequencing and phylogenetic analysis. Results: The prevalence for norovirus and adenovirus was 13.3% (18/135) and 58.5% (79/135), respectively. Noroviruses were more frequent in symptomatic individuals (22.7%), whereas adenoviruses were more observed in asymptomatic children (61.8%). Three norovirus genotypes were detected (GII.P4, GII.P7, GII.P12) and adenovirus strains were classified into five species (A-F). The data revealed the dynamics of genotypic distribution of noroviruses and adenoviruses among children attending day care centers. The data indicated that symptomatic and asymptomatic children were infected with several strains of NoV e AdV. The additional evolutionary analyses need to be further investigated. |
