ABSTRACT
Rotaviruses are one the causes of enteritis and diarrhea in avian species, resulting in negative impact on egg and poultry production. The objective of this work was to detect and characterize Rotavirus F (RVF) and G (RVG) found in Brazilian commercial avian farms. A total of 97 intestinal contents was collected between 2008 and 2015 from 10 Brazilian states, and submitted to two different RT-PCR, targeting a fragment of viral VP6-coding nucleotide sequence of each viral group. Amplicons were further submitted to genetic sequencing and analyzed by phylogenetic analysis. There were 5 RVF positive samples (5.15%) in 2 broilers, 1 laying hen and 2 breeders. Only one RVG sample (1.03%) was detected in laying hen, in coinfection with RVF. This data contributes to a better understanding of rotavirus distribution in Brazil.
