Description of rotavirus F in broilers from Brazilian poultry farms.

Rotaviruses are segmented double-stranded RNA viruses that cause gastroenteritis in mammals and birds. Here we describe the first partial nucleotide sequences of the structural protein VP6 from the genomes of group F rotaviruses that were detected in 5 out of 53 fecal samples (9.43%) from healthy broilers from Brazilian poultry farms based on reverse-transcriptase-PCR with primers designed for this study. The findings support the development of molecular detection systems, which can be used for the assessment of the distribution of rotavirus F in birds, their potential involvement in diseases, and their impact on poultry health.
