摘要：

We report on the complete characterization of S class gene segments of 12 newly isolated turkey arthritis reoviruses (TARVs) and compare it with that of a turkey enteric reovirus (TERV). Phylogenetic analysis of S2, S3 and S4 genome segments revealed grouping of all TARVs into two lineages while, on the basis of S1 genome segment, only one lineage was found. All TARVs had 95-100% nucleotide identity based on sigma C protein sequences (S1 segment) but varied from 90-100%, 88.9-100% and 88.7-100% on the basis of S2, S3, and S4 genome segments, respectively. Point mutations as well as possible reassortments were observed in TARVs throughout the S class indicating the need for extensive epidemiological studies on these viruses in hatcheries and commercial farms, which would be useful in determining virus variation in the field.
