Complete Genomic Sequence of a New Muscovy Duck-Origin Reovirus from China

The complete genomic sequence of a new Muscovy duck-origin reovirus (N-MDRV), strain J18 from China, was determined. The virus has a tricistronic S1 genome segment that is distinct from the originally described MDRV, which possesses a bicistronic S4 genome segment. Pairwise comparisons and phylogenetic analyses suggest that N-MDRV J18 is a new isolate within the species Avian orthoreovirus.
