  • a Whole virus genomes were sequenced. Shown is the number of nucleotide changes in a total of 7,749 nucleotide sequences in viruses from the supernatants of T-705-treated MDCK cells compared to those in mock-treated MDCK cells. −, no nucleotide changes detected; *, P < 0.05 compared to mock-treated samples (unpaired two-tailed t test).
