Figure 2

Phylogenetic trees based on the coding sequence of the SFTSV segments from a human patient in Japan and a Haemaphysalis aborensis tick collected from the patient. A) Large segment; B) medium segment; C) small segment. Blue circles indicate patient-derived SFTSV strains and red squares tick-derived strains from this study. Labels at right of each tree represent SFTSV genotypes A‒F. We derived the phylogenetic trees using the maximum-likelihood method and general time-reversible model and ran 1,000 bootstrap replicates using MEGA 11.0.13 (https://www.megasoftware.net). Scale bars indicate the number of base differences per site. SFTSV, severe fever with thrombocytopenia syndrome virus.
