Fig. 2From: Despite low viral titer in saliva samples, Sanger-based SARS-CoV-2 spike gene sequencing is highly applicable for the variant identificationPhylogenetic tree of SARS-CoV-2 strains retrieved from GISAID, including 147 strains registered by our study through REBIND. This phylogenetic tree contains 5533 SARS-CoV-2 strains retrieved from GISAID, all of which were submitted from Hiroshima, Japan, including 147 samples from this study that are shown with brown spots stating the sample ID and collection date. The light blue color represents the SARS-CoV-2 wild type, the red for the Alpha variant, the dark blue for the Delta variant, and the green for the Omicron variantBack to article page
