Phylogenetic analysis of invasive Streptococcus oralis expressing serotype 3 pneumococcal capsule from 2 adult patients, Japan. Asterisks and orange shading indicate genomes from isolates ASP0312-Sp and SP2752 identified in this study. Homologous core gene clusters of 71 strains from 3 Streptococcus oralis subsp., 2 S. pneumoniae, 5 S. mitis, 5 S. infantis, and 3 S. pseudopneumoniae were downloaded from the National Center for Biotechnology Information database (https://www.ncbi.nlm.nih.gov) and compared with the ASP0312-Sp and SP2752 genomes. Branch lengths represent the genetic distance. Scale bar indicates nucleotide substitutions per site.
