A: Phylogeny of S. pneumoniae isolates (serotype analysis). Isolate names are shown in brackets while the corresponding serotypes are indicated outside brackets; Non-pneumococcal isolates are shown by dotted lines. Invasive isolates are shown in red while carriage isolates are shown in green; + indicates p = 1.0 while × indicates p > 0.9. B: Phylogeny of S. pneumoniae isolates (sequence type analysis). Isolate names are shown in brackets while the corresponding MLST are indicated outside brackets; Non-pneumococcal isolates are shown by dotted lines. Invasive isolates are shown in red while carriage isolates are shown in green; STND indicates MLST of the isolate was not determined; + indicates p = 1.0 while × indicates p > 0.9.
