Phylogenetic tree of the concatenated amino acid sequence of PBP1a, PBP2b and PBP2x in Streptococcus pneumoniae with unique PBP-profiles. The tree was constructed using IQ-TREE software with a Blosum62 substitution model. Label contains isolate id, nearest PBP-profile (number of PBP amino acid substitutions), genotypic MIC, phenotypic MIC. Tree is colored by phenotypical susceptibility: Green is susceptible standard dosing regimen blue is susceptible increased exposure, red is resistant. The outlier sequence was constructed from Streptococcus dysgoloctiae AC2713. *indicates category disagreement.
