Fig. 4. — Genetic relationships among Scotland throat and invasive isolates. Reconstructed phylogeny of the 122 Scotland strains inferred by neighbour-joining based on 1410 core SNPs is shown. The tree is rooted on clade 2 reference strain MGAS23530. Strains are coloured by infection, as indicated in the index. Throat and invasive isolates are intermingled throughout the tree, as groups they are not separate and genetically distinct.
