Figure 2.

Split network obtained using the SNPs of the core genome to depict the impact of recombination on 44 S. pneumoniae strains. In this representation, all the conflicting phylogenetic signals due to each SNP are represented as alternative bipartitions that account for the non-tree-like structure of the inner part of the network. The six lineages highlighted in Figure 1 are also indicated.
