Fig. 2: SNP network analysis of highly connected isolates.

Network diagram showing pairwise connections between isolates in our cohort with less than 15 pairwise SNP differences. The panels show the same network with the nodes colour-coded according to (A) lineages, (B) year of collection, (C) serotypes and (D) location of collection. The lines between pairs of isolates are colour-coded by the number of SNPs.
