Overview of the Auckland GAS population. (a) Counts of isolates by emm-type, coloured by site of isolation and faceted by emm pattern type (A–C, D, and E). (b) Networks of minimum weight spanning trees of sequence clusters in the population. Clusters were defined by popPUNK where relative core and accessory distances for each pair were determined based on k-mer comparisons and split-kmer analysis. Nodes are scaled by the number of isolates within a 25 SNP threshold such that larger nodes containing multiple isolates are shown by larger circles with wedges representing multiple isolates within the node. Singleton clusters were excluded, and clusters are coloured by emm type and MLSTs are labelled.
