Phylogenetic position of New Zealand group W clonal complex 11 (W:CC11) Neisseria meningitidis isolates within the global W:CC11 major lineages. Maximum-likelihood phylogeny was generated by RAxML version 8.2.12 (33) on the basis of the core single-nucleotide polymorphism alignment of 198 W:CC11 isolates. Branches with a bootstrap (200 replications) value >90% are indicated with a red dot. Excluding the basal older sublineages, all other isolates form 2 strongly supported clades marked as clade I and clade II, which correspond to the Hajj strain sublineage and the South America strain sublineage. All the major defined lineages of W:CC11 are marked and indicated by consistent background color of isolate’s identification number and branches. The inner ring and outer ring designate the region and year of isolation for each isolate. Scale bar indicates average number of substitutions per site.
