Figure 2. Phylogenetic reconstruction by using an unrooted neighbor-net algorithm of core genomes of clonal complex 11 Neisseria meningitidis strains with serogroup W capsules (MenW:cc11), Western Australia, Australia, January 2013–December 2016. Blue circles indicate isolates in cluster A from Western Australia; red circles indicate isolates in cluster B from Western Australia; gray circle indicates ExNm672, a strain isolated from a traveler; open squares indicate the 5 MenW:cc11 isolates in the PubMLST database (http://pubmlst.org/neisseria) that contains the penA_253 allele; and black squares indicate reference MenW:cc11 strains, isolated after 2010, as described by Lucidarme et al. (8). M7124 is the Hajj clone isolated in Saudi Arabia in 2000. Numbers in parentheses indicate PubMLST numbers of reference isolates. Scale bar indicates nucleotide substitutions per site.
