Phylogenetic network analysis of translated nhba subvariants among N. lactamica and invasive meningococci collected in England, Wales, Northern Ireland, and Ireland. (a) Phylogenetic network of translated nhba subvariants from meningococci and N. lactamica, in which peptide subvariants identified among N. lactamica isolates are highlighted with red circles. (b) Overall distribution of meningococci and N. lactamica isolates among the most-populous clades. Blue and red circles highlight clades dominated by meningococci and N. lactamica, respectively. The text indicates the proportion of isolates and the number of clonal complexes represented by each highlighted clade. Red text refers to N. lactamica and black text refers to meningococci. NHBA peptide identifications (IDs) (in accordance with PubMLST.org) can be viewed in Fig. S1 in the supplemental material. UA, unassigned ST.
