Figure 2: Phylogenetic reconstruction using galE alleles from commensal and pathogenic Neisseria spp. using an un-rooted neighbour-net algorithum.

N. gonorrhoeae and commensal species are represented by circles with different colours denoting species. These were: N. meningitidis is black; N. lactamica is red: N. polysacchareae is pink; N. bergeri is mauve; N. cinerea is blue; N. elongata is orange; N. animalis and N. weaveri are grey; N. mucosa is white and N. subflava is green. N. meningitidis isolates are found in cluster A but also on branches in-between clusters A and B as well as the cnl in cluster B. N. gonorrhoeae are only found in one branch of cluster B and are labelled as N. gonorrhoeae without a symbol.
