A tree constructed from concatenated MLST data resolves species clusters in Neisseria. The 50% majority rule consensus tree shown was produced in Mr Bayes using third position sites within the concatenated sequences of Neisserial species as described in methods. Assigned species names are indicated by the symbols. Two subtrees, A and B, are shown. These both contain strains identified as N. mucosa, N. sicca and N. subflava, showing that these named species do not form single clusters by this method. In these subtrees, the clades containing exclusively N. lactamica or N. gonorrhoeae have been collapsed.
