Fig. 2. — Genetic relatedness of outbreak, environmental and reference L. pneumophila strains. Phylogeny is based upon a neighbour-joining tree of the concatenated segments of core bacterial loci (trpS, ftsZ and trpS) and Legionella-specific virulence determinants (lidA, icmO, sidA, total 4243 nucleotides per entry). GenBank accession numbers for previously sequenced loci are presented in the text, and strains from the current study are abbreviated from the form 05-L-0XX to LXX. The source is indicated in parentheses. Bar, scale of the distance score.
