Figure 1. Phylogenetic analysis of flaA, pilE, asd, mip, mompS, proA, and neuA concatenated sequences from the 62 Legionella pneumophila serogroup 1 sequence types (STs) identified in Ontario. The tree was constructed with ClustalW2 (www.ebi.ac.uk/Tools/clustalw2/index.html) and the neighbor-joining method with 1,000 bootstrap replicates. Scale bar indicates genetic distances between sequences. STs in boldface were detected in outbreaks.
