Genetic diversity amongst Pseudomonas aeruginosa genotypes collected from each ecological setting, all Queensland sources and the Pseudomonas aeruginosa PubMLST database.

1OTU, operational taxonomic unit containing groups of isolates that varied by a pairwise distance of 2Simpson’s and Shannon’s indices were calculated for OTUs, because only non-duplicate STs were included for analysis.3Comparison of each ecological source with the total dataset; P-values are presented in parentheses.4Comparison of non-duplicate STs between Queensland MLST dataset and global dataset (P. aeruginosa PubMLST database [27]).
