3.4 Phylogenetic analysis of P. aeruginosa AUST-03
isolates
A total of 28 P. aeruginosa ST242 genomes from human sources were
closely related to the strains from this study as displayed in Figure 2.
The P. aeruginosa ST242 strains from this study formed five
distinct clusters with the global P. aeruginosa ST242 strains at
a cut-off of 20 SNPs. The largest of these was Cluster 2 that consisted
of three strains from P2 and the single strain from P4 and also included
strains from Canada, China, Denmark and Slovenia. The remainingP. aeruginosa ST242 from P2 formed Cluster 3 which consisted of
three study strains and strains from Canada and Slovenia, while a single
P2 strain from Cluster 7 clustered with a strain from Canada. Clusters 8
and 11 consisted only of P2 study strain/s.
