Percentage of isolates of genotype amongst isolates with particular characteristic (percentages given only for those >10%).
Percentage of isolates with particular characteristic amongst total isolates (percentages given only for those >10%).
Altered expression means diminished expression of oprD of <40% or increased expression of mexA three times higher relative to the control strain P. aeruginosa PAO1.
