Strain descriptions and MICs^a

Strain	Source	MIC (μg/ml)
P. aeruginosa PA01	Laboratory strain	64
P. aeruginosa UR5586-10	UTI	16
P. aeruginosa BK6695-10	Blood culture	32
P. aeruginosa VA9057-10	Wound infection	32
Klebsiella pneumoniae DSMZ 30104	Laboratory strain	4
Escherichia coli ATCC 25922	Laboratory strain	2
Proteus mirabilis DSMZ 4479	Laboratory strain	8

^aStrain descriptions and MICs determined according to CLSI recommendations (4). MICs for Enterobacteriaceae strains are shown for comparison. The relatively high MICs of P. aeruginosa make it an ideal candidate to discriminate specific effects on biofilm from simple growth inhibition.
