Bactericidal effects of SMAP-29, KZ144, Art-085, and Art-175 against P. aeruginosa PAO1. A cell suspension was treated with equimolar amounts of SMAP-29, KZ144, Art-085, and Art-175 (3 μM) in the absence and presence of 0.125 or 0.5 mM EDTA. Bacterial reduction after 1 h is expressed in log10 units relative to the untreated control. Mean values (± standard deviation [SD]) are shown. An asterisk indicates when the detection limit (5.15 log units) was reached.
