Figure Lengend Snippet: (A) A typical PAE experiment for E. coli ATCC 25922 after exposure to ceftriaxone or ciprofloxacin (each at a concentration equivalent to twice the MIC), as determined by viability counting. As shown, no PAE was seen after ceftriaxone exposure, but ciprofloxacin induced a PAE of 1.9 h. The organisms were stained with propidium iodide and examined by fluorescence microscopy. (B through D) Photomicrographs of untreated control organisms (B), ceftriaxone-exposed organisms 35 min after drug removal (C), and ciprofloxacin-exposed organisms 270 min after drug removal (D). Both antibiotics induced filamentation, but this morphological form persisted past the classically defined PAE in organisms exposed to ciprofloxacin. Magnification, ×880.

doi: 10.1039/c8cc08134d

Figure Lengend Snippet: F127-DG2 increases the OM permeability of P. aeruginosa. (A) Targeted F127-DG2/TPE micelles exhibit greater binding to the OM of P. aeruginosa than untargeted F127/TPE micelles based on increased TPE fluorescence (blue). F127-DG2/TPE does not target E. coli due to lack of the necessary OM receptors. Positive control staining performed with FM 4-64FX (red). (B) OM permeabilization with F127-DG2 (64 µM) results in greater HI accumulation (red) in P. aeruginosa than unmodified F127 (64 µM) + DG (128 µM), while E. coli OM permeability is unchanged. Positive control staining performed with SYTO13 (green). (C) NCF hydrolysis occurs more rapidly in P. aeruginosa treated with F127-DG2 (128 µM) than unmodified F127 (128 µM) + DG (256 µM); E. coli OM permeability is unaffected by either polymer.
