Figure Lengend Snippet: Antibacterial effect of pinaverium bromide on the planktonic cells of S. aureus and E. faecalis . The S. aureus CHS101 isolate (A) and E. faecalis 16C106 isolate (B) during the logarithmic growth phase were treated with pinaverium bromide for 24 h. The planktonic cells were determined by cfu numbers. The data presented were the average of three independent experiments (mean ± SD). Pin, pinaverium bromide; Lin, linezolid; Van, vancomycin; and Amp, ampicillin. All antimicrobials were used at 4 × MIC.

Figure Lengend Snippet: Inhibitory effect of pinaverium bromide on the formation of S. aureus and E. faecalis persister cells. The S. aureus CHS101 isolate (A) and E. faecalis 16C106 isolate (B) during stationary growth phase were treated with pinaverium bromide for 120 h. The planktonic cells were determined by cfu numbers. The data presented were the average of three independent experiments (mean ± SD). Pin, pinaverium bromide; Lin, linezolid; Van, vancomycin; and Amp, ampicillin. All antimicrobials were used at 10 × MIC.

Figure Lengend Snippet: CAMPs induce ROS-independent DSBs in genomic DNA of E. coli ATCC 25922. (A) LMA-encapsulated cells were treated with CAMPs (100 μg/mL), levofloxacin (0.5 μg/mL), or ampicillin (50 μg/mL) (see Materials and Methods section) and DSB formation was monitored using PFGE. Lane 1 – levofloxacin; Lane 2 – ampicillin; Lane 3 – L1L; Lane 4 – L1D; Lane 5–24L; Lane 6–24D; Lane 7 – LCAPL2; Lane 8 – LCAPL8; Lane 9 – untreated cells; (B) LMA-encapsulated cells were treated with peptides 24L, L1D, and ST1 in the absence (lanes 2, 4, and 6) or presence (lanes 3, 5, and 7) of 100 mM TU. Lane 1 and Lane 8 show levofloxacin and untreated cells, respectively. For full images please see Supplemental Material.
