Escherichia coli viability and membrane damage following treatment with cathelicidins. Membrane damage in E. coli treated with each synthetic cathelicidin peptide (5 μM) was detected with a LIVE/DEAD BacLight Bacterial Viability Kit. Green fluorescence indicates live bacteria with intact membranes; red fluorescence indicates dead bacteria with damaged membranes. CATH1 cathelicidin1, CATH2 cathelicidin2, CATH3 cathelicidin3, and CATHB1 cathelicidinB1
