Cell wall permeability of E. coli after antibiotic treatment investigated by FACS. Flow cytometry measurements a + b of E. coli cultures stained with Syto 9 and propidium iodide (PI) after incubation with different antibiotics. a Forward scatter (FSC) vs Side scatter (SSC) dot plot of population of E. coli cells at 30 min time point. b Ratio of E. coli populations stained with propidium iodide and SYTO 9 alone post 5, 15, 30 and 45 min antibiotic treatment
