Figure 3: Antimicrobial susceptibility testing of E. coli isolates 247. Flow cytometric test (A), agar diffusion test (B) and result of the automated system Walk- Away-96® (C). The red line shows the untreated control, the grey filled histograms bacteria incubated with different antibiotics. The part of fluorescent depolarized bacteria in the suspension is shown in percent. In accordance with the reference methods, this strain was resistant to mezlocillin, piperacillin and sensitive towards cefazolin, cefuroxime, ciprofloxacin and gentamicin.
