Effect of piperacillin on growth and length of E. coli obtained by the oCelloScope system. a Quantification of bacterial growth kinetics and filamentation was determined for untreated (stippled lines) and cefotaxime-treated (solid lines) E. coli by two different algorithms: Growth kinetics (blue graphs) was measured based on segmentation and extraction of surface area, and bacterial length (green graphs) based on segmentation extracted average length. Images of E. coli morphology treated with 8 mg/L of cefotaxime were obtained by the oCelloScope system at time b 60 min, c 120 min, d 180 min, and at e 240 min
