Growth kinetics of attenuated Y. pestis strains. A1122 (GEN-S, DOX-S, CIP-S) and DSJB001 (GEN-R, DOX-R, CIP-NS) were evaluated over 18 h at 35 °C in the presence and absence of GEN (a), DOX (b) and CIP (c). Growth was measured by the Segmentation and Extraction of Surface Area (SESA) algorithm. Graphs represent the mean growth value ± standard deviations from three replicate wells
