Fractions of regrowing cells after 4 h enrofloxacin exposure and a switch to LB (4 h/LB; 250 and 444 cells; same data as in d ) or under in vivo-mimicking conditions (IVM) with declining enrofloxacin concentrations and regrowth in nutrient-poor medium (276, 271 and 378 cells). Circles represent independent experiments. Two-tailed t -test on log-transformed data.
