Relative fitness of a minority mexT- (~5%, strain PT5) in a majority of mexT+ (strain PT149) after 48 hours of growth in casein medium as a function of different concentrations of Chloramphenicol. All samples (including the no antibiotic sample) has the same level of ethanol carrier. Relative fitness is defined as in Fig. 3 caption. Error bars represent the standard error of the mean of six biological repeats, three with the minority marked with BFP and three with the minority marked with GFP. See Fig. S4 for separate graphs of the two markers.
