Minimum inhibitory concentration (MIC) of moxifloxacin for P . aeruginosa clinical isolates with or without the exoU gene. The median for each group is represented by the line in the middle of each box. The interquartile range (IQR), the span of the 25th to 75th percentiles, is denoted by the lower and upper bounds of each box, respectively. The whiskers extend from the smallest MIC within 1.5 × IQR below the 25th percentile to the largest MIC within 1.5 × IQR above the 75th percentile. Individual data points denote values outside this range. Note that 3 additional isolates were identified and included compared to disk diffusion assay data; 2 were exoU(+) and 1 was exoU(−). The P-value displayed was obtained by two-group mean-comparison t-Test of the log, in base 2, of the MIC. The average MIC shown for each subgroup is the mean of the log, in base 2, of the MIC transformed to MIC in micrograms/ml.
