Important differences in MIC distribution in between E and L isolates (Wilcoxon matched-pairs signed-rank test) for CAZ (p: 0.03), MEM (p: 0.01), and CIP (p: 0.01).FIGURE 1 | MICs of three antibiotics within the 18 pairs of isolates collected successively in the very same patients with an interval time ranging from 1 to 11 years. The graphs show the person MIC for each and every isolate, together with the geometric imply rep-resented by the red horizontal line. Only antibiotics for which a important difference among the successive isolates (Early vs. late) was observed are illustrated (see Table 1).

All of the data are compiled in Supplementary Table 3 together with azithromycin MICs (berberine) and axyB or axyX gene expression levels. Within this Supplementary Table 3, we particularly determine in blue colour the mutations that distinguish A. xysoloxidans ATCC 27061 from A. insuavis AXX-A, and isolates are ordered to show close from one a different thosewhich share the exact same mutations, classified based on their MIC. Three silent mutations (T96C, T123C, and T411C) were usually observed in rpl4, including in a. xysoloxidans ATCC 27061, though a handful of other people have been only seen in clinical i.
