Figure 2.

Comparison of normalized cefotaxime (red), ceftriaxone (yellow), and ceftazidime (blue) logRQ values for 17 OXA-48 producers (clinical isolates of Klebsiella pneumoniae and Escherichia coli) represented by dots. LogRQ values above the cut-off are considered positive (0.4, green line) and values below the cut-off (0.2, black line) are considered negative. Intermediate values (between the green and black lines) are ambiguous. The E. coli J53 control strain and the transconjugant of the latter carrying the ~62-Kb IncL plasmid with the bla_OXA-48 gene are represented by diamonds and triangles, respectively, using the same color code as in the experiment.
