Comparison of polyaniline conductance signals by BYG Carba v1.0 and BYG Carba v2.0 assays. Intensity of the signal is expressed in arbitrary units and reflects the conductance of the sensor (Y axis). Main resistance mechanisms are indicated on the X axis. No carba/Carba vertical dotted line represents the boundary between the non-carbapenemase producers and the carbapenemase producers. Horizontal dotted line is the cut-off of positivity of the test (11.5 AU); Vertical bars on the curves represent standard deviation of 3 independent measures. The mean value for all positive values is 44.0 (CI95: 40.0–48.0) and 97.8 (CI95: 88.0–107.7) for BYG Carba v1.0 and BYG Carba v2.0 respectively and are significantly different (p < 0.00001 by independent two-sample Student’s t-test).
