Pseudogel views of the mass range between 3 and 10 kDa of a susceptible (A,B) and a resistant (C,D) K. pneumoniae strain after incubation in the absence (lower panels) or presence (upper panels) of meropenem (64 μg/ml) for 1 h. For each incubation, four spectra acquired from two different spots are shown. Internal standard peaks are marked by arrows.
