The MIC distribution for Imipenem of Pseudomonas aeruginosa clinical isolates from the respiratory apparatus samples (n = 63) (a). Accumulated percentage of MIC, MBC, MICAD, and MBCAD for IPM in the sensitive isolates (n = 37) (b). MIC (circles on the solid line), MBC (circles on the dotted line), MICAD (triangles on the solid line), and MBCAD (triangles on the dotted line). The ratio distribution of planktonic bacteria (MBC/MIC) and adherent bacteria (MBCAD/MICAD) in IPM-sensitive isolates (n = 37) are shown (c). The white bars represent the number of strains of MBC/MIC in planktonic bacteria, and the black bars represent the number of strains of MBCAD/MICAD in the adherent bacteria.
