    Heat map represents antibiotic resistance of A. baumannii <t>DR1,</t> DR2, and AB067 strains. Antibiotic susceptibility testing was performed with different antibiotics in presence and absence of efflux pump inhibitor, (A) carbonyl cyanide m-chlorophenyl hydrazone (CCCP), and (B) reserpine against A. baumannii DR1, DR2, and AB067 strains. Data were tabulated and analyzed, and a heat map was constructed in GraphPad Prism software using mean zone of inhibition values of Kirby–Bauer assays to compare resistance and inhibition pattern among strains.

    Homology modeling of antibiotic resistance proteins in CRAB strains. (A) CarO from A. baumannii strains DR1, DR2, and AB067 strains were modeled using PDB 4fuv.1 as template in SWISS model ( https://swissmodel.expasy.org ) and visualized with Chimera 1.15 tool.

Phenotypic microarray analysis of A. baumannii DR1, DR2, and AB067 strains to determine metabolic utilization profiles using PM 09 to PM20 plates. Kinetic growth response curve for A. baumannii DR1 and DR2 (A) and A. baumannii DR1 and AB067 (B) strains in PM09 to PM20 plates (top panel left as PM09 to right bottom end panel as PM20). Growth kinetics of A. baumannii DR2 shown in green, compared with DR1 strain in red. Yellow indicates equivalent growth response or overlapping of DR1 and DR2 kinetic curves. Red kinetic response curves indicate a stronger response by DR1 strain, whereas green indicates a stronger growth response by DR2 strain. Heat maps of selected phenotype microarray profiles of A. baumannii DR1, DR2, and AB067 strains for antimicrobial compounds (C) , toxic (D) , and miscellaneous compounds (E) . Each dot represents Omnilog values representing all time points of bacterial growth. Omnilog values of 100 or more were considered for phenotype analysis. Gradient heat maps were generated among strains for each condition using Omnilog values in Morpheus online tool ( https://software.broadinstitute.org/morpheus ), which displayed blue color for relative lower growth, and red color represents high growth phenotype.

    Determination of MIC for polymyxin and growth inactivation assays. (A) Growth of A. baumannii DR1, DR2, and AB067 strains was evaluated in presence of different polymyxin concentrations. Optical density of growth was plotted against a range of polymyxin concentrations to determine growth and minimum inhibitory concentrations of polymyxin. (B) Resazurin microtiter assay was performed to evaluate cell viability of A. baumannii DR1, DR2, and AB067 strains in presence of various concentrations of polymyxin (PMB). After period of incubation for 15 h at 37°C, PrestoBlue, a resazurin-based cell viability reagent (Invitrogen), was added to wells containing A. baumannii DR1, DR2, and AB067 strains and control (only media) and further incubated as per manufacturer’s protocol. After period of incubation, color change from natural resazurin blue to pink (reduced form) in wells was scored to determine MIC; no color change indicates no bacterial growth. (C) Growth inhibition assay was performed in presence and absence of efflux inhibitors verapamil (VER), CCCP, and reserpine (RES) (each of 5 μg/ml) with polymyxin in DR1 (i) , DR2 (ii) , and AB067 (iii) strains. (D) Growth inhibition assay was performed in presence of tetracycline as substrate for A. baumannii strains DR1 (i) , DR2 (ii) , and AB067 (iii) , tabulated and analyzed using GraphPad Prism software.
