Perturbations of bacterial lipids. Significantly perturbed lipids in A. baumannii ATCC17978 following treatment with polymyxin B (PMB, red), prochlorperazine (PCH, green) and the combination (COM, purple) for (A) 0.5 and (B) 4 h. Lipid names are putatively assigned based on accurate mass (≥0.58553-log2-fold, p ≤ 0.05; FDR ≤ 0.05). Control, untreated samples; PE, phosphoethanolamines; PG, glycerophosphoglycerols; PS, glycerophosphoserines; PC, glycerophosphocholines; PA, glycerophosphates; LysoPE, lysophosphatidylethanolamines; LysoPC, lysophosphatidylcholines; LPA, lysophosphatidic acid FA, fatty acids.
