With a fluorophore label, these peptide probes selectively stain colistin-resistant bacteria at sub-to-low micromolar concentrations. The bacterial staining is minimally inhibited by the presence of serum proteins or even blood serum. Mechanistic studies indicate that our peptide probes bind colistin-resistant bacteria primarily by targeting PE-modified lipids. However, some species-specific features of the cell surface can also contribute to the peptides' association to bacterial cells. Further elucidation of such cell sur
