Bacterial resistance to most antibiotics in clinical use has reached alarming proportions. A challenge for modern medicine will be to discover new antibiotics or strategies to combat multidrug resistant bacteria, especially Gram-negative bacteria for which the situation is particularly critical. Vectorization of bactericide compounds by siderophores (iron chelators produced by bacteria) is a promising strategy able to considerably increase the efficacy of drugs. Such a Trojan horse strategy can also extend activity of specific Gram-positive antibiotics to Gram-negative bacteria.
