 Cephodericol is a new type of antibiotic that has been approved for treating difficult-to-treat infections caused by multi-drug-resistant bacteria such as Pseudomonas aeroginosa, Acinetobacter bomanii, and enterobacterils. This drug works by binding to iron in the bacterium cells, which causes them to die. Despite its effectiveness, some strains of these bacteria are already developing resistance to it.
