Read MoreMany pathogenic bacteria use “stealth siderophores” to steal iron from humans. Find out how scientists are stopping bacteria from stealing our iron. By Ada Hagan As we discussed last time, bacteria that infect the human body face a major challenge, iron, which is essential for bacterial growth, is hard to obtain from human tissues. Many pathogenic bacteria solve this problem by deploying “stealth siderophores,” which steal iron from human iron-binding proteins while evading our defenses. In the battle between humans and pathogenic bacteria, our best weapons—antibiotics—are being weakened by widespread…
Read MoreHuman cells need iron, and so does bacteria. Bacteria make siderophores, scavenger molecules that leave the cell to poach iron from hosts.
