ALT Mike’s infection isn’t responding to antibiotics. “Bacteria adapt fast,” his doctor says, “but LSU researchers are finding new ways to fight them—by starving them of iron.” Mike pictures his blood cells guarding yellow iron particles as sneaky green bacteria try to steal them. LSU scientists study how bacteria sense and store iron through proteins like ferredoxin and bacterioferritin. A new drug could trap iron in storage, tricking bacteria into thinking they have none and killing them off. Mike leaves hopeful—LSU research could one day save lives like his.
