Discovery Leads to Way to Curb Anthrax Effect

...ll of the host’s iron is functioning in enzymes or heme containing proteins, or is safely stored, with a small amount in transit bound to a protein called transferrin. Pathogenic bacteria like anthrax must tap into our normal iron flow to grow,” he said. Bacteria have several means to capture iron from ...
