Abstract
A method and composition are provided for treating intracellular pathogens that reside in phagosomes. The compositions include antibiotics which are conjugated with transferrin or other ligands to form conjugates that target membrane-bound pathogens. The conjugates are selectively taken up by infected phagosomes. Conjugates are provided which utilize transferrin as the targeting ligand for treating mycobacterium which reside in membrane-bound phagosomes.
