The methods of the invention can be used to treat mycobacterial infections, or
any disease or disorder that is caused by (or aggravated by) an intracellular pathogen.
Accordingly, the invention features methods for treating a subject who has a disorder
that is associated with an intracellular pathogen by administering, to a subject,
a molecular conjugate that includes a photosensitizer (a term used herein to refer
to a light activatable compound) and a targeting moiety, the targeting moiety being
capable of targeting the conjugate to the intracellular pathogen.
