Experiments will be carried out in pursuit of the original objectives of this research: 1. to screen drugs for activity against Mycobacterium leprae in mice; 2. to carry out pharmacologic studies in mice and other species, of drugs previously shown to be active; and 3. to carry out studies of M. leprae itself and of host-parasite relationships in the M. leprae-infected mouse. Among the studies to be carried out are the following: 1. immunologic studies of delayed-type hypersensitivity and lymphocyte stimulation in response to lepromins and leprolins in mice infected with M. leprae; 2. studies of activated macrophages from the foot pads of mice similarly infected; 3. studies of mice lymphadenectomized before and during infection with M. leprae; 4. studies concerning synergy between the dihydrofolate reductase inhibitors and dapsone in M. leprae-infected mice; 5. studies intended to perfect and utilize a bioassay for rifampin in conjunction with a recently developed chemical assay for this drug.
