Mycobacterium leprae, the causative agent of leprosy, does not grow in vitro. We describe an easy to follow protocol to prepare a bacillary suspension to ensure the maintenance of large quantities of M. leprae for a variety of applications. Protocols for propagation by mouse footpad inoculation, evaluation of viability, freezing and thawing bacillary stock are described in detail.
