WebM. leprae has evolved a variety of mechanisms to avoid macrophage bactericidal mechanisms. These result in the persistence of bacilli and the release of cytokines leading to chronic granulomatous inflammation. WebM. leprae has a very small genome, indicating that it depends on host mechanisms for growth and replication. It is an obligate intracellular organism and expresses phenolic glycolipid 1 (PG1) on its outer capsule, which may decrease free radical formation and, therefore, help the organism survive host defenses.
