Abstract
Phagocytosis of tubercle bacilli by antigen-presenting cells in human lung alveoli initiates a complex infection process byMycobacterium tuberculosisand a potentially protective immune response by the host.M. tuberculosishas devoted a large part of its genome towards functions that allow it to successfully establish latent or progressive infection in the majority of infected individuals. The failure of immune-mediated clearance is due to multiple strategies adopted byM. tuberculosisthat blunt the microbicidal mechanisms of infected immune cells and formation of distinct granulomatous lesions that differ in their ability to support or suppress the persistence of viableM. tuberculosis. In this paper, current understanding of various immune processes that lead to the establishment of latentM. tuberculosisinfection, bacterial spreading, persistence, reactivation, and waning or elimination of latent infection as well as new diagnostic approaches being used for identification of latently infected individuals for possible control of tuberculosis epidemic are described.
