RESUMO

Immunity to intracellular bacteria including Mycobacterium tuberculosis, Mycobacterium leprae, and Listeria monocytogenes depends on specific T cells. Evidence to be described suggests that CD4 alpha/beta T cells, CD8 alpha/beta T cells and gamma/delta T cells which interact with each other and with macrophages contribute to acquired resistance against as well as pathogenesis of intracellular bacterial infections.
