“Background Tuberculosis is still one of the leading causes of mortality throughout the world. The HIV/AIDS pandemic, the deterioration of public health systems in developing countries, and the emergence of multi-drug resistance of untreatable forms of tuberculosis have further contributed to that spread. Infection by the causative agent of tuberculosis, Mycobacterium tuberculosis, is achieved by strategies involving uptake and replication of the bacterium in host macrophages and the weakening or modification of the host immune response [1, 2].
