Mycobacteria most commonly involve infections of the pulmonary system, but some species infect the lymphatic system and skin. Mycobacteria are gram-positive, nonmotile, acid-fast pleomorphic rods. They vary in colony morphology, pigmentation, and growth rates. Mycobacterium tuberculosis, the most important pathogenic Mycobacterium, is slow-growing and causes highly contageous, airborne respiratory disease. Tuberculosis is responsible for an estimated 2 million deaths per year worldwide.
