Show Summary Details


Mycobacterium tuberculosis complex is made up of Mycobacterium tuberculosis, Mycobacterium bovis, Mycobacterium africanum, and Mycobacterium microti.

Humans are the only natural reservoir of M tuberculosis. Mycobacterium bovis is caused by consumption of unpasteurized milk products from an infected cow. Cattle-to-human transmission also occurs. Patients with tuberculosis (TB) usually present with fever; less commonly, pleuritic chest pain, retrosternal or interscapular pain. Physical examination findings are usually normal. Hilar adenopathy is typical, often resolving in 1 year or more. Disease manifestations of other mycobacterial infection are also reviewed.
