Mycobacterium Avium Complex (MAC)
Presents similarly to TB and is acquired from soil, birds, or other animals |

The test for TB.
|
PPD, purified protein derivative
Detect a delayed type hypersensitivity rxn. Rule of 5's 5-Immunocompromised 10-normal positive 15- |
|
|
Infection can result in the involvement of vertebrae (Pott's Disease) with spread to form a psoas abscess and, in immunocompromised patients, overwhelming miliary dissemination
|
Mycobacterium TB
Although rare in the US, incidences of infections are increasing in immunocompromised patient and urban populations, with high incidence of multidrug-rsistant strains. |
|
|
The classic presentation of infection with this organism includes fever, night sweats, fatigue, and weight loss.
|
Mycobacterium TB
Presents similarly to other granulomatous infections such as histoplasmosis or coccidioidomycosis. |
|
|
Primary infection results in subpleural parenchymal lesions and enlarged caseous lymph nodes (Gohn complex) and reactivation can result in cavitary lesions in the upper lung lobes
|
Myobacterium TB
Dx: confirmed by finding Acid-Fast bacilli in the sputum or in cultures that take several weeks to grow. |
|
|
Infection results in the destruction of skin and cartilage, resulting in a leonine facies and limb deformities.
|
Mycobacterium Leprae
Hansen disease, presents as a spectrum between 2 extremes, from Tuberculoid leprosy associated with a good prognosis to Lepromatous Leprosy, in which numerous acid-fast bacilli are stuffed in macrophages = Lepra Cells |
|
|
Infection results in the destruction of peripheral nerves, resulting in anesthesia followed by atrophy and autoamputation.
|
Mycobacterium Leprae
This acid fast bacilli has a long generation time, approximately 13 days, and cannot be cultivated in the laboratory |

|
Impossible to grow in culture; only grows on footpads of mice, armadillos and monkeys.
Grows best on cool body parts. |
Mycobacterium Leprae
Tx: Dapsone |

|
The Lepromin skin test is similar to what and what is it used for?
|
Similar to PPD.
Measures the ability of the host to mount a delayed hypersensitivity reaction against antigens of Mycobacterium Leprae NOT DIAGNOSTIC |
