II. Pathophysiology: Characteristics
- Rod shaped Bacteria
- Obligate aerobic Bacteria
- Hence predisposition for the lungs (e.g. Tuberculosis)
- Acid fast organisms due to lipid rich cell walls
- Acid Fast Staining is unique to Mycobacteria and Nocardia
- Mycobacteria grow slowly in culture (up to 6 weeks)
- Many Mycobacterial species grow in clumps due to their hydrophobic, lipid rich cell walls
III. Types
- Tuberculous Mycobacteria
- Mycobacterium tuberculosis
- Mycobacterium leprae (Leprosy, Hansen's Bacillus)
- Mycobacterium Bovis
- Primarily infects cattle, but may also cause Tuberculosis in humans
- Transmitted in unpasteurized milk or dairy products from infected cattle
- May also transmitted by airborne Bacteria from infected animals
- May also spread by direct contact during meat processing
- Non-Tuberculous Mycobacteria
- Background
- Ubiquitous Bacteria found in soil and water
- Healthy patients are frequently exposed but rarely infected
- Mycobacterium Avium Complex (MAC)
- AIDS defining disease
- May also less commonly infect lungs in immunocompetent patients
- Mycobacterium Abscessus
- May affect lung, skin, soft tissue and bone
- Mycobacterium Chelonae
- May affect skin, soft tissue and bone
- May cause Keratitis in Contact Lens users
- May cause disseminated infection in Immunocompromised patients
- Mycobacterium Fortuitum
- May affect skin, soft tissue and bone
- Mycobacterium Marinum (Fish Tank Granuloma)
- Nodular Lymphangitis in those caring for fish tanks
