Study Notes
Tuberculosis Acquisition and Symptoms
- Primary mode of acquisition for tuberculosis (TB) is through inhalation of aerosolized droplets containing Mycobacterium tuberculosis.
- Common presenting symptoms of pulmonary tuberculosis include chronic cough, weight loss, night sweats, and hemoptysis (coughing up blood).
Immunocompromised Patients
- In immunocompromised patients, the leading cause of death related to TB is usually due to overwhelming disseminated disease and associated opportunistic infections.
Hallmark and Immune Response
- The hallmark of primary tuberculosis is the formation of a Ghon complex, which consists of a granuloma in the lung and lymph node involvement.
- High antigen load results in a hypersensitivity reaction, causing tissue damage and exacerbating disease progression.
Survival Mechanisms
- Mycobacterium tuberculosis has unique cell wall components, including mycolic acids, that allow it to survive phagocytosis by inhibiting the fusion of the phagosome with lysosomes.
