1
Q
What is Tuberculosis (TB)?
A
TB is a recurrent, chronic, infectious disease caused by Mycobacterium tuberculosis. Secondary lesions may affect the kidneys, genitalia, bones, and brain.
2
Q
How does TB infect the lungs and what is the initial immune response?
A
Droplets with M. tuberculosis enter the lungs and implant in an alveolus or bronchiole (usually in upper lobes), causing an inflammatory response with neutrophils and macrophages.
3
Q
What forms when phagocytes cannot destroy the TB bacilli?
A
A tubercle (sealed colony of bacilli) forms. Within it, infected tissue dies forming a cheese-like center (caseation necrosis).
4
Q
What differentiates Latent TB from Active TB?
A
In Latent TB, bacilli remain encapsulated and harmless. If the immune system weakens, the tubercle may rupture, leading to Active TB.
5
Q
What is Reactivation Tuberculosis?
A
When a previously healed TB lesion reactivates due to age, disease, or immunosuppressive drugs.
6
Q
What are severe forms of TB?
A
Miliary TB: widespread blood spread, affecting lungs, bone marrow, multiple organs; may lead to anemia.
TB Meningitis: affects the brain, causing headaches, vomiting, behavioral changes, coma.
Skeletal TB: spreads to vertebrae (Pott’s disease), joints, causing kyphosis, pain, joint destruction.
Genitourinary TB: affects urinary/reproductive organs, causing UTI-like symptoms, may cause infertility.
7
Q

Airborne precautions in healthcare
Early ID/isolation of cases
BCG vaccine in high-prevalence countries
9
Q
What is the Tuberculin Skin Test (TST/Mantoux Test)?
A
