initially: mild cough, and mild fever
Pathogen and virulence factors
Cause: mycobacterium TB
Presence of mycolic acid (waxy lipid)- gives bacteria unique features

protection from phagocytic lysis
capable of intracellular growth
resistance to many antimicrobial drugs and gram staining
Pathogenesis
Spread via inhalation or respiratory droplets
3 types
Primary TB
Secondary TB
Disseminated TB
Dx
