Pneumonia Flashcards
Cause of interstitial pneumonia
Viruses like influenza, RSV and adenovirus
Bacteria that cause atypical (interstitial) pneumonia
Mycoplasma pneumonia, Legionella, Chlamydia, Coxiella Burnetti
Patchy distribution pneumonia >1lobe
Bronchopneumonia (lobular)
Causes of Lobular pneumonia (bronchopneumonia)
S. penumonia, S. aureus, H. influenza, Klebsiella
Exacerbates COPD
H. influenzae; Moraxella catarhhalis; Legionella
acute inflamamtory infiltrates from broncioles into adjacent alveoli
Bronchopneumonia (lobular)
Intra-alveolar exudate
Lobar Pneumonia
CAP Lobar pneumonia

Alcoholic pneumonia
Klebsiella pneumonia
Most common cause of atypical pneumonia in infants
RSV
Placenta of animal
Coxiella burnetti
Post-transplant immunosupressive therapy cause of pneumonia
CMV
Most common cause of secondary pneumonia superimposed on viral pneumonia
S. aureus
4 Phases of Lobar Pneumonia
- Congestion: dilate BV and edema
- Red Hepatization
- Grey Hepatization
- Resolution: healing by type II pneumocytes
Cold hemolytic anemia (IgM)
