1

Acute (short/days, neutrophils, edema, no fibrosis, vasodilation & permeability, fever, leukocytosis)

Chronic (long/weeks-months, lymphocytes & plasma cells, ?edema, fibrosis, neovascularization, granulation tissue, low grade fever, anemia, wt loss)

bronchopneumonia

-atypical pneumonia

-follows distribution of bronchi & bronchioles (patchy)

-staph aureus, klebsiella (abscess formation),

e. coli, pseudomonas, nosocomial pna
