- S. Pneumoniae
- Staph. Aureus
- Haemophilus Influenzae
- Klebsiella
typical pneumonias generally present as:
- lobar consolidation
- alveolar exudate
- sputum production

- mycoplasma
- chlamydophila
- Coxiella
- Legionella
- viruses
atypical pneumonia is generally synonymous with…
interstitial pneumonia
neonates are particularly susceptible to pneumonia caused by…
1) strep agalactiae (grp B strep)
2) Escherichia Coli
children are particularly susceptible to pneumonia caused by
viruses
elderly are particularly susceptible to pneumonias caused by…
Gram Neg bacilli
common causes of pneumonia from childhood onward:
- S. pneumoniae
- mycoplasma
- chlamydophila
4 risk factors for pneumonia

- viral URT ifxn
- cig smoking
- COPD
infection can spread to the lungs by what 3 routes?
- inspiration
- aspiration
- hematogenous spread`
a non productive cough suggests what two types of pneumonia?
- viral
2. mycoplasmal
blood-tinged or rusty sputum suggests what type of pneumonia?
bacterial!
pneumonia causes what sound on auscultation
crackles over affected area of auscultation
pleural effusions mt accompany what type of pneumonia?
bacterial
describe CT findings in lobar pneumonia (typical pneumonia)
ifxn spreads through entire lobe, w/intra alveolar exudates (S. pneumoniae)
describe CT findings of bronchopneumonia (typical pneumonia)
patchy distribution involving more than one lobe, with distal airway inflammation and alveolar disease. Caused by a wide variety of orgs.
describe Interstitial pneumonia (atypical) CT findings
diffuse, patchy inflammation of the interstitial walls
lung abcesses (pus pockets) are most often caused by what 3 general things
bacterial pneumonia, bronchial obstruction of aspiration
bacteria that commonly cause lung abcesses (5)?
- Staphylococcus
- Pseudomonas
- Klebsiella
- Proteus
- Anaerobic bact
how do you txt lung abcess?
Abx + drainage of pus
empyema- what is it?
pus in the pleural space
what usually causes an empyeme?
staph and anaerobes
** requires drainage!

shape:
notable characteristic:
mycobacterium Tuberculosis
aerobe or anaerobe: aerobe
shape: rod
notable characteristic: ACID-FAST (colloquially termed “red snappers” bc of appearance on Ziehl-Neelson acid fast stain)
