Overview
Bacterial pneumonia may be due to a variety of underlying causes. The microorganisms responsible are divided into Typical and Atypical. Typical bacteria often result in a classic pneumonia whereas atypical bacteria lead to a much milder presentation often referred to as "walking pneumonia". These patients appear near normal but have extensive findings on chest x-ray.
Causes
Microorganisms
| Typical Pneumonia [1] | Atypical Pneumonia [1] |
|---|---|
| Streptococcus pneumoniae | Legionella |
| Staphylococcus aureus | Mycoplasma pneumoniae |
| Haemophilus influenzae | Chlamydia pneumoniae |
| Listeria monocytogenes | |
| Group A streptococci | Chlamydia psittaci |
| Moraxella catarrhalis | Chlamydia Trachomatis |
| Anaerobes and aerobic gram-negative bacteria |
Causes of Nosocomial and Ventilator Associated Pneumonia
- Staphylococcus aureus (MRSA)
- Streptococcus species
- Pseudomonas aeruginosa
- Escherichia coli
- Klebsiella pneumoniae
- Enterobacter species
- Acinetobacter species
Demographics
| Age Group | Most common organism |
|---|---|
| Neonates (<4 weeks old) | Group B streptococci, Escherichia coli [3], Listeria monocytogenes[4] |
| Toddlers (2 - 4 years) | Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis[4] |
| Children (4 weeks - 18 years) | Streptococcus pneumoniae, Mycoplasma pneumoniae, Haemophilus influenzae[4] |
| Adults (18 - 40 years) | |
| Adults (40 - 65 years) | |
| Elderly (>65 years) |
