Study Notes
Most Common Bacteria Causing Pneumonia
- Streptococcus pneumoniae: The most frequent cause of pneumonia in adults outside of a hospital setting.
- Haemophilus influenzae: Often found in older individuals and those who smoke.
- Mycoplasma pneumoniae: Commonly seen in younger patients and can present with atypical symptoms.
- Staphylococcus aureus: More commonly seen in severe cases, sometimes after influenza infection.
First-Line Pneumonia Treatment for Adults
- Outpatient (No underlying medical conditions): Amoxicillin, doxycycline, or azithromycin (if resistance to macrolide antibiotics is not a concern).
Common Pneumonia Pathogens
- Streptococcus pneumoniae: The most common bacterial cause of pneumonia in adults, often acquired in the community.
- Haemophilus influenzae: Often occurs in older adults and smokers.
- Mycoplasma pneumoniae: Commonly seen in younger patients and often presents atypically.
- Staphylococcus aureus: Usually involved in severe pneumonia cases, potentially developing after influenza.
First-Line Treatment for Bacterial Pneumonia
-
Adults (Outpatient, No Co-morbidities):
- Amoxicillin, doxycycline, or azithromycin are preferred first-line options.
- Azithromycin is recommended if macrolide resistance is a concern.
Common Bacterial Pneumonia Pathogens
- Streptococcus pneumoniae: Most frequent cause of pneumonia acquired in the community (outside of a hospital setting) for adults.
- Haemophilus influenzae: Commonly found in individuals with a history of smoking or those in the older age group
- Mycoplasma pneumoniae: Typically seen in younger individuals and can present in atypical ways.
- Staphylococcus aureus: Often observed in severe pneumonia cases, sometimes developing after influenza infection.
First-Line Treatment for Bacterial Pneumonia
-
Adults:
- Outpatient setting (no underlying health conditions): Amoxicillin, doxycycline, or azithromycin (consider macrolide resistance).
Pneumonia-Causing Bacteria

First-Line Treatment for Bacterial Pneumonia
- Adults with pneumonia in the outpatient setting and without underlying health conditions can be treated with amoxicillin, doxycycline, or azithromycin.
- Azithromycin is a preferred choice if macrolide resistance is a concern.
