Study Notes
Rickettsia
- Gram-negative cocci.
- Transmitted by ticks (Rocky Mountain Spotted Fever) or body lice (Epidemic Typhus).
- Causes fever, headache, malaise, vascular injury, and rash.
- Can be fatal without treatment.
- Treated with antibiotics such as doxycycline.

- Symptoms vary depending on the specific disease, but often include fever, enlarged lymph nodes, rash, and pain.
- Mild disease cases are treated with Z-Pack, while serious infections require active antibiotics.
