Mycoplasma pneumonia

  • Causes “walking pneumonia”  (relatively slow progression of symptoms). 
  • Spread through respiratory droplet transmission (attachment sites include: upper and lower respiratory tract, causing pharyngitis, bronchitis, and pneumonia).
  • The infection is called atypical pneumonia because of its protracted course and lack of sputum production and wealth of extra-pulmonary symptoms.
  • Chronic mycoplasma infections have been implicated in the pathogenesis of rheumatoid arthritis and other rheumatological diseases.
