Term referring to Mycoplasma pneumoniae.
Eaton in 1944 isolated the causative agent of primary atypical pneumonia. It had the capability to pass through bacterial filters and hence was considered to be a virus which was named Eaton agent. Later it was found out that Eaton agent was a bacteria and was named Mycoplasma pneumoniae.

headache
malaise
sorethroat
paroxysmal cough

radiography shows patchy consolidation of lower lobes – starting at hilum, fanning to periphery

 
Complications

myringitis bullosa, otitis – common
rashes
meningitis
encephalitis
hemolytic anemia

 
Lab diagnosis:

Inflammation of the tympanic membrane with the appearance of painful blisters. One of the diseases producing this conditions is otitis media due to mycoplasma infection.
