'''Mycoplasma pneumonia''' is a form of [[bacterial pneumonia]] which is caused by bacteria of the [[Mycoplasma]] genus.
'''For patient information click [[Mycoplasma pneumonia (patient information)|here]]


==Pathophysiology==
{{CMG}} {{AE}} {{YD}} {{SSK}}
''[[Mycoplasma pneumoniae]]'' is spread through respiratory droplet transmission. Once attached to the mucosa of a host organism, ''M. pneumonia'' extracts nutrients, grows and reproduces by [[binary fission]]. Attachment sites include the upper and lower respiratory tract, causing [[pharyngitis]], [[bronchitis]] and [[pneumonia]]. The infection caused by this bacterium 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.

==Diagnosis==
==Diagnosis==
''M. pneumoniae'' infections can be differentiated from other types of pneumonia by the relatively slow progression of symptoms, a positive blood test for cold-hemagglutinins in 50-70% of patients after 10 days of infection  (cold-hemagglutinin-test should be used with caution or not at all since 50% of the tests are false-positive), lack of bacteria in a gram-stained sputum sample, and a lack of growth on blood agar.

Mycoplasma atypical pneumonia can be complicated by [[Stevens-Johnson syndrome]], [[hemolytic anemia]], [[encephalitis]] or [[Guillain-Barré syndrome]].


==Treatment==
==Treatment==
Second generation [[macrolide]] antibiotics, [[doxycycline]] and second generation [[quinolones]] are effective treatments. Disease from mycoplasma is usually mild to moderate in severity.

==History==
M. pneumoniae was historically called "Eaton's agent"<ref>[http://medical-dictionary.thefreedictionary.com/Eaton+agent Eaton agent - definition of Eaton agent in the Medical dictionary - by the Free Online Medical Dictionary, Thesaurus and Encyclopedia<!-- Bot generated title -->]</ref> because it is grown on [[Eaton's agar]].
