Mycoplasma pneumonia

Definition

Mycoplasma pneumonia is a type of bacterial infection that primarily affects the respiratory tract, leading to atypical pneumonia. It is caused by the bacterium Mycoplasma pneumoniae, which lacks a cell wall.

5 Must Know Facts For Your Next Test

1. Mycoplasma pneumoniae is resistant to antibiotics that target cell walls, such as beta-lactams.
2. It is often referred to as 'walking pneumonia' because symptoms can be mild enough that people do not feel the need for bed rest.
3. Diagnosis can involve serological tests like agglutination assays to detect specific antibodies against M. pneumoniae.
4. Common symptoms include a dry cough, sore throat, fever, and fatigue.
5. The infection spreads through respiratory droplets from coughing or sneezing.
