Mycoplasma pneumoniae is a type of bacteria that causes respiratory infections in humans. It is a common cause of community-acquired pneumonia, particularly in younger individuals. Mycoplasma pneumoniae infections can also cause bronchitis, pharyngitis, and other respiratory illnesses. This bacteria is known for its ability to evade the body's immune response and can lead to persistent infections if left untreated. Diagnosis of Mycoplasma pneumoniae infections can be challenging, as it does not grow well in standard laboratory cultures. Treatment typically involves antibiotics, such as macrolides or tetracyclines.
