Differences between bacterial pneumonia and mycoplasma pneumonia

Bacterial pneumonia and mycoplasma pneumonia mainly differ in terms of causative pathogens, clinical manifestations, and treatment medications. Bacterial pneumonia is a lung infection caused by specific bacteria, while mycoplasma pneumonia is an acute respiratory infectious disease caused by Mycoplasma pneumoniae. Both bacterial pneumonia and mycoplasma pneumonia require prompt treatment to prevent worsening of the condition.

1. Different Pathogens

Bacterial pneumonia is commonly caused by Gram-negative bacilli and Gram-positive cocci. Mycoplasma pneumonia refers to a pathogen that causes mycoplasma pneumonia in humans. It is an organism intermediate between bacteria and viruses—smaller than bacteria but larger than viruses—and possesses many characteristics of bacteria.

2. Different Clinical Manifestations

Patients with bacterial pneumonia usually have predisposing factors such as exposure to cold or fatigue before onset. They typically present with cough and sputum production, or experience worsening of pre-existing respiratory symptoms. Mycoplasma pneumonia is an acute inflammatory change in the respiratory tract and lungs caused by mycoplasma, often accompanied by pharyngitis and bronchitis. Symptoms primarily include fatigue, sore throat, headache, cough, fever, loss of appetite, diarrhea, muscle pain, and ear pain.

3. Different Treatment Medications

Bacterial pneumonia is generally treated with antimicrobial agents such as penicillin, levofloxacin, and gentamicin. Mycoplasma pneumonia is a type of self-limiting disease with certain autoimmune features. Although it can resolve on its own, antibiotic use can help alleviate symptoms, shorten the duration of illness, and reduce complications.
