What type of pneumonia is caused by Mycoplasma pneumoniae?

Mycoplasma pneumoniae is primarily associated with atypical pneumonia, also known as "walking pneumonia." This type of pneumonia typically presents with milder symptoms compared to typical bacterial pneumonia, making patients less likely to seek immediate medical attention. Atypical pneumonia caused by Mycoplasma is characterized by a gradual onset of symptoms, such as a dry cough, low-grade fever, and malaise.

Mycoplasma pneumoniae is unique because it lacks a cell wall, which differentiates it from other more common bacteria that cause typical pneumonia. This characteristic contributes to the distinct clinical presentation and the way it's treated, as many standard antibiotics that target cell wall synthesis are ineffective against it. Additionally, atypical pneumonia can also be caused by other organisms, including viruses and certain bacteria, but Mycoplasma pneumoniae is a classic example within this classification.

The other options do not accurately reflect the classification of pneumonia caused by this pathogen. For instance, viral pneumonia typically involves influenza or respiratory syncytial virus (RSV), while typical pneumonia tends to be caused by organisms like Streptococcus pneumoniae, which leads to more severe symptoms and is treatable with standard antibiotics. Chronic pneumonia refers to pneumonia that persists over a longer duration, often
