Mycoplasma pneumoniae can cause illness when it adheres to the epithelial cells of which part of the human body?

• A. urinary tract
• B. gastrointestinal tract
• C. respiratory tract

Answer: (C)

Verified step by step guidance

1. Understand that Mycoplasma pneumoniae is a type of bacteria known for causing respiratory infections, particularly atypical pneumonia.
2. Recall that the respiratory tract includes the nose, throat, trachea, bronchi, and lungs, which are common sites for respiratory pathogens to adhere and cause illness.
3. Recognize that Mycoplasma pneumoniae adheres specifically to the epithelial cells lining the respiratory tract, which allows it to colonize and cause infection.
4. Eliminate other options such as the urinary tract, gastrointestinal tract, and skin, as Mycoplasma pneumoniae is not typically associated with infections in these areas.
5. Conclude that the correct site of adherence and infection for Mycoplasma pneumoniae is the respiratory tract.
