Which organism is the MOST common cause of pelvic inflammatory disease worldwide?
- A Neisseria gonorrhoeae
- B Mycobacterium tuberculosis
- C Chlamydia trachomatis ✓
- D Mycoplasma genitalium
Correct answer: C. Chlamydia trachomatis
Explanation
Chlamydia trachomatis is the most frequently isolated organism in PID globally, largely because it produces subclinical, silent infection that ascends untreated. Neisseria gonorrhoeae is the second commonest and tends to produce a more acute, symptomatic illness with higher fever and purulent discharge, which tempts students to pick it. Mycobacterium tuberculosis is an important cause in India but is not sexually transmitted and not the commonest cause of acute PID.
