Which microorganism is the MOST common cause of acute pelvic inflammatory disease worldwide?
- A Chlamydia trachomatis ✓
- B Neisseria gonorrhoeae
- C Mycoplasma genitalium
- D Bacteroides fragilis
Explanation
Chlamydia trachomatis is the most frequently identified pathogen in acute PID globally, including India. Neisseria gonorrhoeae is the strongest distractor: it produces a more acute, febrile, purulent presentation, so students associate it with classic PID, but its isolation rates are lower than those of chlamydia. PID is typically polymicrobial, with anaerobes such as Bacteroides and Mycoplasma genitalium playing secondary roles.
