Which is a common cause of Pelvic Inflammatory Disease?

• A. Pelvic inflammatory disease
• B. Gonorrhea & Chlamydia
• C. E. coli
• D. Staphylococcus aureus

Answer: (B)

Pelvic Inflammatory Disease results from an infection that ascends from the cervix into the upper genital tract, causing inflammation of the uterus and fallopian tubes. The most common culprits are sexually transmitted bacteria, specifically Neisseria gonorrhoeae and Chlamydia trachomatis. These pathogens frequently infect the cervix and, if not treated, can ascend to cause PID, which is why this combination is the best answer. Other organisms like E. coli or Staphylococcus aureus can play a role in PID in certain circumstances, but they are not the typical or most frequent causes. Recognizing that gonorrhea and chlamydia are the predominant sources helps explain why they’re identified as the common cause.
