A 35-year-old woman presents with a 4-month history of constant pelvic pain, dyspareunia, and a mucopurulent vaginal discharge. Pelvic examination reveals cervical motion tenderness and bilateral adnexal tenderness. Temperature is 38.4°C. The MOST common causative organisms of pelvic inflammatory disease (PID) in sexually active women are:

• A Escherichia coli and Klebsiella pneumoniae
• B Neisseria gonorrhoeae and Chlamydia trachomatis ✓
• C Staphylococcus aureus and Streptococcus agalactiae
• D Trichomonas vaginalis and Candida albicans

Explanation

Pelvic inflammatory disease is most commonly caused by sexually transmitted organisms, predominantly Neisseria gonorrhoeae and Chlamydia trachomatis, either alone or in combination. Polymicrobial infection including anaerobes and Gram-negative facultative bacteria (including G. vaginalis) is also frequently involved. The clinical triad of cervical motion tenderness, uterine tenderness, and adnexal tenderness is the minimum diagnostic criteria.
