Efficacy of different antibiotics in the treatment of pelvic inflammatory disease.

A total of 40 patients with acute pelvic inflammatory disease (APID) were studied over a period of 7 months; one aim was to evaluate the use of different antibiotics in treatment. The most important findings were: (i) most patients had a polymicrobial aetiology for their APID; (ii) Chlamydia trachomatis and the anaerobic bacteria were the most common organisms encountered; and (iii) tetracycline plus metronidazole is probably the best combination therapy for APID.
