Abstract

Recent isolation studies have shown Chlamydia trachomatis to be an important aetiological agent in acute salpingitis in women. The present serological study indicates that C. trachomatis is the probable aetiological agent in two-thirds of 143 women with pelvic inflammatory disease (PID). In general, high levels of chlamydial antibody were found in sera and fluids aspirated from the pouch of Douglas and such antibody titres were shown to correlate with the severity of clinically graded tubal inflammation.
