Prevalence of active Chlamydia trachomatis infection at the time of exploratory laparotomy for ectopic pregnancy.

Cultures of the fallopian tube, cul-de-sac, and cervix were obtained from 50 patients undergoing exploratory laparotomy for ectopic pregnancy. Chlamydia trachomatis was cultured from the cervix in four patients (8%). All the cultures from the fallopian tube or cul-de-sac were negative. Immunofluorescent stain of deparaffinized cross-sections of fallopian tube at the site of tubal involvement with the ectopic pregnancy failed to reveal any C trachomatis inclusions.
