Abstract
85 women undergoing vacuum aspiration following miscarriage were studied. At the time of vacuum aspiration, immunofluorescent stainings for detection of C. trachomatis proved positive in 5.9% of the patients. Group 8 streptococci were isolated in 7.5%, coliforms in 3.5%, and Gardnerella vaginalis in 51% of the patients. The overall frequency of postabortal pelvic inflammatory disease (PID) was 3.5%. whereas 40% of chlamydia-positive women contracted postabortal PID (p < 0.05). No significant relation between other microorganisms and postabortal PID was observed. The duration of postabortal bleeding was unrelated to the genital microbiologic flora. Based on anamnestic information about previous pregnancies and duration of preoperative bleeding it was possible to define subgroups at risk of harboring C. trachomaris and coliforms. The clinical significance of this is unknown.
