[The role of nonsporulating anaerobic bacteria in the etiology of postabortion and postpartal endometritis].

As the result of the study carried out by the authors, a conclusion has been made on the leading role of polymicrobial aerobic-anaerobic complexes, capable of producing a synergic effect, in the etiology of endometritis, anaerobic microorganisms prevailing in their importance. In the etiology of endometritis the most important organisms are bacteroids and peptostreptococci among anaerobes, enterobacteria and group D streptococci among aerobes. Anaerobic bacteria causing endometritis are most sensitive to dalacin and lincomycin, least sensitive to benzylpenicillin, resistant to aminoglycosides. The amounts of aerobic and anaerobic microflora contaminating the uterine cavity correlate with the severity of endometritis.
