Bacteroides fragilis (B.f.) is an aetiological agent of gynecological and obstetrical infections. The aim of this study was to determine occurrence of B.f. in women genital tract. A total number of 118 women in labor between 38 and 43 gestation age and not demonstrating clinical symptoms of infection was examined. B.f. strains were isolated from 9 women (15.9%). More often B.f. strains were isolated from women delivering post-term and staying previously in Pregnancy Pathology Ward. It was observed that infant mean weight on the 3rd day of life was higher in the vagina. The following features of isolates were compared: presence of the capsule and agglutination of sheet erythrocytes. Differences in haemagglutination and susceptibility to antibiotics were observed.
