Occurrence of Bacteroidaceae in vaginal secretions of healthy pregnant women and patients with colpitis.

The frequency of gram-negative non-sporing anaerobes with possible clinical significance was studied in healthy pregnant women and in patients with non-Candida vaginitis. Only 4% of the healthy pregnant women studied yielded anaerobes of the family Bacteroidaceae. However, the incidence of Bacteroidaceae in 58 patients with colpitis was 53.5%. The predominant anaerobic species was Bacteroides oralis.
