一项针对 2,540 名女性在三年内怀孕期间携带 B 族链球菌的纵向前瞻性研究进行了。 18% 的女性通过肛门直肠培养记录有携带，4% 通过阴道培养记录，13% 通过同时获得的肛门直肠和阴道培养记录（总体携带率为 35%）。每年的运输率和模式几乎相同。在 754 名女性的妊娠中期和晚期的连续培养中，携带率分别为 31% 和 28%；只有 17% 的女性在两个妊娠期都是携带者。 (1) 当最初的肛门直肠拭子呈阳性时，持续携带最常见，(2) 发生从肠道传播到阴道，(3) 肠道通常是先前培养结果阴性的患者的主要感染部位。肠道似乎是 B 族链球菌的主要储存库，也是孕妇阴道或泌尿生殖道定植的可能来源。
A longitudinal, prospective study of carriage of group B streptococci during pregnancy was conducted in 2,540 women over a three-year period. Carriage was documented in 18% of the women by anorectal culture, in 4% by vaginal culture, and in 13% by simultaneously obtained anorectal and vaginal cultures (overall carriage rate, 35%). The rate and pattern of carriage were nearly identical from year to year. In sequential cultures in the second and third trimesters of 754 women, carriage rates were 31% and 28%, respectively; only 17% of the women were carriers in both trimesters. (1) Persistence of carriage was most common when the initial anorectal swabs were positive, (2) spread from the intestinal tract to the vagina occurred, and (3) the intestinal tract was commonly the primary site of acquisition in patients with previously negative cultures. The intestinal tract appears to be a primary reservoir for group B streptococci and the likely source of vaginal or urogenital colonization in pregnant women.
