| Other lactobacilli (group) | 146 (7.8) | 20 (13.7) | 255 (14.9) | 0.91 (0.56–1.48) | 0.700 |
| Gardnerella vaginalis | 314 (16.9) | 39 (12.4) | 236 (15.3) | 0.79 (0.55–1.13) | 0.196 |
| Mixed aerobic bacteria $ | 211 (11.3) | 34 (16.1) | 241 (14.6) | 1.12 (0.76–1.66) | 0.564 |

$ Mixed aerobic bacteria group included members of Enterobacterales, Enterococcus spp., and other aerobic bacteria, but excluded GBS and S. anginosus group of bacteria. # GBS colonization in vaginal swabs was 14.8% overall (n = 275). Note that only vaginal swabs were evaluated with the enrichment culture.
