¹ Tinidazole was prescribed to some women in the cohort the night before surgery.

² Top five most abundant microbial community taxa identified by 454 sequencing.

³ Prophylactic tinidazole was administered to some women the night prior to surgery.

Multiple members of the Staphylococcus family were identified in some cohorts, however, identification to species level was not possible.
