More evidence needed
Commenting on the study, Emily H. Adhikari, MD, assistant professor of obstetrics and gynecology at UT Southwestern Medical Center in Dallas, and medical director of perinatal infectious diseases for the Parkland Health and Hospital System, said, “These findings contribute significantly more data to an understudied area of research into factors that affect the infant gut microbiome from the earliest hours of life. Prior studies have been small and often conflicting, and the authors reference recent larger studies, which corroborate their findings.”

The data regarding whether delivery mode or antibiotic-associated differences in infant microbiomes persist remain controversial, said Dr. Adhikari. “More evidence is needed involving a more ethnically diverse sampling of patients.” In addition, prospectively evaluating vaginal seeding in a rigorously designed clinical trial setting is “imperative to understand any potential benefit and certainly to understand the potential harms of the practice. To date, this does not exist.”
The study was funded by a Canadian Institutes of Health Research grant. Mr. Dos Santos and Dr. Adhikari have disclosed no relevant financial relationships.
