Early Bifidobacterium breve supplementation after cesarean birth: Promise and unanswered questions

This is the authors' abstract. We don't add key points for this paper.

Cesarean delivery alters the normal route of microbial transmission from mother to infant. Compared with vaginally delivered infants, those born by cesarean section typically acquire fewer maternal gut-associated bacteria and exhibit delayed colonization by Bifidobacterium and Bacteroides, accompanied by a greater early abundance of facultative and hospital-associated microorganisms [1,2]. Whether these differences represent a transient variation in microbial development or a disruption that warrants intervention remains controversial.
