COMMENT: This work is oriented to evaluate the impact of the maternal antibiotic prophylaxis (MAP) on the abundance of Bifidobacterium spp in milk because these bacteria have been associated to infant health benefits and it is known that human milk is source of bacteria for newborn gut microbiome.
The authors detect lower levels of Bifidobacterium in the first week after delivery in the group of mothers that received antibiotic prophylaxis but at day 30±4 no differences were found in Bifidobacterium counts:
Our results suggest that MAP has a significant impact on Bifidobacterium counts in human milk, reducing this population in the first week after delivery. However, throughout the first month after delivery, the Bifidobacterium counts tend to recover, reaching similar counts to those found in no-MAP group at day 30±4 after delivery.
