Abstract

Aim: To analyze the impact of postpartum antibiotic (Ab) prophylaxis on the infant gut microbiome. Materials & methods: Whole metagenomic analysis was performed on breast milk and infant fecal samples collected from mother–infant pairs who belonged to two groups: an Ab group comprising mothers who had received a single course of Abs in the immediate postpartum period and a non-Ab group comprising mothers who had not received Abs. Results: The characteristic presence of Citrobacter werkmanii, an emerging multidrug-resistant uropathogen, and a higher relative abundance of genes encoding resistance to specific Abs were noted in samples from the Ab group compared with those from the non-Ab group. Conclusion: Policies regarding prophylactic Ab prescription across government and private health sectors in the postpartum period need to be strengthened.
