Pumping supplies alter the microbiome of pumped human milk: An in-home, randomized, crossover trial.

ABSTRACT:

Background

The human milk microbiome may contribute to the benefits of breastfeeding by providing bacteria to the infant gastrointestinal tract. Many women pump their milk, but the effect of pumping on the milk microbiome is unknown.

Objectives

Our objective was to determine the effects of pumping supplies on the pumped human milk microbiome.

Methods

This was an in-home, randomized, crossover trial of 2 collection methods. Women (n = 52) pumped twice within 3.5 h, once with their own breast pumps and milk collection supplies (OWN SUPP) and once with a hospital-grade pump and sterile collection supplies (STER SUPP). Pumping order was randomized. The milk microbiome was characterized by aerobic culturing and 16S ribosomal RNA gene sequencing.

Results

Milk collect
