Impact of gestational diabetes mellitus in gut and human breast milk microbiome in Colombian women and their infants
Sandra Y. Valencia-Castillo, Mayte J. Hernández-Beza, Irisbeth Powell-Cerda, Erika Acosta-Cruz, Guadalupe C. Rodríguez-Castillejos, Fernando Siller-López, Humberto Martínez-Montoya
Rev Argent Microbiol. 2025;57:14-23
Highlights

  • Our study revealed noticeable differences in the gut microbiome of women with GDM.

  • In GDM women's gut, Bifidobacterium, Serratia, and Sutterella were in low abundance.

  • The diversity and abundance of gut bacteria in GDM infants are similar to that of their mothers.

  • The analysis of GDM HBM showed Sutterella, Serratia, and Lactococcus in low abundance.

  • Our results suggest that GDM women could lead to dysbiosis in breast-fed infants.
