Infographic: Maternal Microbiota Has Lasting Effects on Offspring
Carolyn A. Thomson and Kathy D. McCoy | Aug 1, 2021
Work in rodents shows that the bacteria living in a mother’s gut can produce immunomodulatory metabolites and influence the production of maternal antibodies—both of which can affect her offspring’s development.
The Role of Mom’s Microbes During Pregnancy
Carolyn A. Thomson and Kathy D. McCoy | Aug 1, 2021
Bacteria in the gut influence the production of antibodies and themselves secrete metabolites. In a pregnant woman, these compounds may influence immune development of her fetus.
