🔵 🔍📝 The influence of pre- and postnatal exposure to air pollution and green spaces on infant’s gut microbiota: Results from the MAMI birth cohort study 👨🔬 Adrià Cruells, Raúl Cabrera-Rubio, Mariona Bustamante, Dolors Pelegrí, Marta Cirach, Pol Jimenez-Arenas, Anna Samarra, Cecilia Martínez-Costa, Maria Carmen Collado, Mireia Gascon Link in our BIO 🔗 https://linktr.ee/semipyp 🌿🔬 Results Acute exposure in the first week of life and chronic postnatal exposure to NO2 were associated with a reduction in microbial alpha diversity, while the effects of green space exposure were not evident. Acute and chronic (prenatal or postnatal) exposure to NO2 resulted in increased abundance of Haemophilus, Akkermansia, Alistipes, Eggerthella, and Tyzerella populations, while increasing green space exposure associated with increased Negativicoccus, Senegalimassilia, and Anaerococcus, and decreased Tyzzerella and Lachnoclostridium populations. 🌱🦠 Discussion We observed a decrease in the diversity of the gut microbiota and signs of alteration in its composition among infants exposed to higher levels of NO2. 🌍🌳 Increasing green space exposure was also associated with changes in gut microbial composition. Further research is needed to confirm these findings. #NO2 #AirPollution #GutHealth #Microbiota #GreenSpace #InfantHealth #EnvironmentalHealth #PublicHealth
