Effects of PM2.5 exposure during gestation on maternal gut microbiota and pregnancy outcomes

A number of studies have reported that fine particulate matter (PM2.5) exposure is associated with adverse pregnancy outcomes. Moreover, PM2.5 exposure contributes to changes of gut microbiota. However, influences of PM2.5 exposure during gestation on maternal gut microbiota and pregnancy outcomes were not well understood. Here we performed a study using mice models. Dams were exposed to PM2.5 suspension by intratracheal instillation on...
