Recently, the effects of exposure to clothianidin (CLO) on the thymus and gut microbiota have become clear, but no report has examined its next-generation impacts. Pregnant C57BL/6N mice were administered a no-observed-adverse-effect-level dose of CLO until weaning. We examined CLO’s effects on the gut microbiota and immune organs of dams and their 3- and 10-week-old male offspring. CLO administration led to several alterations of the top 30 bacterial genera in the gut microbiota in dams and 3-week-old mice. Compared to controls, 10-week-old mice had more thymic Hassall’s corpuscles, and both dams and 10-week-old mice had fewer macrophages. These results suggest that fetal and lactational CLO exposure may affect the immune system and gut microbiota of the next generation.
