Interactions between gut microbes and anthropogenic pollutants have been under study. The authors investigated the effects of larval exposure to polychlorinated biphenyl 126 (PCB‐126) on the gut microbial communities of tadpoles and frogs. Frogs treated with PCBs exhibited increased species richness in the gut and harbored communities significantly enriched in Fusobacteria. These results suggest that anthropogenic pollutants alter gut microbial populations, which may have health and fitness consequences for hosts. Environ Toxicol Chem 2015;34:1113–1118. © 2015 SETAC
