Larval exposure to polychlorinated biphenyl 126 (PCB‐126) causes persistent alteration of the amphibian gut microbiota

0
Interactions between gut microbes and anthropogenic pollutants have been understudied. The authors investigated the effects of larval exposure to polychlorinated biphenyl 126 (PCB‐126) on the gut microbial inventories of tadpoles and frogs. PCB‐treated frogs 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. This article is protected by copyright.
