The gut microbiota: a major player in the toxicity of environmental pollutants?

Exposure to environmental chemicals has been linked to various health disorders, including obesity, type 2 diabetes, cancer and dysregulation of the immune and reproductive systems, whereas the gastrointestinal microbiota critically contributes to a variety of host metabolic and immune functions. We aimed to evaluate the bidirectional relationship between gut bacteria and environmental pollutants and to assess the toxicological relevance of the bacteria-xenobiotic interplay for the host. We examined studies using isolated bacteria, faecal or caecal suspensions-germ-free or antibiotic-treated animals-as well as animals reassociated with a microbiota exposed to environmental chemicals. The literature indicates…
