Dysbiosis of fish gut microbiota associated with helminths parasitism and PAHs exposure. Dysbiosis of fish gut microbiota associated with helminths parasitism and PAHs exposure

We simultaneously investigated the effects of Polycyclic Aromatic Hydrocarbons (PAHs) and a common acanthocephalan intestinal parasite (Pomphorhynchus sp.) on the gut microbial flora of a freshwater fish, the European chub (Squalius cephalus). Individuals naturally infected or not with the parasite were exposed to PAHs at concentrations similar to those previously measured in wild populations from an urbanized watershed.

本研究同时探究了多环芳烃（Polycyclic Aromatic Hydrocarbons, PAHs）与一种常见棘头虫肠道寄生虫（Pomphorhynchus sp.）对淡水鱼类欧洲雅罗鱼（Squalius cephalus）肠道微生物菌群的影响。研究将自然感染与未感染该寄生虫的实验个体暴露于浓度与此前在城市化流域野生种群中测得的PAHs水平相近的环境中。
