Intestinal Inflammation, Dysfunction of Intestinal Digestion, and Disorder in the Intestinal Microbiota and Their Metabolites Caused by Oral <i>Microcystis</i> Exposure in Common Carp (<i>Cyprinus carpio</i>).

ABSTRACT: Cyanobacterial blooms are a common water pollution phenomenon worldwide now. Among them, Microcystis blooms occur most frequently internationally, and most of them can produce hepatotoxins-microcystins (MCs). When the bloom occurs in water bodies, common carp, as the top consumers in the aquatic food chain, inevitably ingest a large amount of cyanobacteria. The effects on the intestinal digestion, immunity, and microbiota of the carp remain to be revealed. In the present study, 21-day gavage exposure to Microcystis paste (equivalent to 378.25 μg/kg of MC-LR) was conducted on juvenile carp mainly to investigate the adverse effects of MCs on the fish intestinal digestion, immunity, and microbiota. The results showed that Microcystis exposure caused intestinal barrier dam
