Effescts of acute diclofenac exposure on intestinal histology, antioxidant defense, and microbiota in freshwater crayfish (Procambarus clarkii).

In the present study, we exposed Procambarus clarkii to different doses (0, 1, and 10 mg/L) of diclofenac (DCF). Meanwhile, we investigated the effects of exposure to DCF on intestinal histology, antioxidant defense, and microbial communities in P. clarkii.
