The pollutants due to effect on the immune system of fish increase fish sensitivity to pathogens. Diazinon is one of the most used organophosphates pesticide in many agricultural areas. This study aimed to evaluate the effect of diazinon on the immune system of rainbow trout (Oncorhynchus mykiss) and application of Milk thistle plant, Vitis vinifera extract to reduce the adverse effects of this pesticide on its immune system. The reduction in the level of plasma peroxides, IgM, total complement and lysozyme were observed in fish exposed to diazinon showing its effect on the fish's immune system. No significant difference between control group and fish fed by Milk thistle plant extract and exposed to diazinon can reflect protective impact of Milk thistle plant extract on the immune system of rainbow trout by eliminating the free radicals and boosting the immune system.
