Reactive oxygen species (ROS) production by rainbow trout blood leukocytes, evaluated by nitroblue tetrazolium reduction into formazan. Fish food was supplemented for 30 days with 108 CFU of Se nanoparticle-enriched Lactiplantibacillus plantarum S14 strain (LABS14-Se0Nps) g−1 or 108 CFU L. plantarum S14 strain (LABS14) g−1. Control did not receive the bacterial strain. Bars indicate standard deviation.
