Photomicrographs of H&E-counter stained transverse sections from the intestine of non-supplemented Nile tilapia or supplemented with biosynthesized selenium nanoparticle (SeNPs) at SeNPs0.75 mg/Kg or SeNPs1.5 mg/Kg showing no structural damage. Low magnification (X10, bar 100 µm). Control = group fed basal diet; SeNPs0.75 = group fed basal diet with the addition of 0.75 mg/kg SeNPs; and SeNPs1.5 = group fed basal diet with the addition of 1.5 mg/kg SeNPs
