Photomicrograph of H&E-stained sections from liver and spleen of Nile tilapia supplemented with green synthesized selenium nanoparticles (SeNPs) at 0, 0.75, and 1.5 mg SeNPs/kg for 8 weeks. Liver shows normal histological appearance of hepatocytes, sinusoids, hepatopancreas (thick black arrows) in all groups. Spleen shows histological appearance of white pulp and red pulp including melanomacrophage centers (thick black arrows). However, slightly enlarged melanomacrophage centers are observed in group SN2 (thick black arrows) compared to other groups. Low magnification X: 100 bar 100.
