Light photomicrograph of gills of control and exposed Nile tilapia sectioned with H&E stain: Control showing normal histological architecture comprising normally arranged gill lamellae (arrow) (a). The gills of PS-NPs exposed group showing hyperplasia of epithelial lining lamellae led to fusion of secondary lamellae (arrow), besides vacuolization of secondary lamellae (star) (b), sloughing and loss of secondary lamellae (arrow) (c). The gills of EO exposed group showing necrosis of gill lamellae (arrow), besides congestion of blood vessels (star) (d). Gills of PS-NPs + EO exposed group showing necrosis and vacuolation of gill lamellae (arrow), moreover congestion and dilation of central venous sinus (star) (e), necrosis with sloughing and desquamation of secondary lamellae (arrow) (f)
