a The histopathological alterations of common carp fish intestine after the exposure to B-AgNPs at 0.03 mg/L concentrations. (↑) Degeneration, necrosis, and loss of epithelium cells on the top of villi in the small intestine, (↑) the increased number of lymphocytes. b The histopathological alterations of common carp fish intestine after the exposure to B-AgNPs at 0.06 mg/L. (↑) Necrosis, and shedding, lamina propria disintegrate in mucosal cells (↑) lymphocytes infiltration. c The histopathological alterations of common carp fish intestine after the exposure to B-AgNPs at 0.09 mg/L. (↑) Degeneration, necrosis, and cell lysis in villi of the intestine, (↑) increased lymphocytes. The tissues were stained using eosin and magnified with × 400
