Histopathological findings in wild type mink experimentally inoculated with AMDV. a Massive perivascular infiltration of mononuclear cells in the lung 8 weeks after AMDV inoculation. Pleura (asterisk). HE Hematoxylin and eosin. Scale bar 50 µm. b Massive infiltration of mononuclear cells in a portal triad of the liver 4 weeks after AMDV inoculation. Bile duct (asterisk). HE, scale bar 50 µm. c Massive interstitial infiltration of mononuclear cells in the cortex of the kidney 16 weeks after AMDV inoculation. Plasma cells (arrow), lymphocytes (arrowhead), kidney tubule (asterisk), glomerulus (g). HE, scale bar 20 µm. d Moderate non-suppurative perivascular cuffing in white matter of cerebrum 16 weeks after AMDV inoculation. Plasma cells (arrow), lymphocytes (arrowhead). HE, scale bar 20 µm
