HE, van Gieson and ISH stained sections showing chronic pathology in gill, peritoneum and intestine. a HE-stain of gill with extensive epithelial proliferation filling the space between lamellas and some cytoplasmic D. lepeophtherii proliferative stages surrounded by halo (arrow) and necrosis (arrowhead). b van Gieson-stain of granulomatous inflammation and fibrosis in the abdomen staining collagen deposits red (yellow *), D. lepeophtherii cytoplasmic proliferative stage (arrowhead) and Splendore-Hoeppli concrement (arrow). c HE-stain of invasive peritonitis in GI-wall, including D. lepeophtherii cytoplasmic proliferative stage (arrowhead) and multinucleated giant cell (arrow). d ISH of same area as in a showing proliferative stages of D. lepeophtherii stained red (arrow) in proliferative gill lesions, e ISH of same peritoneal area as in b showing proliferative stages of D. lepeophtherii stained red (arrowhead) and Splendore-Hoeppli concrement (arrow). f ISH of same intestine as in c showing proliferative stages of D. lepeophtherii stained red (arrowhead) and stratum compactum (arrow). Scale-bars: a-d, f, 50 μm; e, 10 μm
