Histological section of subcutaneous adipose tissue of a 25-year–old, female fur seal (case No. 1) containing metacestode tapeworms with associated inflammation (box). The parasitic structures are characterized by a tegument (arrow) and centrally a parenchymatous matrix (asterisks) is present (A, bar = 1000 μm). Within the parenchymatous matrix of the parasite, numerous calcareous corpuscles stained with the “von Kossa” –method are present (B, bar = 100 μm). The parasite is surrounded by an inflammatory reaction composed of lymphocytes, plasma cells, macrophages and neutrophils (C, bar = 100 μm). A, C = hematoxylin and eosin.
