Viruslike inclusions in the cecal epithelial cells of Pa  agonimus kellicotti (Digenea, Troglotrematidae).
Rodlike or tubular inclusions are described from the cytoplasm and nuclear matrix of the cecal epithelial cells of Paragonimus kellicotti. These inclusions are 3.4 mu or more long, 350 A in diameter, and comprised of a wall of helically arranged subunits and a dense, possibly filar, central core. They occur in organized bundles of up to 17 members. Cells containing these inclusions manifest a series of nucleolar modifications typical of inclusions is discussed, noting especially their resemblance to known rodlike viruses from other systems.
