title: Viruslike inclusions in the cecal epithelial cells of Pa  agonimus kellicotti (Digenea, Troglotrematidae).
abstract: 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.
