First spermatological data on the digenean genus Ityogonimus derived from the description of sperm characters of Ityogonimus ocreatus (Brachylaimidae…

Abstract The present study describes the ultrastructural organization of the spermatozoa of the brachylaimid digenean Ityogonimus ocreatus (Ityogoniminae) by means of transmission electron microscopy (TEM). Live digeneans were collected from the digestive tract of an Iberian mole Talpa occidentalis (Eulipotyphla, Talpidae) captured accidentally during a vole pest control campaign in Priesca (Asturias, Spain). The TEM study reveals that the I. ocreatus sperm are filiform, tapered at both extremities, and have two 9+'1' trepaxonematan axonemes, external ornamentation of the plasma membrane associated with cortical microtubules, spine-like bodies, two bundles of parallel cortical microtubules …
Immunology and Pathology of Intestinal Trematodes in Their Definitive Hosts
2006
This review examines the significant literature on the immunology and pathology of intestinal trematodes in their definitive hosts. We emphasize information on selected species in six families for which the literature on these topics is extensive. The families are Brachylaimidae, Diplostomidae, Echinostomatidae, Gymnophallidae, Heterophyidae, and Paramphistomidae. For most of these families, coverage is considered under the following headings: (i) background; (ii) pathology of the infection; (iii) immunology of the infection; (iv) immunodiagnosis; and (v) human infection. Some of these heading have been subdivided further, based on the literature available on a particular topic. Following t…
The genus Scaphiostomum Braun, 1901 (Trematoda: Brachylaimidae): A systematic review and description of Scaphiostomum palaearcticum n. sp.
1986
A systematic review of the genus Scaphiostomum Braun, 1901 (Trematoda: Brachylaimidae) is presented. Its diagnosis is emended and its position within the subfamily Brachylaiminae Joyeux & Foley, 1930 is established. The subfamily Scaphiostominae Yamaguti, 1958 is considered a synonym of the Brachy-laiminae. Scaphiostomum comprises the following species: S. illatabile Braun, 1901 (type species) from birds in South America, S. pancreaticum McIntosh, 1934 and S. microti (Kruidenier & Gallicchio, 1959) n. comb., both from rodents in North America, and S. palaearcticum n. sp. from rodents in the Balearic Islands (Spain). Scaphiostomum sp. of Lim, 1967 from rodents in Malaysia probably constitute…
