[cytoarchitecture of the vitellaria of two monogenean species, parasites of the holocephalan fish chimaera monstrosa l. with analysis of vitelline structure in the neodermata]. | the ultrastructural features of the vitelline follicles of ectoparasitic monogenean chimaericola leptogaster leuckart, 1830 (polyopisthocotylidea, chimaericolidae) and endoparasitic calicotyle affinis scott, 1911 (monopisthocotylidea, monocotylidae), parasites of the gills and cloaca of a holocephalan fish, chimaera monstrosa l., are described. the vitelline follicles of the studied monogenean species are composed of the cells of a single type, vitellocytes at various stages of development. spec ... | 2015 | 25702500 |
ultrastructural characteristics of the caeca of basal polyopisthocotylean monogeneans of the families chimaericolidae and hexabothriidae parasitic on cartilaginous fishes. | ultrastructural differences are shown between the caecal organization in three blood-feeding polyopisthocotylean monogeneans, i.e., the chimaericolid chimaericola leptogaster from the holocephalan chimaera monstrosa and two hexabothriids, callorhynchocotyle callorhynchi from the holocephalan callorhynchus capensis and rajonchocotyle emarginata from the elasmobranch amblyraja radiata. in c. leptogaster, digestive cells and connecting syncytium, joined close to the luminal surface by septate junct ... | 2015 | 25869960 |
clamp ultrastructure of the basal monogenean chimaericola leptogaster (leuckart, 1830) (polyopisthocotylea: chimaericolidae). | the ultrastructure of the haptoral clamps of the chimaericolid monogenean chimaericola leptogaster, a basal polyopisthocotylean from the gills of a holocephalan fish, is described. these clamps are characterized by the presence of two muscle blocks interrupted mid-anteriorly and mid-posteriorly and different kinds of hard structures: a single median and paired lateral sclerites embedded in the clamp wall; six spine-like structures directed towards the clamp lumen; and electron dense surface stru ... | 2014 | 25112214 |
ultrastructural characteristics of the vaginae of the basal monogenean chimaericola leptogaster (leuckart, 1830). | in the first study of the vaginal ultrastructure of any monogenean, the paired vaginae of chimaericola leptogaster, a basal polyopisthocotylean from the gills of a holocephalan, are described. each vagina opens laterally. a unique feature of this relict parasite is a short vagino-intestinal connecting duct, the lining of which is separated by septate junctions from the linings of the vagina and the intestine. after giving rise to this vagino-intestinal duct, each vagina travels in a posterior di ... | 2013 | 24043615 |
