| influence of host weight, sex and reproductive status on helminth parasites of the wild rabbit, oryctolagus cuniculus, in navarra, spain. | a study was carried out in navarra (northern spain) on the influence of the weight, sex and reproductive status (lactant, pregnant or lactant + pregnant females and testicular weight for males) of the wild rabbit (oryctolagus cuniculus) on two cestodes species: andrya cuniculi and mosgovoyia ctenoides and four intestinal nematodes: graphidium strigosum, trichostrongylus retortaeformis, nematodiroides zembrae and dermatoxys hispaniensis. a significantly higher prevalence of a. cuniculi was detect ... | 1999 | 10526414 |
| helminths of the wild rabbit (oryctolagus cuniculus) in macaronesia. | two hundred and four rabbits from 8 macaronesian islands (pico, san jorge, san miguel, terceira, and flores from azores archipelago; tenerife and alegranza from canary islands; and madeira from madeira archipelago) were examined for helminth parasites between 1995 and 2000. three species of cestodes, taenia pisiformis (larvae), andrya cuniculi, and mosgovoyia ctenoides, and 5 species of nematodes, trichuris leporis, graphidium strigosum, trichostrongylus retortaeformis, passalurus ambiguus, and ... | 2003 | 14627142 |
| parasitic helminths of the wild rabbit, oryctolagus cuniculus, in different bioclimatic zones in tenerife, canary islands. | faunistic and ecological analyses of the wild rabbit helminth fauna were undertaken in tenerife island (canary islands). rabbits were collected between 1998 and 2000 in seven bioclimatic zones in tenerife selected by orientation and altitude. five parasite species were identified, three cestodes (taenia pisiformis (larvae), andrya cuniculi and mosgovoyia ctenoides) and two nematodes (trichostrongylus retortaeformis and passalurus ambiguus). taenia pisiformis presented an irregular distribution w ... | 2003 | 14627446 |
| an ultrastructural study of embryonic envelope formation in the anoplocephalid cestode mosgovoyia ctenoides (railliet, 1890) beveridge, 1978. | in this study the ultrastructural aspects of egg envelope formation in the anoplocephalid cestode mosgovoyia ctenoides are described. in the early stage of oncospheral morphogenesis, formation of three following primary embryonic envelopes takes place: (1) the capsule, (2) the outer envelope, and (3) the inner envelope. the capsule is formed from the vitellocyte material. two macromeres contribute to the formation of the outer envelope and three mesomeres take part in the formation of the inner ... | 2005 | 15678355 |
| concentration of some toxic elements in oryctolagus cuniculus and in its intestinal cestode mosgovoyia ctenoides, in dunas de mira (portugal). | the need for sentinel organisms reflecting small-scale changes in heavy metal pollution of different habitats has been previously stated and the role of terrestrial mammalian parasites has been pointed out as an important field of research aiming at the potential use of parasitic models as bioindicators. the scope of the present study was to assess the concentration of some toxic (cd, pb, as and hg) elements in dunas de mira (natura 2000 ptcon055) while testing the model constituted by the wild ... | 2005 | 15993684 |
| ultrastructure of the tegument of the anoplocephalid cestode mosgovoyia ctenoides (railliet, 1890) beveridge, 1978. | the tegument of the mature proglottids of m. ctenoides was examined by means of tem. the tegument of this species consists of two layers: (1) the external cytoplasm, and (2) the tegumental perikarya situated in the cortical parenchyma. the tegument surface is covered by typical microtriches. the anucleated external layer of cytoplasm is rich in vesicles of different shape and electron-density, but it lacks mitochondria. large pore canals penetrate the external cytoplasmic layer. this layer is se ... | 2004 | 16865971 |
| spermiogenesis and spermatozoon ultrastructure of the cestode mosgovoyia ctenoides (cyclophyllidea: anoplocephalidae), an intestinal parasite of oryctolagus cuniculus (lagomorpha: leporidae). | ultrastructural characters in spermiogenesis and spermatozoa are considered important tools to elucidate the phylogenetic relationships within the platyhelminthes. in the anoplocephalidae, ultrastructural data refer to the spermatozoon of 14 species, whereas data on spermiogenesis refer to only 7 species. the present study focused on the spermiogenesis and spermatozoon of the anoplocephalid cestode mosgovoyia ctenoides, as revealed by transmission electron microscopy. type iv spermiogenesis was ... | 2006 | 16995386 |
| cellular organization of the oncosphere of mosgovoyia ctenoides (cestoda: anoplocephalidae). | the ultrastructure of the infective oncosphere of the cestode mosgovoyia ctenoides (anoplocephalidae) is described. the surface of the infective oncosphere is covered by a thin cytoplasmic layer of tegument connected by a narrow cytoplasmic process with the binucleate subtegumental cell, situated deeper in the body. below the basal matrix of the cytoplasmic layer of the tegument are situated wide bands of the peripheral, somatic musculature responsible for body movements. the 3 pairs of hooks an ... | 2006 | 17152934 |
| the helminth parasites of the wild rabbit oryctolagus cuniculus and their effect on host condition in dunas de mira, portugal. | the present study focuses on the helminth parasite community of the wild rabbit in a sand dune area in portugal over a 5-year period. the influence of host sex and year on the composition of the helminth community is assessed, along with the potential effect of the detected helminths on host body condition. the basic structure of the helminth community comprises mosgovoyia ctenoides, graphidium strigosum, trichostrongylus retortaeformis, nematodiroides zembrae and passalurus ambiguus. mean inten ... | 2007 | 17594739 |
| [embryonic development of the cestode mosgovoyia ctenoides (anoplocephalidae)]. | in this study the cleavage divisions and the ultrastructural analysis of early embryos as well as cellular organisation of infective oncosphere of the anoplocephalid cestode mosgovoyia ctenoides are described. the early cleavage is unequal and results in the formation of three types of blastomeres: 2 large macromeres containing large electron dense granules, 3 medium-size mesomeres and several small micromeres. in the early stage of oncospheral morphogenesis, formation of three following primary ... | 2007 | 17912814 |
