| morphology of the oviduct fluke, prosthogonimus ovatus, isolated from indonesian native chickens and histopathological observation of the infected chickens. | prosthogonimus ovatus infection was detected in 5 of 130 chickens in the oviduct and 4 chickens in the bursa of fabricius. scanning electron microscopy (sem) revealed that the spines of the p. ovatus were densely distributed on the cuticula of the entire dorsal surface of body, but on the ventral surface, they were densely present to the level of ventral sucker but gradually decreased in density posteriorly, and they could not be seen in the posterior 1/3 area. the spines were finger-shaped and ... | 2002 | 12520106 |
| [distribution of trematodes of the family prosthogonimidae in river and lake ecological systems in the south of the western siberia]. | the results of long-term investigations (1994-2003) of an infection rate of trematodes of the family prosthogonimidae in the first intermediate hosts (snails of the family bithyniidae) and in the final hosts (birds) from a basin of the chany lake (western siberia) are discussed. a total of 1824 specimens of bithynia tentaculata (l., 1758) and 7166 specimens of opisthorchophorus troscheli (paasch, 1842) have been collected from eight rivers and two lakes in the south of the western siberia. data ... | 2005 | 15810558 |
| [taxonomic, topical and quantitative structure of the community of intestinal flukes (digenea) of mallards, anas platyrhynchos linnaeus, 1758 from the area of szczecin]. | taxonomic, topical and quantitative structure of the community of intestinal flukes (digenea) of mallards, anas platyrhynchos linnaeus, 1758 from the area of szczecin. a total of 55 mallards (anas platyrhynchos l.) from the area of szczecin were examined for the presence of intestinal flukes (digenea). this study covered the taxonomic structure (specific composition and taxonomic affiliation of the parasites), topical structure (parasites' distribution within the host's organism), and quantitati ... | 2002 | 16894718 |
| [enteric helminths of the mallard anas platyrhynchos l., 1758 in the north-western part of poland]. | although the mallard, anas platyrhynchos, is the most common wild duck in poland, as well as in the entire palearctic, it is extremely rarely studied by comprehensive parasitological surveys. the aim of this study was to present a synthesis on the species composition of enteric helminths of the mallard in north-western poland. the study was carried out in 1999-2006 and involved parasitic worms isolated from the alimentary tracts of 187 mallards (anseriformes: anatidae). following isolation, the ... | 2008 | 18664102 |
| taxonomic structure of digenea in wild ducks (anatinae) from west pomerania. | parasitic fauna of birds connected with water environment, including digeneans, is relatively well researched in poland. the exception, however, is west pomerania, where those birds were not frequent objects of parasitological research until recently. the purpose of this work is to determine the taxonomic structure of the digenea, parasitising wild ducks living in west pomerania. the research material was 124 individuals of wild anatinae (anseriformes) belonging to 8 species: anas strepera, a. c ... | 2008 | 18702318 |
| the helminth fauna of the red-crested cardinal (paroaria coronata) passeriformes: emberizidae in brazil. | with the objective of identifying the helminths of paroaria coronata, 40 birds were necropsied, and their organs and contents were examined. the parasites were preserved in 70 masculinegl alcohol and prepared for identification using standard techniques. the helminth fauna found in p. coronata were aproctella carinii, dispharynx nasuta, capillaria sp., diplotriaena sp., tanaisia oviaspera, tanaisia valida, tanaisia sp., prosthogonimus ovatus, orthoskrjabinia sp., and mediorhynchus sp., with nema ... | 2009 | 19636590 |
| helminth parasitism in the neotropical cormorant, phalacrocorax brasilianus, in southern brazil: effect of host size, weight, sex, and maturity state. | forty-seven specimens of neotropical cormorants, phalacrocorax brasilianus, from lago guaíba, guaíba, state of rio grande do sul, brazil (30° 00' s, 51°15' w), were examined for helminth parasites between 1999 and 2003. twenty species of helminth parasites were found: ten digeneans: austrodiplostomum mordax, austrodiplostomum compactum, clinostomum sp., drepanocephalus olivaceus, drepanocephalus spathans, hysteromorpha triloba, ignavia olivacei, paryphostomum segregatum, prosthogonimus ovatus, a ... | 2011 | 21431903 |
| the neuro-muscular system in continuously swimming cercariae from belarus. i xiphidiocercariae. | the neuromuscular system (nms) in cercariae of neoastiotrema trituri, plagiorchis elegans, omphalometra flexuosa, skrjabinoeces similis and prosthogonimus ovatus was studied with immunocytochemical methods and confocal scanning laser microscopy. the patterns of f-actin in the musculature, 5-ht immunoreactive (ir), fmrfamide-ir neuronal elements and α-tubulin-ir sensory receptors were investigated, and they were found to be rather similar in all the cercariae studied. four species have seven pair ... | 2012 | 22868890 |
| integrative taxonomy of central european parasitic flatworms of the family prosthogonimidae lühe, 1909 (trematoda: plagiorchiida). | species of the family prosthogonimidae are considered the most pathogenic poultry trematodes worldwide, affecting particularly low intensity farming in rural areas. adults of prosthogonimus occur mainly in the bursa of fabricius, oviduct and cloaca of ducks, geese, fowl and other birds feeding at least occasionally on dragonflies or damselflies (odonata). we analyzed the central european species of the prosthogonimidae, namely prosthogonimus cuneatus, prosthogonimus ovatus, prosthogonimus pelluc ... | 2015 | 25724855 |
| helminths of molothrus bonariensis (gmelin, 1789) (passeriformes: icteridae) from southernmost brazil. | information about helminths of molothrus bonariensis (gmelin, 1789) (passeriformes: icteridae) are scarce; in this sense the objective of this paper was to contribute to its knowledge. five hosts of southern brazil were examined and the helminths prosthogonimus ovatus, tanaisia valida (digenea), diplotriaena bargusinica and synhimantus (dispharynx) nasuta (nematoda) were identified. the species t. valida, p. ovatus and s.
