Three species of trematode [Orchipedium jolliei Schell, 1967; Prohyptiamus grusi Kocan, Waldrup, Ramakka, and Iverson, 1982; Echinostoma revolutum (Froelich, 1802)], three species of nematode (Tetrameres grusi Shumakovich, 1946; Synhimanthus sp.; Contracaecum sp.), and one species of cestode (Anomotaenia sp.) were recovered from 146 sandhill cranes, Grus canadensis (Linnaeus), collected in Alaska, Canada, and two areas in Texas. The only common and abundant species were O. jolliei and T grusi. Of cranes collected in Texas, those that came from the Canadian breeding grounds had significantly greater abundances of O. jolliei and T. grusi than those from Alaska. However, cluster analysis using rank abundances of helminth species across the four geographic regions and stepwise multiple discriminant analysis using the grouping variable of the presence or absence of a subspecies-specific pancreatic protein indicated that classification of cranes into populations based on helminth abundances was impractical as a management technique.  相似文献

The helminth fauna of the genus Talpa in the Palaearctic Realm is reviewed. Several helminth species reported in Talpa spp. by a number of authors are discussed, with reference to host specificity, parasite biology, and host ethology, ecology and phylogeny. Twelve species of cestodes were found, two of which exhibit stenoxenous specificity (Staphylocystis bacillaris and Multitesticulata filamentosa). Only three species of trematodes, Ityogonimus lorum, Ityogonimus ocreatus and Combesia macrobursata, are exclusive parasites of Talpa spp. The largest group are nematodes, with 37 species. Species of Tricholinstowia are parasites of holarctic talpids and several species of distinct genera, such as Capillaria, Soboliphyme and Trichuris, are found only in Talpa spp. Only acanthocephalans of the genus Moniliformis have been reported in moles of the genus Talpa. On the basis of these helminthological findings, the close phylogenetic relationship between moles (Talpidae) and shrews (Soricidae) supports the separation of the ordinal levels Soricomorpha and Erinaceomorpha.  相似文献

Thirty-seven carcasses of Eurasian lynx (Lynx lynx) collected and examined in Estonia during 1999-2001 had helminths. Parasites identified and their prevalence included Diphyllobothrium latum (5%), Taenia pisiformis (100%), Taenia laticollis (41%), Taenia hydatigena (3%), Taenia taeniaeformis (3%), Toxocara cati (68%), and Trichinella spp. (22%). The only significant relationships (P < or = 0.05) between occurrence of helminths and host age and sex were a greater number of T. pisiformis and T. laticollis in older than in youger male lynx, and older males had a greater number of species of helminth than did younger lynx. Sixty-one fecal samples collected during snow tracking of nine lynx were examined; eggs of T. cati were identified in 38 samples, and Capillaria spp were found in eight samples. This is the first systematic investigation of parasites of lynx in Estonia.  相似文献

The gastrointestinal tracts of 32 free-ranging, 9-banded armadillos (Dasypus novemcinctus) from north-central Florida were examined for the presence of helminths during July 1991 to November 1993. Aspidodera sp. (Nematoda: Aspidoderidae), most closely resembling Aspidodera sogandaresi, were recovered from 20 of 32 armadillos examined. Total numbers of A. sogandaresi ranged from 1 to 1,021 per infected animal, and followed an inverse correlation to body condition index for those animals. The cystacanth stage of 1 acanthocephalan, Macracanthorhynchus ingens, was present in 1 armadillo, and is the first report of M. ingens in the 9-banded armadillo. The present study contributes to the known natural history of the 9-banded armadillo, an important animal research model.  相似文献

Thirty-six helminth species were found in 324 gulls examined during June 1994 to February 1996 from different localities of Galicia: 25 trematodes (Brachylaima sp., Brachylecithum microtesticulatum, Cardiocephaloides longicollis, Cryptocotyle lingua, Cryptocotyle concavum, Diplostomum spathaceum, Echinostephilla virgula, Galactosomum phalacrocoracis, Gigantobilharzia acotylea, Gymnophallus deliciosus, Gynaecotyla longiintestinata, Himasthla elongata, Himasthla quissetensis, Knipowitschiatrema nicolai, Levinseniella (Levinseniella) propinqua, Maritrema gratiosum, Maritrema linguilla, Microphallus primas, Microphallus similis, Ornithobilharzia canaliculata, Parorchis acanthus, Phagicola minuta, Psilostomum brevicolle, Renicola sp. and Stephanoprora denticulata), four cestodes (Alcataenia micracantha, Microsomacanthus ductilis, Tetrabothrius (Oriana) erostris and Wardium cirrosa), six nematodes (Anisakis simplex, Contracaecum rudolphii, Cosmocephalus obvelatus), Eucoleus contortus, Paracuaria adunca and Tetrameres (Tetrameres) skrjabini) and one acanthocephalan (Arhythmorhynchus longicollis). Tetrabothrius erostris was the most prevalent species (79.6%), followed by C. obvelatus (47.8%), C. lingua (37.4%), G deliciosus (30.9%), G. longiintestinata (22.8%), P. adunca (21.9%), B. microtesticulatum (17.6%), E. contortus (14.5%) and M. similis (9.3%). Microphallus similis was the dominant species, with a Berger-Parker index (BP) of 0.32, followed by T. erostris (BP=0.10). All species presented an aggregated dispersion except G. acotylea and G. phalacrocoracis, which showed a random dispersion. Species that seem to have the greatest predilection for specific sites along the intestine are: C. longicollis and A. micracantha (first third), Brachylaima sp., M. similis and G. longiintestinata (last third) and A. longicollis (second half). Eight species are known to be pathogenic to commercially important fish or molluscan species and several are pathogenic to humans.  相似文献

Helminth fauna of Insectivora was investigated in canal banks situated in meliorated territories of Belorussian Polesie during 1996-1999. Thirty-three helminth species were found in the animals examined. Most of the parasites are usual in common shrew Sorex araneus L., which is a predominate insectivore species in canal banks.  相似文献

The results of our own long-term helminthological investigations (1980-2010) of wolves in Belorussian Polesie are presented. 87.2% of wolves were infected by helminths according to helminthological autopsy, and 98.5% by coproscopical data. 26 species of helminths were found: 5 trematode species, 9 cestode species, 11 nematode species and 1 acanthocephalan species. The wolf is a new host for nematode Dirofilaria immitis (Leidy, 1856) in Belarus.  相似文献

A helminth fauna of small rodents inhabiting channel banks have been investigated in soil improvement territories (Belorussian Polesie) in the period 1996-1999. 41 helminth species have been found in animals. Generally, there are specific helminths of rodents of the Cricetidae and Muridae families. These animals also participate in life cycles of bird's and carnivore's helminths.  相似文献
