survey of hepatic and pulmonary helminths of wild cervids in alberta, canada. | during the 1988 hunting season, livers and lungs from 263 mule deer (odocoileus hemionus hemionus), 198 moose (alces alces), 147 white-tailed deer (odocoileus virginianus), and 94 wapiti (cervus elaphus nelsoni) from alberta (canada) were collected for parasitological examination. most of the samples (89%) were submitted by big game hunters throughout the province. giant liver fluke (fascioloides magna) was found in 9% of 22 yearling and 29% of 65 adult wapiti; 4% of 161 adult moose; and 2% of 9 ... | 1990 | 2250321 |
echinococcus granulosus (cestoda: taeniidae) infections in moose (alces alces) from southwestern quebec. | investigation of the distribution of larval echinococcus granulosus in a moose population from southwestern quebec revealed a distinct and stable pattern of infection with a prevalence of 44% (n = 580). positive correlations between moose age and the intensity, mean cyst weight and biomass of the hydatid cysts suggested a process of continued parasite acquisition and cyst growth. the distribution of cyst sizes within individual moose provided circumstantial evidence of interaction between cysts, ... | 1987 | 3625899 |
echinococcus granulosus in finland. | echinococcus granulosus is shown to occur in eastern finland in a sylvatic cycle involving wolves (canis lupus) as the definitive host and reindeer (rangifer tarandus tarandus) and probably also elk (alces alces) and the wild forest reindeer (rangifer tarandus fennicus) as intermediate hosts. even though the prevalence of e. granulosus in reindeer has increased in recent years, it is still very low (<0.013%). the results suggest, however, that the reindeer is a good sentinel animal to show the c ... | 2003 | 12531293 |
the significance of the artificial introduction of reindeer (rangifer tarandus) and moose (alces alces) in the spread of hydatid disease (echinococcus granulosus). | | 1964 | 14212887 |
the distribution of echinococcus granulosus in moose: evidence for parasite-induced vulnerability to predation by wolves? | the role of parasites in influencing the trophic dynamics of hosts is becoming increasingly recognized in the ecological literature. echinococcus granulosus is a tapeworm that relies on the predator-prey relationship between the definitive host (wolf, canis lupus) and the intermediate host, (moose, alces alces) to complete its life cycle. heavy infection by e. granulosus may predispose moose to increased risk of predation by wolves. theory predicts that parasite-induced vulnerability to predatio ... | 2004 | 15232731 |
first report of echinococcus granulosus g8 in eurasia and a reappraisal of the phylogenetic relationships of 'genotypes' g5-g10. | in this study, we investigated the presence of the larval stage of the tapeworm echinococcus granulosus in wild ungulates in estonia, genetically characterized e. granulosus isolates using mitochondrial gene sequences and used the sequence data, together with those available in a public database, to infer the phylogenic relationships of e. granulosus 'genotypes' g5-g10. while 0.8% of the 2038 moose (alces alces) examined were found to be infected with e. granulosus, the parasite was not detected ... | 2008 | 18261256 |
surveillance for echinococcus canadensis genotypes in canadian ungulates. | the geographic and host distribution, prevalence and genotypes of echinococcus canadensis in wild ungulates in canada are described to better understand the significance for wildlife and public health. we observed e. canadensis in 10.5% (11/105) of wild elk (wapiti; cervus canadensis) in riding mountain national park, manitoba, examined at necropsy, over two consecutive years (2010-2011). molecular characterization of hydatid cyst material from these elk, as well as three other intermediate wild ... | 2013 | 24533321 |
