comparative studies on the biology and morphology of echinococcus granulosus from domestic livestock, moose and reindeer.		1963	14080000
the significance of the artificial introduction of reindeer (rangifer tarandus) and moose (alces alces) in the spread of hydatid disease (echinococcus granulosus).		1964	14212887
echinococcus strains in europe: a review.	in european countries the following final/intermediate host assemblages of echinococcus granulosus are known to occur: (a) dog/sheep; (b) dog/horse; (c) dog/cattle; (d) dog/pig, (e) dog/reindeer (= "northern form" of e. granulosus). the parasites involved in cycles a-d have been identified as distinct strains in various countries. epidemiological aspects relevant to intraspecific variations and strain characteristics are described. in e. multilocularis there are some indications for intraspecifi ...	1988	3291073
the epidemiology of echinococcus granulosus in great britain. v. the status of subspecies of echinococcus granulosus in great britain.	twenty-five years ago williams and sweatman suggested that in great britain there are two subspecies of echinococcus granulosus--e. granulosus granulosus and e. granulosus equinus. echinococcus granulosus granulosus does not mature either in foxes or in horses: e. granulosus equinus will mature in either. the prepatent period of e. granulosus granulosus in the definitive host is about 42 days while that of e. granulosus equinus is about 70 days. each subspecies has a characteristic morphology. m ...	1989	2596902
[the spread of the principal socially important parasitic disease on the territory of the chukot autonomous okrug (chao)].	the paper provides the examination findings of helminthiases in the population of the town of anadyr, the settlements of kanchalan, krasneno, and in the reindeer-breeding teams of the anadyr district, cad. the children infected with enterobiasis were shown to amount to 15.1 to 22.9%, diphyllobothriasis was detected in 12.9 - 33.7% of the examinees. single cases of ascariasis were revealed. analysis of 232 cases with echinococcosis demonstrates that the infection is prevalent over the whole chuko ...	1996	8700016
hydatidosis: dynamics of transmission.	hydatidosis is a widespread zoonosis infecting a large number of animals and humans. echinococcus granulosus has the smallest taenia adult of the cestodes but with the largest larva. its morphologic and biologic features were identified with dna analysis. different strains were separated according to the intermediate hosts: sheep, cattle, pigs, horses, camels. definitive host are canids, mostly dogs, where the worm grows to adulthood in several months. the eggs are scattered in the pasture by wi ...	2001	11213154
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
molecular genetic characterization of the fennoscandian cervid strain, a new genotypic group (g10) of echinococcus granulosus.	the northern biotype of echinococcus granulosus occurs in north america and northern eurasia in life-cycles involving cervids. previously, cervid isolates of e. granulosus from north america have been characterized using molecular genetic techniques as the g8 genotype. in this study, 5 isolates of e. granulosus were collected from 4 reindeer and 1 moose in north-eastern finland. dna sequences within regions of mitochondrial cytochrome c oxidase i (coi) and nadh dehydrogenase i (ni)i) genes and t ...	2003	12964823
cystic echinococcosis in the arctic and sub-arctic.	the northern biotype of echinococcus granulosus occurs throughout the holarctic zones of tundra and taiga, from eastern fennoscandia to the bering strait in eurasia and in north america from arctic alaska approximately to the northern border of the united states. the cycle of the cestode is complex in taiga at lower latitudes, because of the greater diversity of potential hosts. in the arctic and subarctic, however, four patterns of predator/prey relationships may be discerned. two natural cycle ...	2003	15027606
helminthologic survey of the wolf (canis lupus) in estonia, with an emphasis on echinococcus granulosus.	carcasses of 26 wolves were collected during the 2000/2001 and 2003/2004 hunting seasons and examined for helminths. thirteen helminth species were recorded: one trematode (alaria alata), seven cestodes (diphyllobothrium latum, mesocestoides lineatus, taenia hydatigena, taenia multiceps, taenia ovis, taenia pisiformis, and echinococcus granulosus), and five nematode species (uncinaria stenocephala, toxascaris leonina, toxocara canis, trichinella nativa, and trichinella britovi). the most common ...	2006	16870858
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
echinococcus canadensis transmission in the north.	the echinococcus granulosus complex (eg) is the causative agent of cystic echinococcosis (ce). northern cervid echinococcus was previously suggested to be the ancestor of the entire eg. during the last century, it was regarded to have three (or four) different, but often overlapping, transmission cycles in the circumpolar north: the original wolf-wild cervid (reindeer or elk)-cycle; the semi-synanthropic cycle involving sled and hunting dogs and wild cervids; and the synanthropic cycle involving ...	2015	26264249
