taenia arctos n. sp. (cestoda: cyclophyllidea: taeniidae) from its definitive (brown bear ursus arctos linnaeus) and intermediate (moose/elk alces spp.) hosts.taenia arctos n. sp. (cestoda: cyclophyllidea: taeniidae) is described from the brown bear ursus arctos linnaeus (definitive host) and moose/elk alces spp. (intermediate hosts) from finland (type-locality) and alaska, usa. the independent status of the new species and the conspecificity of its adults and metacestodes have been recently confirmed by the mtdna sequence data of lavikainen et al. (2011; parasitology international, 60, 289-295). special reference is given to morphological differences ...201122002024
phylogenetic characterisation of taenia tapeworms in spotted hyenas and reconsideration of the "out of africa" hypothesis of taenia in humans.the african origin of hominins suggests that taenia spp. in african carnivores are evolutionarily related to the human-infecting tapeworms taenia solium, taenia saginata and taenia asiatica. nevertheless, the hypothesis has not been verified through molecular phylogenetics of taenia. this study aimed to perform phylogenetic comparisons between taenia spp. from african hyenas and the congeneric human parasites. during 2010-2013, 233 adult specimens of taenia spp. were collected from 11 spotted hy ...201424815426
molecular identification of species of taenia causing bovine cysticercosis in ethiopia.bovine cysticercosis causing damage to the beef industry is closely linked to human taeniasis due to taenia saginata. in african countries, taenia spp. from wildlife are also involved as possible sources of infections in livestock. to identify the aetiological agents of bovine cysticercosis in ethiopia, cysticerci were collected from 41 cattle slaughtered in the eastern and central areas during 2010-2012. a single cysticercus per animal was subjected to the polymerase chain reaction (pcr)-based ...201423452760
first report of taenia arctos (cestoda: taeniidae) from grizzly (ursus arctos horribilis) and black bears (ursus americanus) in north america.the cestode taenia arctos was found at necropsy in the small intestine of a grizzly (ursus arctos horribilis) and a black bear (ursus americanus) from kananaskis country in southwestern alberta, canada. the autolysis of the tapeworm specimens precluded detailed morphological characterization of the parasites but molecular analysis based on mitochondrial dna cytochrome c oxidase subunit 1 gene confirmed their identity as t. arctos. this is the first report of t. arctos from definitive hosts in no ...201424382413
