| lymphatic dwelling filarioid nematodes in reindeer rangifer tarandus tarandus, (cervidae) in finland, identified as rumenfilaria andersoni lankester & snider, 1982 (nematoda: onchocercidae: splendidofilariinae). | a filarioid nematode inhabiting the lymphatic vessels of the subserosal rumen and mesenteries associated with a high prevalence of its microfilariae in peripheral blood was observed in finnish reindeer (rangifer tarandus tarandus) in 2004 and 2006. adult specimens were collected by dissecting lymphatic vessels from slaughtered animals, where some of the nematodes were seen through the wall of the dilated vessels as thin white winding threads obscuring the vessel. the morphology of adult worms an ... | 2010 | 20387735 |
| a lymphatic dwelling filarioid nematode, rumenfilaria andersoni (filarioidea; splendidofilariinae), is an emerging parasite in finnish cervids. | recent studies revealed expansion of filarioid nematodes into northern finland. in addition to setaria tundra, an abundant filarioid, rumenfilaria andersoni, was found inhabiting the lymphatic vessels of reindeer. our study explores the dynamics of the rapid geographic expansion of r. andersoni, defining prevalence and density of microfilariae among 4 new cervid host species in finland while developing a context for host-parasite ecology in fennoscandia and more broadly in the arctic and boreal ... | 2015 | 25884201 |
| a new type f wolbachia from splendidofilariinae (onchocercidae) supports the recent emergence of this supergroup. | wolbachia are vertically transmitted endosymbiotic bacteria of arthropods and onchocercid nematodes. it is commonly accepted that they co-evolved with their filarial hosts, and have secondarily been lost in some species. however, most of the data on the wolbachia/onchocercidae relationship have been derived from studies on two subfamilies, the dirofilariinae and the onchocercinae, which harbour parasites of humans and domestic animals. within the last few years, analyses of more diverse material ... | 2012 | 23041355 |
| molecular and phylogenetic analysis of the filarial nematode micipsella numidica from the hare lepus europaeus in italy. | the genus micipsella comprises three species of filariae to date identified in lagomorphs only, whereas the other genera belonging to the subfamily splendidofilariinae are described as parasites of birds, reptiles and mammals. in the present study seven specimens of micipsella numidica (seurat, 1917), collected from the hare lepus europaeus in italy, were characterized genetically by molecular amplification of the mitochondrial genes (12s rdna; cox1) and the 5s rdna gene spacer region. phylogene ... | 2016 | 26123728 |
| epidemiology of the lymphatic-dwelling filarioid nematode rumenfilaria andersoni in free-ranging moose (alces alces) and other cervids of north america. | moose (alces alces) are a culturally and economically valued species in minnesota, where the northeast population has decreased by 60 % since 2006. the cause of the decline is currently unclear; however, parasites, predation, and climate change have all been implicated. nematode parasites are important pathogens in north american moose, potentially causing severe disease and mortality. recent spread of rumenfilaria andersoni, a filarioid nematode of moose, has been documented in finnish cervids; ... | 2016 | 27519789 |
