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 lympha...
