Morphology, homogonic development, and lack of a free-living generation in Strongyloides robustus (Nematoda, Rhabditoidea), a parasite of North American sciurids



Morphology, homogonic development, and lack of a free-living generation in Strongyloides robustus (Nematoda, Rhabditoidea), a parasite of North American sciurids



Folia Parasitologica 42(2): 102-114



Adult females of Strongyloides robustus, a parasite of sciurids in North America, were found in the duodenal mucosa of 30 of 32 red squirrels (Tamiasciurus hudsonicus) collected in Cape Breton Island, Nova Scotia, Canada. The parasitic female is figured and redescribed; characteristics include: body 3.8-8.0 mm long, cephalic extremity with X-shaped mouth and 8 circumoral lobes, ovaries spiralling around intestine, and tail bluntly rounded. Eggs in fresh faeces contained tadpole-stage larvae.
