“…Fortunately, we recently collected a few specimens of S. planiceps from a raccoon dog in this region (Wakayama Pref.). Our specimens collected from raccoon dogs on Yakushima Island and in Wakayama Prefecture corresponded well in morphology, although our specimens showed shorter tail lengths than those provided by Horie et al [15][16][17][18] or the original description of this species by Rogers [34]. As mentioned above, this threadworm has been recorded sometimes in companion animals such as cats and dogs [8,[15][16][17].…”

ABSTRACT. Nematodes were collected from 14 raccoon dogs (Nyctereutes procyonoides viverrinus) on Yakushima Island, Kagoshima Prefecture (Kyushu), Japan, that were the progeny of recently introduced animals to this World Natural Heritage Area, probably within the last 2 decades. Seven nematode species (Toxocara tanuki, Ancylostoma kusimaense, Arthrostoma miyazakiense, Strongyloides planiceps, Trichuris vulpis, Gongylonema sp., and Dirofilaria immitis) were collected from the raccoon dogs. Two nematode species (Molineus legerae and Strongyloides martis) were collected from 2 Japanese weasels (Mustela itatsi) indigenous to this island that were killed by traffic accidents. Considering that foxes and other carnivores, except for weasels, dogs and cats, are not distributed on this island, most of soil-borne nematodes such as roundworms, hookworms, and threadworms in raccoon dogs should have been introduced by the original population from the mainland Japan, and the infection hence maintained at a high level by new generations. Recovery of the third-stage larvae of Gongylonema sp. from the esophagus of raccoon dogs was remarkably frequent (79%), suggesting that the animals might vigorously take insect hosts. Although S. martis have never been recorded from weasels in Japan until this study, this threadworm might be prevalent in a variety of mustelids in Eurasia.

A taxonomic study of Strongyloides Grassi, 1879 (Nematoda) with special reference to Strongyloides fuelleborni von linstow, 1905 in man in Papua New Guinea and the description of a new subspecies

The taxonomic position of a Strongyloides species parasitic in man in Papua New Guinea (PNG) that apparently resembled S. fuelleborni (a parasite of man and other primates in tropical Africa) has not been resolved since its discovery in 1973. The results of a morphological (by scanning electron microscopy) and morphometric study were considered together with the results of a separate isoenzyme electrophoretic study of the same material. The nature of the peri-vulval cuticle of the parasitic female and the position of the phasmidial pore of the free-living male were found to be of particular use in addressing this taxonomic problem. We concluded that the Strongyloides in Africa and PNG are subspecies of S. fuelleborni. We propose the name S. fuelleborni kelIyi n. subsp, for the Strongyloides found in man in PNG.

The stomal morphology of parasitic females of Strongyloides spp. by scanning electron microscopy

et al. 2007

View full text Add to dashboard Cite

For the discrimination of the species of the genus Strongyloides, the shape of the stoma in the apical view of parasitic females is the most important feature. Microscopical interpretations divided the shape of the stoma into four groups (simple, angular, complex, and simple but with esophageal teeth); however, the stomas classified in the latter two groups, in particular, remained unclear. In the present study, parasitic females of eight representative Strongyloides spp. with the angular stoma (S. procyonis and S. martis), complex stoma (S. robustus, S. callosciureus, S. planiceps, S. papillosus and S. myopotami), and stoma with esophageal teeth (S. ransomi) were studied by scanning electron microscopy. All species examined in this study having complex stoma or with esophageal teeth possessed at least four linguiform or verruciform projections submarginally in the stomal cavity. Namely, the number, size, shape, and the site of attachment of intra-stomal projections, along with the depth of oral cavity, determine a range of complex images of the stoma such as X-shaped or ornate stomas under light microscopy. Similarly, with the standard examination, which usually uses a lateral view of the head, erroneous interpretations of the number of lobes on the circumoral elevation of parasitic females might occur due to such intra-stomal projections in some Strongyloides spp.
