“…For example, felids and canids are incidental hosts, meaning the juveniles can survive in the host but fail to reach sexual maturity (Karmanova, 1986). More specifically, S. baturini is most commonly found in sable (Martes zibellina (Linnaeus)), American marten (Martes americana (Turton)), and Pacific marten (Martes caurina (Merriam)) and less frequently in ermine (Mustela erminea Linnaeus), wolverine (Gulo gulo (Linnaeus)), and mink (Neovison vison (Schreber)) (Petrov, 1930;Price, 1930;Shimakura and Odajima, 1934;Bezdek, 1942;Morgan, 1943;Schmidt and Kinsella, 1965;Swartz, 1968;Kontrimavichus, 1985;Karmanova, 1986;Sato et al, 1999;Rusin et al, 2003;Zarnke et al, 2004).

Koehler, Anson V.A.; Hoberg, Eric P.; Dokuchaev, Nikolai E.; and Cook, Joseph A., "Geographic and Host Range of the Nematode Soboliphyme baturini across Beringia" (2007 Petrov, 1930, was found to represent a single species with a relatively broad geographic range across Beringia and northwestern North America on the basis of the assessment of molecular sequence data for adult and juvenile parasites. Refuted are hypotheses suggesting that several cryptic species could be partitioned either among an array of mustelid definitive hosts or across the vast region that links North America and Eurasia. Host specificity for this species is examined on the basis of a comprehensive list for definitive hosts, derived from new field surveys and existing literature for S. baturini. Only 5 mustelids (Gulo gulo, Martes americana, M. caurina, M. zibellina, and Neovison vison) appear to have significant roles in the life history, persistence, and transmission of this nematode. Soboliphyme baturini readily switches among M. americana, M. caurina, Mustela erminea, or N. vison at any particular locality throughout its geographic range in North America, although Martes spp. could represent the source for nematodes in a broader array of mustelids. Molecular analyses (243 base pairs of mitochondrial gene nicotinamide dehydrogenase [ND4]) suggest that hypotheses for host specificity across an array of mustelid definitive hosts are not supported. The life cycle of S. baturini is explored through a review of diet literature for 2 marten species, M. americana and M. caurina, and other mustelids across the Holarctic. Shrews (Soricomorpha: Soricidae) comprise Ͼ8% of prey for these species of Martes, suggesting their putative role as paratenic hosts. Juvenile nematodes found in the diaphragms of soricids are genetically identical to adult S. baturini found in the stomachs of mustelids at the same locations in both Asia and North America, corroborating a role in transmission for species of Sorex.Establishing the roles for each participant in a parasite's life cycle is essential to interpreting ecology, epidemiology, distribution, and phylogeographic history. Hosts that are components of the life cycle can be defined as definitive (parasite achieves sexual maturity), intermediate (parasite develops, but does not reach sexual maturity), and paratenic (parasite undergoes no development stages, but might be transported from one trophic level to another) (Roberts and Janovy, 2005). Hosts can also be defined as incidental, when the parasite fails to reach sexual maturity. In this case, the host is unnecessary to the parasite life cycle and, therefore, could be insignificant to a parasite's evolutionary past. On the other hand, definitive hosts can have long-term coevolutionary relationships with their parasites, or the host/parasite relationship could be acquired through host switching (e.g., Brooks and McLennan, 1993;. Recent relationships from host switching could be the result of ecological fitting (resource tracking), in which the parasite is ...

“…Our previous report [12] added several helminth species that had not been recorded from carnivores distributed in the north-western part of Tohoku region, Japan [15]. These are Taenia polyacantha from foxes (Vulpes vulpes japonica), Pygidiopsis summa from a raccoon dog (Nyctereutes procyonoides viverrrinus), Eucoleus aerophilus, Aonchotheca putorii, and Soboliphyme baturini from martens (Martes melampus melampus).…”

ABSTRACT. In the winter of 1998-1999, we collected parasitological data from 54 wild carnivores in the north-western part of Tohoku region, Japan. These consisted of 38 martens (Martes melampus melampus), 14 raccoon dogs (Nyctereutes procyonoides viverrinus) and 2 foxes (Vulpes vulpes japonica). Collected helminth parasites were 11 nematode, 10 trematode, 3 cestode, and a single acanthocephalan species, including 5 hitherto unknown species for this research area or the mainland of Japan (Honshu). Mesocestoides paucitesticulus was for the first time recorded from martens as well as from carnivores distributed in Honshu. Brachylaima tokudai originally recorded from Urotrichus talpoides in the central part of Honshu was for the first time found from a raccoon dog.-KEY WORDS: helminth, Martes melampus, Nyctereutes procyonoides.

“…Since Nagayosi (1955) first identified A. miyazakiense from the intestines of raccoon dogs captured in Japan, the parasite has been reported only in wild animals in Japan (Sato et al, 1999a(Sato et al, , 1999b(Sato et al, , 2006). It appears that the parasite is particularly common in Aomori and Akita Prefectures, Japan, as 18 of 20 raccoon dogs caught in these areas were infected with the parasite.…”

“…Its broad geographical distribution and omnivorous nature expose the animal to a broad spectrum of pathogens and parasites (Woon, 1967). Consequently, numerous parasites of raccoon dogs have been identified elsewhere (Sato et al, 1999b). Raccoon dogs are also known to be carriers of rabies, canine distemper, encephalitis, coccidiosis, toxoplasmosis, tuberculosis, leptospirosis, roundworms, and mange mites.…”
