Taenia Species

Eighteen (72%) of 25 wolves from the La Verendrye Provincial Game Reserve in southwestern Québec harboured helminth parasites. The four species recovered were Alaria marcianae (LaRue, 1917) (= A. americana Hall and Wigdor, 1918) (Digenea: Diplostomatidae); Echinococcus granulosus Batsch, 1786 and Taenia hydatigena Pallas, 1766 (Cestoda: Taeniidae); and Dioctophyma renale Goeze, 1782 (Nematoda: Dioctophymatoidea). Prevalence was 16, 60, 4, and 16%, respectively. Unidentified Taenia species were found in four (16%) of the wolves. Examination of wolf faeces for taeniid eggs yielded an overall prevalence of 16%. Results are discussed in relation to the food habits of these wolves.

Wolves from the Yukon and Northwest Territories harbored the following gastrointestinal helminths: Alaria americana (10 of 171), A. arisaemoides (2/171), Diphyllobothrium sp, (1/171). Mesocestoidcs kirbyi (3/171), Taenia hydatigena (54/111), T. krabbei (63/111), T. pisiformis (2/111), T. serialis (41/111), Echinococcus granulosus (24/171), Toxascaris leonina (83/171). Uncinaria stenocephala (11/171), Spirocerca arctica (1/171), and S. lupi (1/171). Larval Trichinella spiralis occurred in 72 of 153 diaphragms. A. arisaemoides, M. kirbyi, and S. arctica were found for the first time in Canis lupus, while S. lupi, S. arctica, and the prevalence of T. spiralis in wolves are reported for the first time in Canada.

AbstractIn a survey carried out during the period May 1995 to November 1996, in communities of various ethnic groups in northern Israel, 206 dogs were examined for Echinococcus granulosus and other intestinal helminth parasites by arecoline hydrobromide purges and the coproantigen-ELISA. The arecoline test was performed close to the owners' homes, using plastic sheets secured to the ground. From 56 dogs examined in the Muslim town of Tamra, six (10.7%) were found to be infected with E. granulosus. Four of them also had a mixed infection of Taenia hydatigena and Dipylidium caninum (two dogs), and the remaining two dogs were infected with either D. caninum or Taenia pisiformis. An additional 18 dogs were infected with either T. pisiformis (eight dogs), D. caninum (seven dogs), or T. hydatigena (three dogs). Two of these dogs harboured mixed infections whereas the remaining 32 dogs were free of helminths. In the Jewish villages, none of the 150 dogs examined were infected with E. granulosus, although 26 (17.3%) were infected with D. caninum, four (2.7%) with Ancylostoma spp. and one (0.7%) with Toxocara canis. Only one of the 22 stray dogs and none of the 15 jackals examined were infected with E. granulosus. However, 21 (95.4%) of the dogs and 12 (80%) of the jackals harboured helminth infections, including: D. caninum (16 dogs and seven jackals), Ancylostoma spp. (five jackals), T. hydatigena (three dogs), and T. canis (one dog). Approximately 18% of the dogs and 33% of the jackals showed mixed infections with two or more of the above helminths. In the abattoirs, 52 (5.9%) of the 874 sheep and 33 (5.3%) of the 616 goats from 17 herds slaughtered in the Muslim and Druze villages were found to be infected with E. granulosus, compared with a 0% infection rate observed in 93 sheep from two herds in Jewish villages.

Forty-three coyotes, 12 wolves, and 6 red foxes from an area around Riding Mountain National Park in southwestern Manitoba were examined for parasitic helminths. Eleven, 8, and 5 species were found in coyotes, wolves, and red foxes, respectively. Alaria marcianae, Alaria arisaemoides, and Toxascaris leonina were found in all three host species; Echinococcus granulosus, Taenia hydatigena, Uncinaria stenocephala, and Oslerus (Oslerus) osleri in wolves and coyotes; and Echinococcus multilocularis in coyotes and red foxes. Taenia pisiformis and T. leonina were the most prevalent species in coyotes; E. multilocularis and E. granulosus, the most numerous. Echinococcus granulosus was the most prevalent and numerous species in wolves. Alaria marcianae and T. leonina were found in all red foxes. The significance of the coyote as a major definitive host of E. multilocularis in southwestern Manitoba is discussed.

The Italian wolf population in human-modified landscapes has increased greatly in the last few decades. Anthropisation increases the risk of transmission of many zoonotic infections and in this context, control of taeniid cestode species needs to be addressed from a One Health perspective. Predator-prey interactions are at the root of taeniid cestode transmission, and the wolf plays a key role in the maintenance and transmission of taeniids. To date, all available data on the taeniids of wolves in Italy refer to populations living in a wild habitat. Between 2018 and 2019, we investigated taeniids in a wolf pack living in a highly anthropic hilly agro-ecosystem. Thirty-eight faecal samples were collected and analysed, 4 of which were also genetically characterised for individual wolves and belonged to three different animals. Samples collected were analysed microscopically and by molecular analysis in order to identify the taeniid species. Taeniid eggs were detected in 34.2% (13/38) of samples. Within samples positive to taeniid eggs only Echinococcus granulosus s.s. and Taenia hydatigena were identified in 26.3% and 10.5% of the samples, respectively. On microscopic examination, Capillaria spp., Ancylostomatidae and Toxocara canis eggs, Crenosoma vulpis larvae, and coccidian oocysts were also found. The combination of low biodiversity of taeniid species with a high occurrence of E. granulosus s.s. recorded in this study could be the consequence of a deeper link occurring between wolves and livestock in human-modified landscapes than in wild settings.

Diphyllobothrium Latum

Gray wolves (Canis lupus L., 1758) are mobile opportunistic predators that can be infected by a wide range of parasites, with many acquired via predator–prey relationships. Historically, many of these parasites were identified only to genus or family, but genetic tools now enable identification of parasite fauna to species and beyond. We examined 191 intestines from wolves harvested for other purposes from regions in the Northwest Territories, British Columbia, Saskatchewan, and Manitoba. Adult helminths were collected from intestinal contents for morphological and molecular identification, and for a subset of wolves, fecal samples were also analyzed to detect helminth eggs and protozoan (oo)cysts. Using both detection methods, we found that 83% of 191 intestines contained one or more parasite species, including cestodes (Taenia spp., Echinococcus spp., and Diphyllobothrium sp.), nematodes (Uncinaria stenocephala Railliet, 1884, Trichuris spp., Physaloptera spp., and Toxascaris leonina (von Linstow, 1902)), a trematode (Alaria sp.), and protozoa (Sarcocystis spp., Giardia sp., and Cryptosporidium spp.). Molecular characterization identified one species of Diphyllobothrium (Diphyllobothrium latum (L., 1758) Cobbold, 1858), three species of Taenia (Taenia krabbei Moniez, 1879, Taenia hydatigena Pallas, 1766, and Taenia multiceps Leske, 1786), and two Giardia duodenalis (Davaine) Deschiens, 1921 assemblages (B and C). These results demonstrate the diverse diet of wolves and illustrate the possibility of parasite spillover among wildlife, domestic animals, and people.
