“…Hydatid cysts of E. multilocularis were reported in A. argenteus in Hokkaido [22]. However, the cysts were not detected in the present study as well as in the previous studies carried out in the Honshu district [4,6,12]. On the other hand, there are few reports on protozoan parasites from wild rodents [2,17].…”

“…Tania polyacantha, infecting red foxes, was previously reported from Finland, Norway, Denmark, Wales, Germany, France, Switzerland, Austria, Poland, Bulgaria, Italy, Yugoslavia and Japan [32,33]. In this study, 13 adult tapeworms of "Taenia polyacantha-like" were found for the rst time in three red foxes (#5, #6 and #8) in China.…”

Background The red fox (Vulpes vulpes) is a geographically widespread predator species, occurring across the northern Hemisphere. It has high veterinary-medical significance, in part owing to its definitive host role in the life cycle of several tapeworm species, including zoonotic ones. However, there have been only few reports on cyclophyllid tapeworm (Cestoda: Cyclophyllidea) infection in red foxes from China. Methods In this study, 263 tapeworms were collected from eight road-killed red foxes in Xinjiang Uygur Autonomous Region (XUAR, northwestern China). The tapeworms were analyzed based on morphological characters and mitochondrial cytochrome c oxidase subunit 1 (cox1) gene sequences. Results 83 Taenia and 180 Mesocestoides tapeworms were identified according to the presence or absence of rostellum, and the number, the length and the shape of the large rostellar hooks. The morphological and molecular analyses revealed that i) 180 Mesocestoides tapeworms, here named as Mesocestoides sp. Vulpes vulpes, showed 99.21% (378/381 bp) identity to Mesocestoides sp. reported from red fox in Mongolia; and ii) 83 Taenia tapeworms belonged to three species. The first Taenia species (n = 16, named as Taenia sp. Vulpes vulpes), based on the length of large rostellar hooks (337–342 µm) and its cox1 sequence, was identified as a potentially novel species, which is phylogenetically close to Taenia laticollis. The second species (n = 54, named as Taenia sp. Vulpes vulpes & Rhombomys opimus), was morphologically similar to Taenia endothoracicus according to the number (n = 52), the length (319–332 µm) and the shape of the large rostellar hooks. This species, infecting three red foxes, shared 100% cox1 sequence identity with Taenia sp. Rhombomys opimus genotype C found previously in great gerbils (Rhombomys opimus) in the same region. The third species (n = 13, named as Taenia polyacantha-like), had shorter large rostellar hooks (178–180 µm) and showed 96.27% (361/375 bp) sequence identity to Taenia polyacantha reported from red fox in Italy. In addition, co-infections with two Taenia species and with Taenia and Mesocestoides species were also demonstrated. Conclusions The “great gerbil-red fox” life cycle of Taenia sp. Vulpes vulpes & Rhombomys opimus, belonging to the mitochondrial lineage of T. endothoracicus, is confirmed. The T. polyacantha-like species and Mesocestoides sp. Vulpes vulpes were found for the first time in red fox in China. Taenia sp. Vulpes vulpes is a potentially novel species, which is close to Taenia laticollis based on its phylogenetic properties. The life cycle of Taenia sp. Vulpes vulpes and Mesocestoides sp. Vulpes vulpes should be further explored.

“…Unlike the Echinococcus species, information about the Taenia infection in Tibetan foxes is limited. Taenia polyacantha has a wide distribution from the northern part of the Eurasia continent, from the UK to Japan ( Ihama et al, 2000 ). Several canid species have been confirmed as definitive hosts including the red fox ( Vulpes vulpes ) ( Al-Sabi et al, 2014 ; Lavikainen, 2008 ), the arctic fox ( Vulpes lagopus ) ( Stien et al, 2010 ), the gray wolf ( Canis lupus ) ( Ćirović et al, 2015 ), the raccoon dog ( Nyctereutes procyonoides ) ( Thiess et al, 2001 ), and the domestic dog ( C. familiaris ) ( Umhang et al, 2014 ).…”

Tibetan foxes ( Vulpes ferrilata ) have been confirmed as the main wild definitive hosts in echinococcosis transmission in the eastern Tibetan Plateau. However, little information is available about the epidemiology in wildlife from the perspective of the Taeniidae family, which is essential knowledge in understanding the epidemiology and phylogeography of cestode species in the Tibetan plateau. Therefore, in this study, we used copro-PCR techniques, by amplifying nad1 and cox1 gene fragments, to detect the taeniid species from Tibetan fox feces collected in Shiqu County, (Sichuan Province, China), eastern Tibetan Plateau. Phylogenetic relationships between amplified sequences and existed Taenia species genotypes were evaluated. Then, the maximum prevalence (positive PCR results from at least one primer pair) and the conservative prevalence (positive PCR results from at least two primer pairs) were calculated. Thirty-six Tibetan fox feces were analyzed. Echinococcus multilocularis (conservative prevalence ± 95% CI: 22.2% ± 13.6%; maximum prevalence ± 95% CI: 33.3% ± 15.4%) and E. shiquicus (2.8 ± 5.4%; 8.3 ± 9.0%) was detected. Meanwhile, DNA fragments of T. polyacantha were detected with high similarity to NCBI sequences ( cox1 , 94.0%) and to the larva sample DNA sequenced in this study (93.4%), and were supported by phylogenetic analysis. Thus, T. polyacantha might infect Tibetan foxes (5.6% ± 7.5%, 11.1% ± 10.3%). Our limited findings in the epidemiology of parasitic Taenia species suggest that sylvatic transmission cycles for a more species-rich Taeniid community must be established between wild canids and small mammals than just for the two Echinococcus species. Besides, discrepancies in different primer pairs in detecting the taeniid species were evaluated. The sensitivity of some widely used universal primer pairs was poor in detecting Taenia species from canid copro-DNA samples. It is still challenging to the development of effective taeniid species-specific molecular markers especially for non-zoonotic species.
