First report of Taenia laticollis and a new species, “Taenia sp. Eurasian lynx” from the Eurasian lynx (Lynx lynx) in Northwestern China

Abstract BackgroundThe Eurasian lynx (Lynx lynx) is a medium-sized wild cat species distributed throughout Eurasia, from Europe to the Far East. There has been no report on Taenia species (Cestoda: Cyclophyllidea) infecting this felid in China.MethodsIn this study, 24 tapeworms were found in two Eurasian lynxes (#1 and #2) in Xinjiang, northwestern China. The tapeworms were identified based on two mitochondrial genetic markers, the cytochrome c oxidase subunit 1 (cox1) and 16S rDNA. This was followed by detailed morphologic characterization.ResultsMolecular and phylogenetic analyses of the cox1 gene revealed that i) a single tapeworm from lynx #2 shared 100% identity with Taenia laticollis genotype C detected in Eurasian lynx in Finland, and ii) the remaining 23 tapeworms, provisionally named here as “Taenia sp. Eurasian lynx”, had two nucleotide substitutions but phylogenetically clustered together. The latter showed only 93.25% sequence identity to T. hydatigena from sheep (Ovis aries) in Slovakia. The scolex morphology is characteristic enough to distinguish “Taenia sp. Eurasian lynx” from other species of its genus.Conclusions“Taenia sp. Eurasian lynx” is a novel tapeworm species found in Eurasian lynx. In addition, T. laticollis was found in this wild felid for the first time in China. The intermediate hosts of T. laticollis and “Taenia sp. Eurasian lynx” should be explored in the near future.

SUMMARYCestodes of the genus Taenia are parasites of mammals, with mainly carnivores as definitive and herbivores as intermediate hosts. Various medium-sized cats, Lynx spp., are involved in the life cycles of several species of Taenia. The aim of the present study was to identify Taenia tapeworms in the Eurasian lynx (Lynx lynx) from Finland. In total, 135 tapeworms from 72 lynx were subjected to molecular identification based on sequences of 2 mtDNA regions, the cytochrome c oxidase subunit 1 and the NADH dehydrogenase subunit 1 genes. Available morphological characters of the rostellar hooks and strobila were compared. Two species of Taenia were found: T. laticollis (127 samples) and an unknown Taenia sp. (5 samples). The latter could not be identified to species based on mtDNA, and the rostellar hooks were short relative to those described among other Taenia spp. recorded in felids from the Holarctic region. In the phylogenetic analyses of mtDNA sequences, T. laticollis was placed as a sister species of T. macrocystis, and the unknown Taenia sp. was closely related to T. hydatigena and T. regis. Our analyses suggest that these distinct taeniid tapeworms represent a putative new species of Taenia. The only currently recognized definitive host is L. lynx and the intermediate host is unknown.

AbstractIn high-altitude settings of Central Asia the Endangered snow leopard Panthera uncia has been recognized as a potential umbrella species. As a first step in assessing the potential benefits of snow leopard conservation for other carnivores, we sought a better understanding of the presence of other carnivores in areas occupied by snow leopards in China's Qilianshan National Nature Reserve. We used camera-trap and sign surveys to examine whether other carnivores were using the same travel routes as snow leopards at two spatial scales. We also considered temporal interactions between species. Our results confirm that other carnivores, including the red fox Vulpes vulpes, grey wolf Canis lupus, Eurasian lynx Lynx lynx and dhole Cuon alpinus, occur along snow leopard travel routes, albeit with low detection rates. Even at the smaller scale of our camera trap survey all five carnivores (snow leopard, lynx, wolf, red fox and dhole) were observed. Kernel density estimates suggested a high degree of temporal overlap between the snow leopard and the fox, and the snow leopard and the lynx, as indicated by high overlap coefficient estimates. There is an opportunity to consider protective measures at the local scale that would benefit various species simultaneously. However, it should also be recognized that snow leopard conservation efforts could exacerbate human–wildlife conflicts through their protective effect on other carnivore species.
