“…However, Casanova et al [15] suggested independent status for them. The results of Haukisalmi et al [13] fully supported the independent status of R. straminea and R. microstoma as host-specific parasites of Apodemus and Mus , respectively, and the present results based on the ITS1 sequences also confirm that they are independent species (data not shown) [GenBank: JN258054 for R. straminea ].…”

BackgroundIn the Canary Islands there are no previous data about tapeworms (Cestoda) of rodents. In order to identify the hymenolepidid species present in these hosts, a survey of 1,017 murine (349 Rattus rattus, 13 Rattus norvegicus and 655 Mus musculus domesticus) was carried out in the whole Archipelago. Molecular studies based on nuclear ITS1 and mitochondrial COI loci were performed to confirm the identifications and to analyse the levels of genetic variation and differentiation.ResultsThree species of hymenolepidids were identified: Hymenolepis diminuta, Rodentolepis microstoma and Rodentolepis fraterna. Hymenolepis diminuta (in rats) and R. microstoma (in mice) showed a widespread distribution in the Archipelago, and R. fraterna was the least spread species, appearing only on five of the islands. The hymenolepidids found on Fuerteventura, Lanzarote and La Graciosa were restricted to one area. The COI network of H. diminuta showed that the haplotypes from Lanzarote and Fuerteventura are the most distant with respect to the other islands, but clearly related among them.ConclusionsFounder effects and biotic and abiotic factors could have played important role in the presence/absence of the hymenolepidid species in determined locations. The haplotypes from the eastern islands (Fuerteventura and Lanzarote) seem to have shared an ancestral haplotype very distant from the most frequent one that was found in the rest of the islands. Two colonization events or a single event with subsequent isolation and reduced gene flow between western-central and eastern islands, have taken place in the Archipelago. The three tapeworms detected are zoonotic species, and their presence among rodents from this Archipelago suggests a potential health risk to human via environmental contamination in high risk areas. However, the relatively low prevalence of infestations detected and the focal distribution of some of these species on certain islands reduce the general transmission risk to human.

“…In our opinion, it should be amended by the inclusion of cricetoid hook shape because the type species of the genus, R. straminea, possesses cricetoid rather than fraternoid, rostellar hooks (see [6][7][8]10,11,17,22,33,[40][41][42][43]). We consider the records of R. straminea with fraternoid rostellar hooks as misidentifications (e.g., [4,5]).…”

“…Species of Nomadolepis significantly differ from species of Rodentolepis (sensu stricto) and its type species R. straminea in several important morphological characters: rostellar hooks of fraternoid type (vs rostellar hooks of cricetoid type); ovary consisting of three lobes (vs fan-shaped); saccate bilobed uterus (vs labyrinthine uterus); uterus not extending beyond osmoregulatory canals (vs uterus extending laterally beyond osmoregulatory canals) [7,8,10,11,17,19,21]. However, due to the lack of a formal revision of Rodentolepis we provide here a [22][23][24] and testes situated in a triangle at an obtuse angle.…”

Broad inconsistent morphological characteristics as well as an unusually broad range of rodent definitive hosts of R. straminea reported by different authors (e.g., [4][5][6][7][8][9][10][11]) suggest that this taxon likely represents a species complex. Originally, Rodentolepis included 12 species [1].…”

Two new species of hymenolepidid cestodes belonging to the genus Nomadolepis are described from small mammals in western Siberia and the Far East, Russian Federation. Nomadolepis fareasta n. sp. is described from the striped dwarf hamster Cricetulus barabensis in Amurskaya Oblast' and Nomadolepis shiloi n. sp. is described from the Eurasian harvest mouse Micromys minutus from Novosibirskaya Oblast' and Amurskaya Oblast'. Nomadolepis fareasta n. sp. differs from Nomadolepis merionis, Nomadolepis ellobii and N. shiloi n. sp. in having a substantially longer strobila, longer cirrus-sac and wider ovary. Furthermore, N. fareasta n. sp. can be readily distinguished from its congeners by the arrangement of the testes and the number and size of rostellar hooks. Nomadolepis shiloi n. sp. differs from N. merionis, N. ellobii and N. fareasta n. sp. by the number and length of the rostellar hooks, the presence of irregular transverse anastomoses as well as the length of the cirrus-sac and position of the cirrus-sac in relation to the poral ventral osmoregulatory canal. Morphological differentiation of the two new species from morphologically similar Palearctic species of the related genus Rodentolepis (sensu lato) from rodents is also provided. Phylogenetic affinities of Nomadolepis were studied for the first time using partial sequences of the nuclear ribosomal 28S DNA gene. Phylogenetic analysis strongly supported the status of Nomadolepis as a separate genus closest to Pararodentolepis.

“…In 1891, Blanchard [5] transferred the species to the genus Hymenolepis and provided an expanded description of the species. Although Bear and Tenora [6] suggested synonymy between H. microstoma and H. straminea (Goeze, 1782), species status of H. microstoma historically has been widely accepted, and molecular data have shown both species to represent independent, albeit closely related, lineages [7,8]. In contrast, the genus Hymenolepis has itself been overhauled on several occasions and its membership and internal structure remain controversial.…”

BackgroundHymenolepis microstoma (Dujardin, 1845) Blanchard, 1891, the mouse bile duct tapeworm, is a rodent/beetle-hosted laboratory model that has been used in research and teaching since its domestication in the 1950s. Recent characterization of its genome has prompted us to describe the specific strain that underpins these data, anchoring its identity and bringing the 150+ year-old original description up-to-date.ResultsMorphometric and ultrastructural analyses were carried out on laboratory-reared specimens of the 'Nottingham' strain of Hymenolepis microstoma used for genome characterization. A contemporary description of the species is provided including detailed illustration of adult anatomy and elucidation of its taxonomy and the history of the specific laboratory isolate.ConclusionsOur work acts to anchor the specific strain from which the H. microstoma genome has been characterized and provides an anatomical reference for researchers needing to employ a model tapeworm system that enables easy access to all stages of the life cycle. We review its classification, life history and development, and briefly discuss the genome and other model systems being employed at the beginning of a genomic era in cestodology.
