Echinostome trematode parasites have complex, multiple-host life-cycles, often involving migratory bird definitive hosts, thus leading to widespread distributions. Here, we examined the echinostome diversity in freshwater ecosystems at high latitude locations in Iceland, Finland, Ireland and Alaska (USA). We report 14 echinostome species identified morphologically and molecularly from analyses of nad1 and 28S rDNA sequence data. We found echinostomes parasitising snails of 11 species from the families Lymnaeidae, Planorbidae, Physidae and Valvatidae. -

During a survey of helminth parasites of the brown ground snake, Atractus major Boulenger, 1894 (Serpentes: Dipsadidae) from Moyobamba, region of San Martin (northeastern Peru), a new species of Glossidiella Travassos, 1927 (Plagiorchiida: Plagiorchiidae) was found and is described herein based on morphological and ultrastructural data. The digeneans found in the lung were measured and drawings were made with a drawing tube. The ultrastructure was studied using scanning electron microscope. Glossidiella peruensis sp. nov. is easily distinguished from the type- and only species of the genus, Glossidiella ornata Travassos, 1927, by having an oblong cirrus sac (claviform in G. -
Somatic Musculature in Trematode Hermaphroditic Generation Darya Y
Krupenko and Dobrovolskij BMC Evolutionary Biology (2015) 15:189 DOI 10.1186/s12862-015-0468-0 RESEARCH ARTICLE Open Access Somatic musculature in trematode hermaphroditic generation Darya Y. Krupenko1* and Andrej A. Dobrovolskij1,2 Abstract Background: The somatic musculature in trematode hermaphroditic generation (cercariae, metacercariae and adult) is presumed to comprise uniform layers of circular, longitudinal and diagonal muscle fibers of the body wall, and internal dorsoventral muscle fibers. Meanwhile, specific data are few, and there has been no analysis taking the trunk axial differentiation and regionalization into account. Yet presence of the ventral sucker (= acetabulum) morphologically divides the digenean trunk into two regions: preacetabular and postacetabular. The functional differentiation of these two regions is already evident in the nervous system organization, and the goal of our research was to investigate the somatic musculature from the same point of view. Results: Somatic musculature of ten trematode species was studied with use of fluorescent-labelled phalloidin and confocal microscopy. The body wall of examined species included three main muscle layers (of circular, longitudinal and diagonal fibers), and most of the species had them distinctly better developed in the preacetabuler region. In majority of the species several (up to seven) additional groups of muscle fibers were found within the body wall. Among them the anterioradial, posterioradial, anteriolateral muscle fibers, and U-shaped muscle sets were most abundant. These groups were located on the ventral surface, and associated with the ventral sucker. The additional internal musculature was quite diverse as well, and included up to twelve separate groups of muscle fibers or bundles in one species. -

Echinostoma miyagawai Es. miyagawai belongs to the “37 collar-spined” or “revolutum” group, which is very difficult to identify and Echinostomatidae classify based only on morphological characters. Molecular techniques can resolve this problem. The present Mitochondrial genome study, for the first time, determined, and presented the complete Es. miyagawai mitochondrial genome. A Comparative analysis comparative analysis of closely related species, and a reconstruction of Echinostomatidae phylogeny among the Phylogenetic analysis trematodes, is also presented. The Es. miyagawai mitochondrial genome is 14,416 bp in size, and contains 12 protein-coding genes (cox1–3, nad1–6, nad4L, cytb, and atp6), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs), and one non-coding region (NCR). All Es. miyagawai genes are transcribed in the same direction, and gene arrangement in Es. miyagawai is identical to six other Echinostomatidae and Echinochasmidae species. The complete Es. miyagawai mitochondrial genome A + T content is 65.3%, and full- length, pair-wise nucleotide sequence identity between the six species within the two families range from 64.2–84.6%. -

Lori Tolley-Jordan Prepared by: Lori Tolley-Jordan Project ID: Grant Agreement Award# F15AP00921 1 Report Date: April, 2017 U.S. Fish and Wildlife Service Southeast Region Inventory and Monitoring Branch FY2015 NRPC Final Report Title: Documenting freshwater snail and trematode parasite diversity in the Wheeler Refuge Complex: baseline inventories and implications for animal health. Principal Investigator: Lori Tolley-Jordan, Jacksonville State University, Jacksonville, AL. ______________________________________________________________________________ ABSTRACT The Wheeler National Wildlife Refuge (NWR) Complex includes: Wheeler, Sauta Cave, Fern Cave, Mountain Longleaf, Cahaba, and Watercress Darter Refuges that provide freshwater habitat for many rare, endangered, endemic, or migratory species of animals. To date, no systematic, baseline surveys of freshwater snails have been conducted in these refuges. Documenting the diversity of freshwater snails in this complex is important as many snails are the primary intermediate hosts of flatworm parasites (Trematoda: Digenea), whose infection in subsequent aquatic and terrestrial vertebrates may lead to their impaired health. In Fall 2015 and Summer 2016, snails were collected from a variety of aquatic habitats at all Refuges, except at Mountain Longleaf and Cahaba Refuges. All collected snails were transported live to the lab where they were identified to species and dissected to determine parasite presence. Trematode parasites infecting snails in the refuges were identified to the lowest taxonomic level by sequencing the DNA barcoding gene, 18s rDNA. Gene sequences from Refuge parasites were matched with published sequences of identified trematodes accessioned in the NCBI GenBank database. -

At least 56 nominal species have been described in this group. However, many of them were morphologically close to and difficult to distinguish from the other, thus synonymized with the others. However, some of the synonymies were disagreed by other researchers, and taxonomic debates have been continued. Fortunately, recent development of molecular techniques, in particular, sequencing of the mitochondrial (nad1 and cox1) and nuclear genes (ITS region; ITS1-5.8S-ITS2), has enabled us to obtain highly useful data on phylogenetic relationships of these 37-collar-spined Echinostoma spp. Thus, 16 different species are currently acknowledged to be valid worldwide, which include E. revolutum, E. bolschewense, E. caproni, E. cinetorchis, E. deserticum, E. lindoense, E. luisreyi, E. me- kongi, E. miyagawai, E. nasincovae, E. novaezealandense, E. -

Adult trematodes from eight families as well as cercariae and metacercariae from ten families were studied. TRITC-conjugated phalloidin was used to stain the muscle fi bres. The serotonin- and FMR- Famide-immunoreactive (IR) nerve cells and fi bres were revealed to be near the muscle fi bres of the oral and ventral suckers of the trematodes and their larvae. The results indicate the important role of neurotransmitters, serotonin and neuropeptide FMRFamide in the regulation of muscle activity in the attachment organs of trematodes and can be considered in perspective for the development of new anthelmintic drugs, which can interrupt the function of the attachment organs of the parasites.

Its comparative analysis provides a great contribution to evolu- RNA secondary structure tionary biology, allowing find out how the SSU rRNA secondary structure originated, developed and evolved. Molecular evolution Herein, we provide the first data on the putative SSU rRNA secondary structures of the Plagiorchiida species.The Taxonomy structures were found to be quite conserved across broad range of species studied, well compatible with those of others eukaryotic SSU rRNA and possessed some peculiarities: cross-shaped structure of the ES6b, additional shortened ES6c2 helix, and elongated ES6a helix and h39 + ES9 region. The secondary structures of variable regions ES3 and ES7 appeared to be tissue-specific while ES6 and ES9 were specific at a family level allowing considering them as promising markers for digenean systematics. Their uniqueness more depends on the length than on the nucleotide diversity of primary sequences which evolutionary rates well differ. The findings have important implications for understanding rRNA evolution, developing molecular taxonomy and systematics of Plagiorchiida as well as for constructing new anthelmintic drugs. -
