In recent years, numerous groups have undertaken sequencing of platyhelminth mitochon- drial genomes. Haplorchis taichui (family Heterophyidae) is a trematode that infects humans and animals mainly in Asia, including the Mekong River basin. We sequenced and determined the organization of the complete mitochondrial genome of H. taichui. The mitochondrial genome is 15,130 bp long, containing 12 protein-coding genes, 2 ribosomal RNAs (rRNAs, a small and a large subunit), and 22 transfer RNAs (tRNAs). -

U.S. Fish and Wildlife Service Southeast Region Inventory and Monitoring Branch FY2015 NRPC Final Report Documenting freshwater snail and trematode parasite diversity in the Wheeler Refuge Complex: baseline inventories and implications for animal health. 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. -

Fingerlings of Oreochromis niloticus collected in an artificial urban lake from Belo Horizonte, Minas Gerais, Brazil, were evaluated for natural infection with trematodes. Morphological taxonomic identification of four fluke species was performed in O. niloticus examined, and the total prevalence of metacercariae was 60.7% (37/61). Centrocestus formosanus, a heterophyid found in the gills, was the species with the highest prevalence and mean intensity of infection (31.1% and 3.42 (1–42), resp.), followed by the diplostomid Austrodiplostomum compactum (29.5% and 1.27 (1-2)) recovered from the eyes. Metacercariae of Drepanocephalus sp. and Ribeiroia sp., both found in the oral cavity of the fish, were verified at low prevalences (8.2% and 1.6%, resp.) and intensities of infection (only one metacercaria of each of these species per fish). -

The cysts were counted and used to perform experimental studies (artificial excystment and infection of mice). Fifty specimens ofA. facetus were analyzed and it was found that the prevalence of infection was 100% and mean infection intensity was 134 metacercariae/fish (range: 4-2,510). Significant positive correlations were seen between total fish length and intensity of infection; between fish weight and intensity of infection, and between parasite density and fish length. Morphological analyses on metacercariae and adult parasites obtained from experimentally infected mice made it possible to identify Centrocestus formosanus (Nishigori, 1924). This is the first report ofC. formosanus in A. facetus in Brazil. Keywords: Heterophyidae, fish parasites, metacercariae, trematodes, Minas Gerais, Brazil.

Email address: [email protected] Received December 19, 2015; Accepted May 4, 2016 Abstract Traditionally, people in the Nan Province of Thailand eat raw fish, exposing them to a high risk of getting infected by fish-borne trematodes. The monitoring of helminthiasis among those people showed a high rate of infections by the intestinal fluke Haplorchis taichui, suggesting that also an epidemiologic study (of the epidemiology) of the intermediate hosts of this flat worm would be useful. In this study freshwater gastropods of thiarids and cyprinid fish (possible intermediate hosts) were collected around Bo Kluea and Pua District from April 2012 to January 2013. Both snails and fish were identified by morphology and their infections were examined by cercarial shedding and compressing. Cercariae and metacercariae of H. taichui were identified by morphology using 0.5 % neutral red staining. In addition a polymerase chain reaction of the internal transcribed spacer gene (ITS) was applied to the same samples. Among the three thiarid species present were Melanoides tuberculata, Mieniplotia (= Thiara or Plotia) scabra and Tarebia granifera only the latter species was infected with cercariae, with an infection rate or prevalence of infection of 6.61 % (115/1,740). -

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.
