Box 1172, Blindern, 0318 Oslo, Norway c Department of Biology, Tokyo Gakugei University, Koganei, Tokyo 184-8501, Japan article info abstract Article history: The taxonomic affiliation of Hexacontium pachydermum Jørgensen, specifically whether it belongs to the Received 9 April 2009 order Spumellarida or the order Entactinarida, is a subject of ongoing debate. In this study, we sequenced the Received in revised form 3 August 2009 18S rRNA gene of H. pachydermum and of three spherical spumellarians of Cladococcus viminalis Haeckel, Accepted 7 August 2009 Arachnosphaera myriacantha Haeckel, and Astrosphaera hexagonalis Haeckel. Our molecular phylogenetic analysis revealed that the spumellarian species of C. viminalis, A. myriacantha, and A. hexagonalis form a Keywords: monophyletic group. Moreover, this clade occupies a sister position to the clade comprising the spongodiscid Radiolaria fi Entactinarida spumellarians, coccodiscid spumellarians, and H. pachydermum. This nding is contrary to the results of Spumellarida morphological studies based on internal spicular morphology, placing H. pachydermum in the order Nassellarida Entactinarida, which had been considered to have a common ancestor shared with the nassellarians. 18S rRNA gene © 2009 Elsevier B.V.

In Phlebotomus Sergenti (Diptera: Psychodidae)
726 The development of Psychodiella sergenti (Apicomplexa: Eugregarinorida) in Phlebotomus sergenti (Diptera: Psychodidae) LUCIE LANTOVA1,2* and PETR VOLF1 1 Department of Parasitology, Faculty of Science and 2 Institute of Histology and Embryology, First Faculty of Medicine, Charles University in Prague, Czech Republic (Received 1 October 2011; revised 17 November 2011; accepted 18 November 2011; first published online 8 February 2012) SUMMARY Psychodiella sergenti is a recently described specific pathogen of the sand fly Phlebotomus sergenti, the main vector of Leishmania tropica. The aim of this study was to examine the life cycle of Ps. sergenti in various developmental stages of the sand fly host. The microscopical methods used include scanning electron microscopy, transmission electron microscopy and light microscopy of native preparations and histological sections stained with periodic acid-Schiff reaction. Psychodiella sergenti oocysts were observed on the chorion of sand fly eggs. In 1st instar larvae, sporozoites were located in the ectoperitrophic space of the intestine. No intracellular stages were found. In 4th instar larvae, Ps. sergenti was mostly located in the ectoperitrophic space of the intestine of the larvae before defecation and in the intestinal lumen of the larvae after defecation. In adults, the parasite was recorded in the body cavity, where the sexual development was triggered by a blood- meal intake. Psychodiella sergenti has several unique features. It develops sexually exclusively in sand fly females that took a bloodmeal, and its sporozoites bear a distinctive conoid (about 700 nm long), which is more than 4 times longer than conoids of the mosquito gregarines. Key words: Psychodiella, Psychodiella sergenti, gregarine, Phlebotomus sergenti, sand fly, life cycle, PAS, egg, larva, adult. -
Protist Phylogeny and the High-Level Classification of Protozoa
Europ. J. Protistol. 39, 338–348 (2003) © Urban & Fischer Verlag http://www.urbanfischer.de/journals/ejp Protist phylogeny and the high-level classification of Protozoa Thomas Cavalier-Smith Department of Zoology, University of Oxford, South Parks Road, Oxford, OX1 3PS, UK; E-mail: [email protected] Received 1 September 2003; 29 September 2003. Accepted: 29 September 2003 Protist large-scale phylogeny is briefly reviewed and a revised higher classification of the kingdom Pro- tozoa into 11 phyla presented. Complementary gene fusions reveal a fundamental bifurcation among eu- karyotes between two major clades: the ancestrally uniciliate (often unicentriolar) unikonts and the an- cestrally biciliate bikonts, which undergo ciliary transformation by converting a younger anterior cilium into a dissimilar older posterior cilium. Unikonts comprise the ancestrally unikont protozoan phylum Amoebozoa and the opisthokonts (kingdom Animalia, phylum Choanozoa, their sisters or ancestors; and kingdom Fungi). They share a derived triple-gene fusion, absent from bikonts. Bikonts contrastingly share a derived gene fusion between dihydrofolate reductase and thymidylate synthase and include plants and all other protists, comprising the protozoan infrakingdoms Rhizaria [phyla Cercozoa and Re- taria (Radiozoa, Foraminifera)] and Excavata (phyla Loukozoa, Metamonada, Euglenozoa, Percolozoa), plus the kingdom Plantae [Viridaeplantae, Rhodophyta (sisters); Glaucophyta], the chromalveolate clade, and the protozoan phylum Apusozoa (Thecomonadea, Diphylleida). Chromalveolates comprise kingdom Chromista (Cryptista, Heterokonta, Haptophyta) and the protozoan infrakingdom Alveolata [phyla Cilio- phora and Miozoa (= Protalveolata, Dinozoa, Apicomplexa)], which diverged from a common ancestor that enslaved a red alga and evolved novel plastid protein-targeting machinery via the host rough ER and the enslaved algal plasma membrane (periplastid membrane). -

Prevalent Ciliate Symbiosis on Copepods: High Genetic Diversity and Wide Distribution Detected Using Small Subunit Ribosomal RNA Gene
Prevalent Ciliate Symbiosis on Copepods: High Genetic Diversity and Wide Distribution Detected Using Small Subunit Ribosomal RNA Gene Zhiling Guo1,2, Sheng Liu1, Simin Hu1, Tao Li1, Yousong Huang4, Guangxing Liu4, Huan Zhang2,4*, Senjie Lin2,3* 1 Key Laboratory of Marine Bio-resources Sustainable Utilization, South China Sea Institute of Oceanology, Chinese Academy of Science, Guangzhou, Guangdong, China, 2 Department of Marine Sciences, University of Connecticut, Groton, Connecticut, United States of America, 3 Marine Biodiversity and Global Change Laboratory, Xiamen University, Xiamen, Fujian, China, 4 Department of Environmental Science, Ocean University of China, Qingdao, Shandong, China Abstract Toward understanding the genetic diversity and distribution of copepod-associated symbiotic ciliates and the evolutionary relationships with their hosts in the marine environment, we developed a small subunit ribosomal RNA gene (18S rDNA)- based molecular method and investigated the genetic diversity and genotype distribution of the symbiotic ciliates on copepods. Of the 10 copepod species representing six families collected from six locations of Pacific and Atlantic Oceans, 9 were found to harbor ciliate symbionts. Phylogenetic analysis of the 391 ciliate 18S rDNA sequences obtained revealed seven groups (ribogroups), six (containing 99% of all the sequences) belonging to subclass Apostomatida, the other clustered with peritrich ciliate Vorticella gracilis. Among the Apostomatida groups, Group III were essentially identical to Vampyrophrya pelagica, and the other five groups represented the undocumented ciliates that were close to Vampyrophrya/ Gymnodinioides/Hyalophysa. Group VI ciliates were found in all copepod species but one (Calanus sinicus), and were most abundant among all ciliate sequences obtained, indicating that they are the dominant symbiotic ciliates universally associated with copepods. -

Previous work has divided eukaryotic diversity into a small number of high-level ‘supergroups’, many of which receive strong support in phylogenomic analyses. However, the abundance of data in phylogenomic analyses can lead to highly supported but incorrect relationships due to systematic phylogenetic error. Further, the paucity of major eukaryotic lineages (19 or fewer) included in these genomic studies may exaggerate systematic error and reduces power to evaluate hypotheses. -
Supplementary Materials - Methods
Supplementary Materials - Methods Bacterial Phylogeny Using the predicted phylogenetic positions from the Microbial Gene Atlas (MiGA), all complete genomes for the classes betaproteobacteria, alphaproteobacteria, and Bacteroides available on NCBI were collected. The GToTree pipeline was run on each of these datasets, including the Nephromyces endosymbiont, using the relevant HMM set of single copy gene targets (57–62). This included 138 gene targets and 722 genomes in alphaproteobacteria, 203 gene targets and 471 genomes in betaproteobacteria, and 90 gene targets and 388 genomes in Bacteroidetes. In betaproteobacteria, 5 genomes were removed for having either too few hits to the single copy gene targets, or multiple hits. The final trees were created with FastTree v2 (63), and formatted in FigTree (S Figure 2,3). Amplicon Methods Detailed Fifty Molgula manhattensis tunicates were collected from a single floating dock located in Greenwich Bay, RI (41.653N, -71.452W), and 29 Molgula occidentalis were collected from Alligator Harbor, FL (29.899N, -84.381W) by Gulf Specimens Marine Laboratories, Inc. (https://gulfspecimen.org/). All 79 samples were collected in August of 2016 and prepared for a single Illumina MiSeq flow cell (hereafter referred to as Run One). An additional 25 Molgula occidentalis were collected by Gulf Specimens Marine Laboratories, Inc. in March of 2018 from the same location and prepared for a second MiSeq flow cell (hereafter referred to as Run Two). Tunicates were dissected to remove renal sacs and Nephromyces cells contained within were collected by a micropipette and placed in 1.5 ml eppendorf tubes. Dissecting tools were sterilized in a 10% bleach solution for 15 min and then rinsed between tunicates. -

Ключевые слова: фауна, Житомирское Полесье, Волынское Полесье, голые амебы. Introduction Naked amoebae are unicellular eukaryotic organisms that are capable of amoeboid movement. Th is name characterizes morphologically and ecologically similar but not related organisms. According to the current system of eukaryotes (Adl et al., 2012), most of the amoeboid organisms are incorporated into three molecular clusters of unclear taxonomic position. Naked amoebae are among the most important components of aquatic and soil ecosystems. Due to nu- merous diffi culties in species identifi cation, the fauna of these protists remains poorly studied in Ukraine. Pre- vious studies (Patsyuk, 2010, 2011 a, 2011 b, 2012 a, 2012 b, 2014 a, 2014 b; Patcyuk, Dovgal, 2012) recorded 45 species of this group on the territory of Ukraine. -

The glider was found dead in poor body condition. Histologically, large numbers of Parasite zoites were seen predominantly in macrophages in the liver, spleen and lung, with protozoal cysts present in the Protist liver. Molecular and phylogenetic analyses inferred that the protozoan parasite belongs to the family Sarco Sarcocystidae cystidae and is closely related to previously identified apicomplexans found in yellow-bellied gliders (Petaurus australis) in Australia and southern mouse opossums (Thylamys elegans) in Chile. 1.
