    ABSTRACT Title of Dissertation: IDENTIFICATION, LIFE HISTORY

    ABSTRACT Title of Dissertation: IDENTIFICATION, LIFE HISTORY, AND ECOLOGY OF PERITRICH CILIATES AS EPIBIONTS ON CALANOID COPEPODS IN THE CHESAPEAKE BAY Laura Roberta Pinto Utz, Doctor of Philosophy, 2003 Dissertation Directed by: Professor Eugene B. Small Department of Biology Adjunct Professor D. Wayne Coats Department of Biology and Smithsonian Environmental Research Center Epibiotic relationships are a widespread phenomenon in marine, estuarine and freshwater environments, and include diverse epibiont organisms such as bacteria, protists, rotifers, and barnacles. Despite its wide occurrence, epibiosis is still poorly known regarding its consequences, advantages, and disadvantages for host and epibiont. Most studies performed about epibiotic communities have focused on the epibionts’ effects on host fitness, with few studies emphasizing on the epibiont itself. The present work investigates species composition, spatial and temporal fluctuations, and aspects of the life cycle and attachment preferences of Peritrich epibionts on calanoid copepods in Chesapeake Bay, USA. Two species of Peritrich ciliates (Zoothamnium intermedium Precht, 1935, and Epistylis sp.) were identified to live as epibionts on the two most abundant copepod species (Acartia tonsa and Eurytemora affinis) during spring and summer months in Chesapeake Bay. Infestation prevalence was not significantly correlated with environmental variables or phytoplankton abundance, but displayed a trend following host abundance. Investigation of the life cycle of Z. intermedium suggested that it is an obligate epibiont, being unable to attach to non-living substrates in the laboratory or in the field. Formation of free-swimming stages (telotrochs) occurs as a result of binary fission, as observed for other peritrichs, and is also triggered by death or molt of the crustacean host.

    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).

Thus, exploration on the capacity of parasitic pathogens in relation to reproductive losses in this species are needed. This was the first study investigating, simultaneously, the role and changes induced by Neospora caninum, Toxoplasma gondii and Besnoitia besnoiti in water buffaloes in southern Italy. The outcome of this study revealed a high exposure of water buffaloes to both N. caninum and T. gondii, whereas all the animals resulted negative to B. besnoiti. The mono-infection with N. caninum seems mainly associated with abortion and presence of retained foetal membranes, while mono-infection with T.

This article is published with open access Abstract The giant colonial ciliate Zoothamnium niveum harbors a monolayer of the gammaproteobacteria Cand. Thiobios zoothamnicoli on its outer surface. Cultivation experiments revealed maximal growth and survival under steady flow of high oxygen and low sulfide concentrations. We aimed at directly demonstrating the sulfur-oxidizing, chemoautotrophic nature of the symbionts and at investigating putative carbon transfer from the symbiont to the ciliate host. We performed pulse-chase incubations with 14C- and 13C-labeled bicarbonate under varying environmental conditions. A combination of tissue autoradiography and nanoscale secondary ion mass spectrometry coupled with transmission electron microscopy was used to fi 1234567890();,: follow the fate of the radioactive and stable isotopes of carbon, respectively. We show that symbiont cells x substantial amounts of inorganic carbon in the presence of sulfide, but also (to a lesser degree) in the absence of sulfide by utilizing internally stored sulfur. Isotope labeling patterns point to translocation of organic carbon to the host through both release of these compounds and digestion of symbiont cells. The latter mechanism is also supported by ultracytochemical detection of acid phosphatase in lysosomes and in food vacuoles of ciliate cells.

Simple Summary: Alveolates are a major group of free living and parasitic organisms; some of which are serious pathogens of animals and humans. Apicomplexans and chromerids are two phyla belonging to the alveolates. Apicomplexans are obligate intracellular parasites; that cannot complete their life cycle without exploiting a suitable host. Chromerids are mostly photoautotrophs as they can obtain energy from sunlight; and are considered ancestors of the apicomplexans. The pathogenicity and life cycle strategies differ significantly between parasitic alveolates; with some causing major losses in host populations while others seem harmless to the host. As the life cycles of Citation: Kristmundsson, Á.; Erlingsdóttir, Á.; Lange, S. some are still poorly understood, a better understanding of the factors which can affect the parasitic Peptidylarginine Deiminase (PAD) alveolates’ life cycles and survival is of great importance and may aid in new biomarker discovery. and Post-Translational Protein This study assessed new mechanisms relating to changes in protein structure and function (so-called Deimination—Novel Insights into “deimination” or “citrullination”) in two key parasites—an apicomplexan and a chromerid—to Alveolata Metabolism, Epigenetic assess the pathways affected by this protein modification.
  • Exceptional Species Richness of Ciliated Protozoa in Pristine Intertidal Rock Pools

    Exceptional Species Richness of Ciliated Protozoa in Pristine Intertidal Rock Pools

    MARINE ECOLOGY PROGRESS SERIES Vol. 335: 133–141, 2007 Published April 16 Mar Ecol Prog Ser Exceptional species richness of ciliated Protozoa in pristine intertidal rock pools Genoveva F. Esteban*, Bland J. Finlay School of Biological & Chemical Sciences, Queen Mary, University of London, London E1 4NS, UK ABSTRACT: Marine intertidal rock pools can be found almost worldwide but little is known about the microscopic life forms they support, or the significance of regular tidal inundation. With regard to ciliated Protozoa in rock pools, little progress has been achieved since 1948, when the question was first posed as to how a community of ciliates can remain relatively constant in a rock pool that is flushed twice a day. Here we show that local ciliate species richness is very high and that it may per- sist over time. This elevated species richness can be attributed to ciliate immigration with the in- coming tide, and also to the resident ciliate community that withstands tidal flushing. A 15 cm deep intertidal rock-pool no bigger than 1 m2 on the island of St. Agnes (Scilly Islands, UK) contained at least 85 ciliate species, while a 20 cm-deep rock pool with roughly the same area on Bryher (also in the Scilly Islands) yielded 75 species. More than 20% of the global number of described marine inter- stitial ciliate species was recorded from these rock pools. We explore the paradox of a persisting com- munity assembly living in an ecosystem that is physically highly dynamic.

Notably, the development of megalomeronts by species of Haemoproteus and Leucocytozoon has been associated with mortalities in birds. Diagnosis of lethal infections is currently accomplished by the detection of parasites’ tissue stages in histological sections combined with PCR and sequencing. However, sequences frequently are not reliably obtained and the generic discrimination of exo‑eryth‑ rocytic tissue stages based on morphological characters is challenging. Therefore, the present study aimed at devel‑ oping specifc molecular probes for the identifcation of Haemoproteus spp. and Leucocytozoon spp. in histological sections using chromogenic in situ hybridization. Methods: Parasite subgenus‑specifc oligonucleotide probes were designed to target the 18S ribosomal RNA of Haemoproteus species (subgenus Parahaemoproteus) and Leucocytozoon spp. (subgenus Leucocytozoon) and were in situ hybridized to sections from formalin‑fxed, parafn‑embedded tissue samples determined positive for these parasites by PCR and histopathology. To confrm the presence of parasites at sites of probe hybridization, consecutive sections were stained with haematoxylin–eosin and examined. Results: Parahaemoproteus‑ and Leucocytozoon‑specifc probes labelled erythrocytic and exo‑erythrocytic stages of Haemoproteus spp.
