Abstract Members of the order Rickettsiales are often found in association with ciliated protists. An interesting case is bacterial endosymbiont “ Candidatus Megaira”, which phylogenetically closely related to pathogen Rickettsia . Megaira” was first described as an intracellular bacterium several ciliate species. Since then it has been diverse evolutionary distantly-related hosts, among them other unicellular eukaryotes, and also algae, metazoa, such cnidarians. We provide characterization...
Taxonomy is the science of defining and naming groups biological organisms based on shared characteristics and, more recently, evolutionary relationships. With birth novel genomics/bioinformatics techniques increasing interest in microbiome studies, a further advance taxonomic discipline appears not only possible but highly desirable. The present work proposes new approach to modern taxonomy, consisting inclusion descriptors organism characterization: (1) presence associated microorganisms...
ABSTRACT. Rickettsia ‐like organisms (RLO) are obligate, often highly fastidious, intracellular bacterial parasites associated with a variety of vertebrate and invertebrate hosts. Despite their importance as causative agents severe mortality outbreaks in farmed aquatic species, little is known about life cycle host range. The present work reports the characterization “ Candidatus Cryptoprodotis polytropus,” novel bacterium common ciliate species Pseudomicrothorax dubius by means “Full‐Cycle...
ABSTRACT. We combined behavioral, morphological (live, stained, scanning and transmission electron‐microscope), molecular data to redescribe two common, intertidal oligotrich ciliates, Novistrombidium testaceum Strombidium inclinatum . Both species were collected from a rocky shore near Leghorn, Ligurian Sea. A literature review revealed four morphotypes of that differ in subtle ways, including oral morphology. These differences may be diagnostic, but we do not consider them sufficient...
ABSTRACT. This study represents the first extended report on a species of ciliathd genus Peritromus , widespread in marine biotopes, characterized by dorso‐ventral differentiation peculiar among Heterotrichea. Morphological observations (live, stained, scanning, and transmission electron microscope) were combined with behavioral molecular data. On basis whole body observations, was recognized as kahli . Scanning microscopy have revealed number features such chalice‐like structures external...
Fibronectin is a component of the extracellular matrix that links collagen fibers to integrins on cell's surface. The splicing isoforms, containing ED-B domain, are not expressed in adult tissues but only tumor stroma or during embryonic development. Fibroblasts and endothelial cells express fibronectin angiogenesis. Also cancer can synthetize fibronectin, its function growth needs be further elucidated.We evaluated expression prostate cell lines: PC3 DU145. Using TGF-β, we induced...
Members of the bacterial order Rickettsiales are obligatorily associated with a wide range eukaryotic hosts. Their evolutionary trajectories, in particular concerning origin shared or differential traits among distant sub-lineages, still poorly understood. Here, we characterized novel bacterium ciliate Paramecium tredecaurelia and phylogenetically related to Rickettsia genus. Its genome encodes significant lineage-specific features, chiefly mevalonate pathway gene repertoire, involved...
Biofouling in water treatment processes represents one of the most frequent causes plant performance decline. Investigation clogged membranes (reverse osmosis membranes, microfiltration and ultrafiltration membranes) is generally performed on fresh membranes. In present study, a multidisciplinary autopsy reverse membrane (ROM) was conducted. The membrane, which used sulfate-rich river purification for drinking purposes, had become inoperative after 6 months because biofouling later stored 18...
Ciliates of the family Sonderiidae are common members eukaryotic communities in various anoxic environments. They host both ecto- and endosymbiotic prokaryotes (the latter associated with hydrogenosomes) possess peculiar morpho-ultrastructural features, whose functions homologies not known. Their phylogenetic relationships other ciliates completely resolved available literature, especially concerning electron microscopy molecular studies, is quite scarce.Sonderia vorax Kahl, 1928 redescribed...
Abstract New pigments with an unprecedented skeleton, named keronopsamides A–C, were isolated from the marine ciliate Pseudokeronopsis riccii . The structure of most abundant secondary metabolite, keronopsamide A, was established through extended Nuclear Magnetic Resonance (NMR) analysis and mass spectrometric (MS) data obtained by using electrospray (ESI) matrix assisted laser desorption (MALDI) ionizations. Structures minor analogues (keronopsamide B C) inferred 1 H NMR, chemical...
Rheinheimera sp. strain EpRS3, isolated from the rhizosphere of Echinacea purpurea, is already known for its ability to produce antibacterial compounds. By use culture experiments, we verified and demonstrated harmful effect against ciliated protist Euplotes aediculatus (strain EASCc1), which by FISH experiments resulted harbor in cytoplasm obligate bacterial endosymbiont Polynucleobacter necessarius (Betaproteobacteria) secondary "Candidatus Nebulobacter yamunensis" (Gammaproteobacteria)....
Abstract We combined morphological (i.e. live, stained, scanning, and transmission electron microscopy) with morphometric molecular analysis to describe a ciliate species collected from shallow reefs in Guam, grown, maintained our laboratory. The was recognized as member of Euplotidium , compared established the genus: itoi Ito 1958; psammophilus (Vacelet 1961) Borror 1972; arenarium Magagnini Nobili 1964; helgae Hartwig 1980; prosaltans Tuffrau 1985, smalli Lei, Choi Xu, 2002. To obtain...
