Abstract Book FSFCP.Pdf FSFCP, Sevilla '08 Initial Presentation of the Congress Dear Protistologist, On behalf of “Grupo Especializado de Protistología” and “Groupment de Protistologues de Langue Française”, we have the pleasure to announce you the conjoint celebration in 2008 of their respective meetings. The gathering, called First Spanish-French Congress on Protistology, will be held in Seville, from 4th to 6th June. The aim of this meeting is to promote Protistology in Europe through scientific exchange. Official language is English. We shall make up an attractive scientific program and encourage the active participation of young researchers (pre-, post-docs); the city will provide participants with nice spring weather, history, and charm. The scientific program will be divided in three main axes, Evolution of protists, Biology of free-living protists, and Biology of parasitic protists, with oral presentations and posters. Topics should be set up according to received abstracts. If financial support allows it, two granted talks, opening and closing the meeting, each given by an outstanding protistologue during 60 minutes, are foreseen. Oral communications will be held in morning and afternoon sessions. Every session will include one talk, given by a senior researcher during 45 minutes, five secondary talks, given by young researchers during 20 minutes. All submitted abstracts should be considered as potential for oral presentations; selection will be carried out by the scientific committee of the meeting. Non-selected abstracts should be presented as posters. A session for poster discussion will be included also. 2 FSFCP, Sevilla '08 Organizing Committee Grupo Especializado de Protistología (GEP), Sociedad Española de Microbiología (SEM).

CABIMER-Universidad de Sevilla, Av. Americo Vespucio s/n, 41092 SEVILLA, Spain. [email protected] Transcription takes place on the same substrate as replication, repair and recombination and, not surprisingly, there is a functional and physical interconnection between these processes. A number of conserved factors with a role in mRNP biogenesis, transcription and RNA export show a strong effect on different types of genetic instability, and recent experimental evidence suggests that transcription-mediated hyper-recombination can be mediated by replication-fork impairment. A comparative molecular and genetic analysis of replication fork-progression impairment as a source of hyper-recombination, as well as data on new factors governing repair and hyper-mutation in association with transcription will be presented. Specific emphasis will be made on the relevance of the formation of R-loops as a source of transcription-associated genomic instability. 9 FSFCP, Sevilla '08 Closing Lecture 10 Closing Lecture FSFCP, Sevilla '08 An overview of the new phylogeny of eukaryotes David Moreira. Ecologie, Systématique et Evolution. CNRS Université Paris-Sud. [email protected] The use of molecular information, in particular 18S rRNA sequences, in the late 80s initiated a revolution in the study of the evolutionary relationships among eukaryotes. The first molecular phylogenies showed a stepwise emergence of the different eukaryotic phyla, which supported the idea of a progressive evolution of eukaryotes from very simple forms (the amitochondriate Archezoa) to the complex multicellular groups (animals, plants and fungi). Nevertheless, this paradigm has been challenged in the last decade thanks to the use of alternative molecular markers, especially conserved protein sequences. All known eukaryotes appear to derive from mitochondriate ancestors, which places the origin of mitochondria very early in eukaryotic evolution. Moreover, the topology of the first 18S rRNA-based

Garrity2,3, Charles T. Parker3, Maria Chuvochina4 and Martha E. Trujillo5 Abstract We here present annotated lists of names of Candidatus taxa of prokaryotes with ranks between subspecies and class, pro- posed between the mid- 1990s, when the provisional status of Candidatus taxa was first established, and the end of 2018. Where necessary, corrected names are proposed that comply with the current provisions of the International Code of Nomenclature of Prokaryotes and its Orthography appendix. These lists, as well as updated lists of newly published names of Candidatus taxa with additions and corrections to the current lists to be published periodically in the International Journal of Systematic and Evo- lutionary Microbiology, may serve as the basis for the valid publication of the Candidatus names if and when the current propos- als to expand the type material for naming of prokaryotes to also include gene sequences of yet-uncultivated taxa is accepted by the International Committee on Systematics of Prokaryotes.

  • Molecular Characterisation of Neoparamoeba Strains Isolated from Gills of Scophthalmus Maximus
    DISEASES OF AQUATIC ORGANISMS Vol. 55: 11–16, 2003 Published June 20 Dis Aquat Org Molecular characterisation of Neoparamoeba strains isolated from gills of Scophthalmus maximus Ivan Fiala1, 2, Iva Dyková1, 2,* 1Institute of Parasitology, Academy of Sciences of the Czech Republic and 2Faculty of Biological Sciences, University of South Bohemia, Brani$ovská 31, 370 05 >eské Budeˇ jovice, Czech Republic ABSTRACT: Small subunit ribosomal RNA gene sequences were determined for 5 amoeba strains of the genus Neoparamoeba Page, 1987 that were isolated from gills of Scophthalmus maximus (Lin- naeus, 1758). Phylogenetic analyses revealed that 2 of 5 morphologically indistinguishable strains clustered with 6 strains identified previously as N. pemaquidensis (Page, 1970). Three strains branched as a clade separated from N. pemaquidenis and N. aestuarina (Page, 1970) clades. Our analyses suggest that these 3 strains could be representatives of an independent species. In a more comprehensive eukaryotic tree, strains belonging to Neoparamoeba spp. formed a monophyletic group with a sister-group relationship to Vannella anglica Page, 1980. They did not cluster with Gymnamoebae of the families Hartmannellidae, Flabellulidae, Leptomyxidae or Amoebidae presently available in GenBank.

Several bacteria, including opportunistic human pathogens such as Legionella pneumophila, are able to sur- vive and replicate within protozoan hosts, and certain free-living protozoa are opportunistic human pathogens as well.
