II Reunión REDEEX - Santander, 20-21 Septiembre 2010
http://www.redeex.unican.es/
Estimados colegas de REDEEX:
En la anterior reunión REDEEX acordamos que la siguiente reunión (o sea, ésta de Santander) estaría centrada mas en el debate de algunos temas calientes de la biología de EGMs que en la exposición de los resultados específicos de cada grupo. La razón fundamental es evitar repeticiones y conseguir que la reunión sea atractiva para todos, que podamos aprender más y, quizás, favorecer algunas colaboraciones entre laboratorios que tengan intereses similares o complementarios.
Es por ello que en esta ocasión os proponemos un programa dividido en una introducción, cuatro sesiones científicas, y una sesión de conclusiones. El formato concreto de cada sesión dependerá de los participantes que participen en ellas y queda a la espera que nos enviéis la información que os pedimos. En principio se podría pensar que cada sesión consistiría en 2-3 ponencias de 15 min, dedicadas a hacer una revisión del tema y a introducir el debate, seguidas de un debate entre todos, moderado por los ponentes de la sesión.

Summary: Plasmids are key vectors of horizontal gene transfer and essential genetic engineering tools. They code for genes involved in many aspects of microbial biology, including detoxication, virulence, ecological interactions, and antibiotic resistance. While many studies have decorticated the mechanisms of mobility in model plasmids, the identification and characterization of plasmid mobility from genome data are unexplored. By reviewing the available data and literature, we established a computational protocol to identify and classify conjugation and mobilization genetic modules in 1,730 plasmids. This allowed the accurate classification of proteobacterial conjugative or mobilizable systems in a combination of four mating pair formation and six relaxase families. The available evidence suggests that half of the plasmids are nonmobilizable and that half of the remaining plasmids are conjugative. Some conjugative systems are much more abundant than others and preferably associated with some clades or plasmid sizes. Most very large plasmids are nonmobilizable, with evidence of ongoing domestication into secondary chromosomes. The evolution of conjugation elements shows ancient divergence between mobility systems, with relaxases and type IV coupling proteins (T4CPs) often following separate paths from type IV secretion systems. Phylogenetic patterns of mobility proteins are consistent with the phylogeny of the host prokaryotes, suggesting that plasmid mobility is in general circumscribed within large clades. Our survey suggests the existence of unsuspected new relaxases in archaea and new conjugation systems in cyanobacteria and actinobacteria. Few genes, e.g., T4CPs, relaxases, and VirB4, are at the core of plasmid conjugation, and together with accessory genes, they have evolved into specific systems adapted to specific physiological and ecological contexts.

In vivo transmission of a plasmid coharbouring blaDHA-1 and qnrB genes between Escherichia coli and Serratia marcescens
Keywords:
- plasmid-mediated β-lactamases;
- plasmid-mediated quinolone resistance
Abstract We report a Serratia marcescens and an Escherichia coli isolate simultaneously detected in the same patient. Both isolates showed susceptibility patterns suggestive of harbouring a plasmid-mediated AmpC β-lactamase (pACBL) and a plasmid-encoded quinolone resistance (PMQR). PCR-based replicon, MOB typing, plasmid profile and Southern hybridization analyses revealed that both isolates coharboured blaDHA-1 and qnrB genes on the same IncL/M-MOBP13 plasmid approximately 70 kb in size. Together with the fact that both plasmids were conjugative in the laboratory, these results strongly suggest that a horizontal transfer event could take place in vivo. This is the first report of an isolate of S. marcescens harbouring a pACBL. The only phenotypic method that suggests the presence of a pACBL in an isolate harbouring an inducible chromosomal AmpC enzyme is the observation of scattered colonies near the edge of the inhibition zones of some β-lactams. The presence of both resistance genes on the same plasmid and the reported increase in PMQR could perhaps explain the widespread distribution of blaDHA-1 genes.

Cantabria Campus Internacional
The University of Cantabria (UC), which has encouraged and coordinated this collective project, together with the support of the Menéndez Pelayo International University (UIMP), puts forward the design of an International Campus of Excellence, capable of completely fitting in with the University Strategy 2015 to fulfil the objectives of quality, integration and optimisation necessary in higher education in our country.
This project is not presented as an exclusive aim of the University of Cantabria (UC) and the Menéndez Pelayo International University (UIMP), but rather as a Regional Project in which the University plays a central role, social options have been totally involved in supporting a Knowledge society as a distinctive sign of community identity.
The Cantabria International Campus means the maturing of a project which aims to seek excellence in education and the employability of its graduates; in research; in connection with local, national and global society; in the transfer of knowledge to private and public sectors; and in establishing cooperation networks with universities, scientific centres and companies, Spanish as well as foreign ones.
Strategic ObjectivesThe idea of the Cantabria International Campus, which is summarised on the following page, allows it to establish those objectives which will permit it to reach the established vision, starting out from the strategic plans. In the following chart, these objectives are associated with the strategic plans, complying with the generically required objectives, as commented in the stated conditions of the examination.

RESEARCH
To place basic and applied research at a level of international excellence through support and improvement actions which favour acquiring knowledge and attracting and stimulating talent.
TRANSFER
To favour economic development and development in values in society through an efficient transfer of knowledge acquired from research results.
