Additional Information
Streptococcus pneumoniae is a human pathogen that, despite the development of vaccines, continues to be an important cause of mortality and morbidity. We investigate the mechanisms of antibiotic resistance in this bacterium. On the one hand by identifying new therapeutic targets and on the other hand by investigating the molecular basis of the action of antibiotics already used in clinical practice (the fluoroquinolones levofloxacin and moxifloxacin) or not yet used (seconeolitsine). For this purpose, we used a multidisciplinary analysis involving genomics, transcriptomics and proteomics to understand the organization of the S. pneumoniae chromosome and the identification of the factors that stabilize this organization, including ncRNAs. Changes in the level of global supercoiling, either by inhibition of gyrase (decrease) or by inhibition of topoisomerase I (increase) alter the transcriptome. The modulated genes are located in domains, whose genes show specific functional characteristics. The aim is to identify new factors essential for S. pneumoniae physiology and to characterize transcriptional regulation in response to topological stress. In addition, RNA interference technology and CRISPR systems will be used as novel antibacterials. These studies will establish the bases for translational research aimed at the development of new therapeutic targets for the treatment of pneumococcal diseases.

The current director of CNM is Dr. José Miguel Rubio Muñoz.
Dr. José Miguel Rubio has a degree in Biological Sciences from the Universidad Autónoma de Madrid (1986) and a PhD in Biological Sciences from the same university (1992). He carried out his doctoral thesis at the Department of Genetics of the Universidad Autónoma de Madrid, as Associate Professor (1988-1989), and at the School of Biology of the University of East Anglia in Norwich, UK, as Senior Research Assistant (1989-1992).
During his postdoctoral period he obtained a grant from the European Commission within the Human Capital and Mobility Program to be carried out at the University of “La Sapienza” in Rome, Italy and the Institute of Molecular Biology and Biotechnology in Crete, Greece (1993-1994). Subsequently, he made a further stay funded by the WHO and the university itself at the Department of Entomology, Wageningen University, The Netherlands (1994-1996).
Since 1997 he has been a member of the Instituto de Salud Carlos III (ISCIII), where he joined the Department of Parasitology of the National Center of Microbiology, as an EU-INCO postdoctoral fellow and later with a grant from the Autonomous Community of Madrid (CAM). She was part of the founding group of the National Center for Tropical Medicine (2003-2006) and of the 24/7 Alerts and Emergencies Unit (2006-2018) and is currently Head of the Malaria and Emerging Parasitosis Unit of the National Microbiology Center and is part, as research staff, of the Center for Biomedical Research Network on Infectious Diseases (CIBERINFEC/ISCIII).
During his scientific career he has been Visiting Scientist at the Leonidas e Marie Dean Center (FIOCRUZ-AMAZONAS, Manaus, Brazil) and is an External Consultant of the Parasitology Departments of Cairo University (Egypt) and the Medical Research Center (MRC) of Kuala Lumpur (Malaysia). He also belongs or has belonged to different national and international committees: Member of the expert group for malaria control of the European Centre for Disease Control (ECDC) since 2011; Expert-Evaluator for health programs of the European Commission since 2004; Spanish Representative (commissioned by ISCIII and MSC) in the Technical Scientific Committee of the TDR (WHO) 2007-2008; Spanish Deputy Focal Point for microbiology at the European Centre for Disease Control (ECDC) from 2012 to 2020; and, member of the Research Ethics Committee of ISCIII until 2019.
In this period he has published more than 100 articles in international indexed journals, 10 book chapters and has been co-editor of two books in the area of malaria, tropical medicine and neglected diseases. He has participated in 58 competitively funded research projects, 20 of them international, having been the principal investigator in 8 national and 11 international projects as PI of the project or WP leader. In addition, he has led five agreements with companies. Currently he has been awarded four sexenios of research, being presented this year 2025 to the fifth. In the teaching field, he participates in different postgraduate programs in the areas of microbiology and parasitology, having directed seven doctoral theses and more than 20 Master's or Degree final projects, both nationally and internationally.
El laboratorio de Referencia e Investigación en Resistencia a Antibióticos ofrece una amplia cartera de servicios al Sistema Nacional de Salud, las cuales pueden solicitarse en cnm-laboratorios.isciii.es. Jefe del Laboratorio: Jesús Oteo Iglesias (Punto focal Nacional de Resistencia antibiótica).
Dispone de dos programas de Vigilancia oficiales y gratuitos que engloban los ensayos ofertados ya sea como aislamientos individuales o mediante estudio de brotes. El Laboratorio utiliza asimismo técnicas de PCR en tiempo real para la detección de genes de resistencia, estas técnicas se han adaptado a un formato multiplex que permite detectar varios genes en la misma reacción. En los últimos años se han incluido metodologías basadas en la secuenciación de genomas completos para el análisis de bacterias multiresistentes (WGS).
Programa de vigilancia de Haemophilus influenzae. Responsables: María Pérez Vázquez (Punto focal Nacional de Haemophilus influenzae) y Belén Aracil. Laboratorio encargado de la identificación, estudio de sensibilidad y análisis genotípico de aislados de Haemophilus influenzae, centrándose esencialmente en la patología invasiva debida este patógeno.
Programa de vigilancia de Resistencia a Antibióticos. Responsables: María Pérez Vázquez y Belén Aracil (Punto focal Nacional de Resistencia antibiótica). Laboratorio encargado de la identificación, el estudio de sensibilidad antibiótica, y el diagnóstico fenotípico y genotípico de los diferentes mecanismos de resistencia a antibióticos fundamentalmente en enterobacterias y gram-negativos no fermentadores y Enterococcus spp.
Estudio de brotes. Responsables: Belén Aracil y María Pérez Vázquez. El programa incluye la caracterización de brotes nosocomiales y clones emergentes de alto riesgo mediante diferentes técnicas moleculares (tabla resumen). Éstas, nos permiten realizar estudios filogenéticos con el fin de obtener una información detallada acerca la relación entre los diferentes aislados y su trazabilidad. El objetivo final es generar datos que se transfieren a los hospitales como ayuda para la prevención o control de la propagación del brote.
Acreditación y Calidad. Responsable: Belén Aracil. El laboratorio Referencia e Investigación en Resistencia a Antibióticos ha sido de los primeros en el ISCIII en la utilización de técnicas acreditadas por la Entidad Nacional de Acreditaciones (ENAC). Este laboratorio consiguió la primera acreditación homologada de técnicas diagnósticas en 2012, programa que ha sido ampliado, de manera que en la actualidad más de la mitad de las técnicas ofrecidas al Sistema Nacional de Salud están debidamente acreditadas por ENAC.
Técnicos responsables de las técnicas realizadas en el Laboratorio: Noelia Lara Fuella y Verónica Bautista Sánchez.
En la siguiente imagen se resumen las técnicas ofrecidas al Sistema Nacional de Salud.
