Legionella

Desde su creación hasta la actualidad, La Unidad de Legionella tiene como principal función dar apoyo científico-técnico a la Administración General del Estado, a las Comunidades Autónomas y al Sistema Nacional de Salud en el campo de la prevención y control de la legionelosis, así como llevar a cabo investigaciones científicas en el contexto de la legionelosis. Además, la Unidad de Legionella también actúa como Laboratorio de Referencia de España frente al European Centre for Disease Prevention and Control (ECDC), siendo miembro de la red europea de vigilancia de la legionelosis, “European Legionnaires’ Disease Surveillance Network (ELDSNet). Finalmente, la unidad también realiza una actividad docente, participando en cursos de formación especializada, así como en Máster Universitarios.

 

Principales líneas de investigación

Vigilancia microbiológica

Búsqueda de marcadores moleculares con capacidad de predecir el riesgo de una instalación de provocar legionelosis. Factores de virulencia de Legionella spp.

Estudio de la capacidad formadora de biofilms de Legionella spp. Colonización y dispersión.

Búsqueda de marcadores fenotípicos capaces de discriminar especies del Género Legionella; grupos y subgrupos de Legionella pneumophila.

Diferentes estructuras de biofilms en función de la cepa formadora de Legionella pneumophila. En verde la biomasa bacteriana, en rojo el exopolisacárido de la matriz extracelular.

Apoyo al Sistema Nacional de Salud de la Unidad de Legionella

 

La Unidad de Legionella tambien desarrolla actividades con el fin de proporcionar asistencia al sistema nacional de salud a traves de la oferta disponible en la cartera de servicios del CNM, así como a través de programas de vigilancia microbiológica.

Additional Information

Our general objective is to provide early knowledge about any emerging antibiotic resistance mechanism in our country. This contribution of knowledge is based on transversal objectives that we consider key, such as 1) the ability to adapt research to emerging resistance problems, 2) the promotion of cooperative and multidisciplinary research studies working in networks with different Spanish and foreign centers, 3) the transfer of research results in an agile way to the clinical practice of the national health system, and 4) the promotion of the interrelation of research with reference, advice, training and dissemination seeking the empowerment of all. 

More specifically, our main scientific objectives are the characterization of the molecular bases of antibiotic resistance in pathogenic bacteria, the study of the molecular epidemiology and population structure of resistant bacteria, the characterization of the mobile genetic elements that carry resistance genes, and the development of diagnostic techniques and therapeutic alternatives against bacteria with extensive resistance to antibiotics. In this sense, research into the dissemination pathways of Enterobacteriaceae, Acinetobacter baumannii and carbapenemase-producing Pseudomonas aeruginosa (as a paradigm of extensive resistance and pan-resistance) is one of our current priority objectives.
