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.

Información adicional

The Reference and Research Laboratory for Water-borne an Food-borne Bacterial Diseases (LRIEBTAA) is recognized as a national reference laboratory for the zoonotic agents Salmonella, verotoxigenic Escherichia coli, Yersinia., Campylobacter. and Vibrio (RD 1940/2004 of September 27, Order APA/1808/2007 of June 13). In this sense, its main activity is to ensure adequate surveillance of these zoonoses, zoonotic agents and associated antibiotic resistance, as well as proper investigation of outbreaks caused by these microorganisms. In addition, the LRIEBTAA acts as a reference laboratory for Shigella, other diarrheagenic groups of E. coli, Legionella and toxigenic Corynebacterium species. Added to its reference activity is its applied research activity, among which those mentioned above stand out. 

The members of the group carry out an important training activity. Every year, 3-5 students who develop their final Master's or Degree projects, laboratory technicians in training and rotating students of the specialty of Clinical Microbiology from different national origins are welcomed in the laboratory. In addition, it actively participates in the Public Health microbiologist training program funded by the ECDC through its supervision at the national level and coordination/supervision at the international level.
