PUBMED DOIInformación adicional
1.- The study of non-gastrointestinal zoonoses, some of them transmitted by vectors and/or emerging, aims to:
- The development and validation of new diagnostic and genotyping techniques represent important scientific-technical support to the National Health System, acting as a reference laboratory.
- Research on the Molecular Epidemiology of Coxiella burnetii studies the circulating genotypes and their association with the different clinical presentations of Q fever.
- Discovery of new pathogens: especially relevant in the case of Francisella with the description of F. hispaniensis, as well as taxonomically unknown variants of Bartonella, Borrelia and Rickettsia, found in reservoirs, vectors and clinical samples.
- Surveillance in nature analyzes kinetics, transmission cycles and reservoirs.
• Genotyping techniques allow traceability studies to be carried out in the case of natural outbreaks or intentional release. • Method accreditation: ISO15189 standard (clinical samples), ISO17025 (environmental).
2.- The study of bacteria with potential use in bioterrorism through participation in European projects (Joint Actions: QUANDHIP, EMERGE, SHARP) allows us to respond appropriately to possible health alert situations. An important methodological development has been carried out for the detection of these agents and a Rapid Response System has been implemented.
