PUBMED DOIAdditional 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.
