Resistencia a Antibióticos

Nuestro objetivo general es aportar conocimiento precoz sobre cualquier mecanismo de resistencia a antibióticos emergente en nuestro país. Dicho aporte de conocimiento se fundamenta en unos objetivos transversales clave:

  1) La capacidad de adaptar la investigación a los problemas de resistencia emergentes

  2) La promoción de estudios de investigación cooperativos y multidisciplinares con diferentes centros españoles y extranjeros

  3) La transferencia ágil de los resultados de la investigación a la práctica clínica del Sistema Nacional de Salud

  4) El fomento de la interrelación de la investigación con la referencia, la asesoría, la formación y la divulgación.

Nuestros principales objetivos científicos son la caracterización de las bases moleculares de la resistencia a antibióticos en bacterias patógenas, el estudio de la epidemiología molecular y la estructura poblacional de las bacterias resistentes, la caracterización de los elementos genéticos móviles que portan los genes de resistencia, y el desarrollo de técnicas diagnósticas y alternativas terapéuticas frente a bacterias con resistencia extensa, basado en nuevas tecnologías como la secuenciación de genomas bacterianos. La investigación en las vías de diseminación de enterobacterias, Acinetobacter baumannii y Pseudomonas aeruginosa productores de carbapenemasas es uno de nuestros objetivos prioritarios.


Algunas iniciativas en las que participamos son la red europea de vigilancia de la resistencia a antibióticos (EARS-Net), el  sistema de la OMS desarrollado para apoyar el plan de acción mundial sobre la resistencia a los antimicrobianos (GLASS), la red española de investigación en patología infecciosa (REIPI), el Plan nacional contra la resistencia a antibióticos (PRAN), el Comité Coordinador de la red de laboratorios para la vigilancia de microorganismos resistentes, y la coordinación nacional de los proyectos CARBA-ES-2019 (nacional) y CCRE-survey (ECDC).

Líneas de investigación

- Detección y caracterización de mecanismos de resistencia a antibióticos emergentes, sobre todo a antibióticos de última línea como los antibióticos carbapenémicos y la colistina.


- Caracterización y trazabilidad interregional, mediante el análisis de secuencias de genomas completos (WGS), de clones de alto riesgo con múltiple resistencia a antibióticos, y de plásmidos epidémicos portadores de genes de resistencia.


- Identificación mediante recursos bio-informáticos de posibles dianas para el desarrollo de nuevos productos o moléculas relacionadas con el control de la resistencia a antibióticos (vacunas, pruebas diagnósticas, atenuantes de virulencia y otros).


- Análisis de las tendencias evolutivas de la resistencia a antibióticos en patógenos bacterianos productores de bacteriemia; European Antimicrobial Resistance Surveillance Net (EARS-Net) del ECDC y Global Antimicrobial Resistance Surveillance System (GLASS) de la OMS.


- Análisis del microbioma y resistoma del tracto gastrointestinal humano y su relación con la colonización por bacterias multi-resistentes y desarrollo de infecciones (metagenómica).

Investigación en infecciones multirresistentes

 

La emergencia y diseminación global de cepas bacterianas de diferentes especies con resistencia a distintas clases de antibióticos (cepas multirresistentes) supone una amenaza para la eficacia del tratamiento antibiótico. El Antibiotic Resistance Global Report publicado por la Organización Mundial de la Salud en 2014 destacó altas tasas de resistencia en varias especies de bacterias patógenas en cada una de las seis regiones incluidas en el estudio (WHO; 2014). Las infecciones causadas por bacterias resistentes están asociadas a una mortalidad significativa, produciendo más de 700.000 muertes al año, y se estima que esta cifra llegará a 10 millones de muertes anuales en 2050, si no cambia la tendencia actual (Antimicrobial Resistance Rev; 2015). En 2017, la Organización Mundial de la Salud identificó las especies bacterianas frente a las que deberían implementarse nuevas medidas de tratamiento y prevención (WHO 2017). En este informe se clasificaron las especies Gram negativas multirresistentes.

Acinetobacter baumanniiPseudomonas aeruginosa y Klebsiella pneumoniae con la prioridad más alta (Priority 1: Critical). Las tasas de resistencia a los antimicrobianos de primera línea de estas bacterias Gram-negativas multirresistentes se han incrementado a nivel global durante la última década, complicando significativamente el manejo clínico de las infecciones producidas por estos microorganismos. En este contexto, nuestro grupo está desarrollando las siguientes líneas de investigación:

1. Desarrollo de vacunas para infecciones multirresistentes

Esta línea de investigación tiene como objetivo del desarrollo preclínico de vacunas profilácticas y anticuerpos monoclonales terapéuticos para infecciones producidas por bacterias Gram negativas multirresistentes de difícil manejo clínico debido a la resistencia antimicrobiana. La investigación realizada en esta línea tiene como objetivo identificar y caracterizar antígenos de las bacterias multirresistentes (Acinetobacter baumannii, Klebsiella pneumoniae y Pseudomonas aeruginosa) que sirvan para el desarrollo de anticuerpos monoclonales y vacunas a través de estudios epidemiológicos, genómicos y proteómicos.

2. Caracterización de tratamientos novedosos para infecciones multirresistentes

Esta línea de investigación tiene como objetivo identificar y caracterizar nuevos tratamientos basados en moléculas novedosas y/o combinaciones de antibióticos existentes para infecciones producidas por bacterias Gram negativas multirresistentes.  También se emplean técnicas moleculares y "omicas" para la identificación de nuevas dianas para el desarrollo de antibióticos novedosas. 

3. Desarrollo de vacunas frente a SARS-CoV-2

Debido la situación producida por la propagación del SARS-CoV-2 urge la realización de estudios que tienen como objetvo el desarrollo de vacunas profilácticas.  Nuestro grupo lidera el desarrollo de un prototipo de vacuna basado en ADN plasmídico que expresa antígenos de SARS-CoV-2 y la caracterización de la respuesta inmune inducida por esta vacuna en un modelo murino de inmunización.

Despite progress, parasitic diseases remain a major challenge for humans. Its rapid and accurate detection, as well as the identification of specific genes related to virulence and/or resistance to treatments, is a necessity for management and planning control strategies. 

The main objective of the group is to carry out quality, competitive and innovative research, to acquire, disseminate and apply in clinical parasitology with the ultimate goal of improving and innovating in the diagnoses, therapies and control of parasitic diseases. This general objective is implemented through external projects and collaborations with different funding sources:

- Characterization of submicroscopic malaria. National Hospital Network. (FIS-ISCIII).
- Design, optimization and validation of advanced diagnostic methods for the detection of blood parasites (Retos-MICINN).
- Control of onchocerciasis in Equatorial Guinea. CNMTrop-ISCIII (Task Force, USA).
- Characterization and control of Mansonellosis and Onchocerciasis in the Amazon region in Brazil. FIOCRUZ from Amazonas, Brazil. (Cpnqt-Brazil).
- Plasmodium knowlesi and its implication as the fifth species of human malaria. MRC, Malaysia.
- Intestinal parasitosis in Egypt from Cryptosporidium (protozoan) to Capillaria (Nematode). Cairo University and Al-Azhar University, Egypt. (MHESR, AECID).
