Research groups

GC24 Clinical and Molecular Microbiology

The Consolidated Research Group of Clinical and Molecular Microbiology integrates (1) Clinical Microbiology Staff and Residents of the Unit of Microbiology, University Hospital Reina Sofía, (2) Professors of the Department of Microbiology-Medical School, University of Cordoba, and (3) Other Researchers and Technicians with a contractual tie to our group.

The research interests of the group include:

  • Antimicrobial resistance in bacteria of medical interest, with special attention to multiresistant gram-negative organisms.
  • In vitro activity of new antimicrobial agents.
  • Diagnostic methods in Clinical Microbiology.

In the area of major interest for the group (antimicrobial resistance), we consider both Enterobacteria (Escherichia coli, Klebsiella pneumoniae, Enterobacter spp., etc.) and non-fermenters (Pseudomonas aeruginosa and other species, Actinetobacter baumannii and related species, Stenotrophomonas   maltophilia, among others). Other studies are focused on methicillin-resistant Staphylococcus aureus and coryneform bacteria.

Our objectives include: (1) To study mechanisms causing low-level resistance: porin alterations, (over)production of efflux pumps, (2) To study mechanisms of resistance to specific antimicrobial groups, extended-sepctrum beta-lactamases, carbapenemases, plasmid-mediated quinolone resistance, type II topoisomerases, aminoglycoside-modifying enzymes, ARN 16S methyl-transferases)…, and (3) To characterize genes and mobile elements (plasmids, transposons, integrons, gene cassettes, etc.) involved in antimicrobial resistance.

We are also considering molecular epidemiology of multiresistant bacteria causing nosocomial infections, and the study of the relationship between antimicrobial resistance and virulence.

The achievements of our research include:

  • Discovery of qnr genes, causing plasmid-mediated quinolone resistance. Detailed contribution of these genes to resistance and design of molecular methods for their detection.
  • Demonstration of the importance of porins in of low-level resistance.
  • Analysis of penicillin-binding proteins of multiresistant A. baumannii.
  • Characterization of mechanisms of resistance to aminoglycosides in multiresistant enterobacteria, non-fermenters and corynebacteria.
  • Demonstration of the importance of manganese contents in culture media when testing tigecycline.
  • Collaboration in multiples clinical studies on treatment and prognosis of infections caused by multiresistant bacteria.

We contribute to the Programs “Resistance”  and “Infections in Transplanted Patients” of the Spanish network for research on infectious diseases (REIPI, http://reipi.org/)  supported by the  Institute of Health Carlos III  (ISCIII). This network has developed and is developing different multicenter studies on clinical and microbiological aspects of infections caused by resistant bacteria of clinical relevance.

Research Lines

  • Beta-lactamases: Identification of genes coding for extended-espectrum beta-lactamases, AmpC-type beta-lactamases, carbapenemases and other beta-lactamases of clinical importance.
  • Plasmid-mediated quinolone resistance: Qnr proteins and related mechanisms.
  • Mechanisms of aminoglycoside resistance: Modifying enzymes and ARN 16S methyl-transferases.
  • Low level resistance mechanisms, with interest in outer membrane proteins (particularly porins in enterobacterias and in Pseudomonas spp.) and efflux pumps.
  • Heteroresistance to antimicrobial agents, focused on carbapenem and polymyxins.
  • Genetic elements involved in horizontal gene transfer and its relevance for antimicrobial resistance.
  • Bacterial targets: Escherichia coli, Klebsiella pneumoniae, Enterobacter spp., other enterobacterias, Pseudomonas aeruginosa (and related species), Acinetobacter baumannii complex, Stenotrophomonas maltophilia, Staphylococcus aureus, coagulase-negative staphylococci, Corynebacterium and related genera.
  • Development of new antimicrobial agents: chelocardin, new aminoglycosides.
  • In vitro studies of new compounds, in collaboration with the pharmaceutical industry.
  • Evaluation of Maldi-Tof for identification of microorgansims of clinical importance, including both bacteria and fungi.
  • Use of molecular methods for identification of clinically important microorganisms.
  • Evaluation of new commercial methods and assays for microbiological diagnosis.
  • Evaluation of commercial and in-house methods for susceptibility testing of bacteria of clinical interest.
