Microbiology

The Microbiology research group of the Vall d'Hebron Research Institute (VHIR) focuses on the study of microbiological aspects —in basic, translational and clinical research— that could improve the outcome of patients with infectious diseases.

Our priority research areas are:

  • Microbiological surveillance of emerging and re-emerging infectious diseases.
    • Diseases due to viral infections of the respiratory tract
    • Microorganisms that cause vaccine-preventable diseases
    • Infectious diseases of sexual transmission
  • Antimicrobial resistance
  • Sepsis
  • Development and validation of rapid microbiological diagnostic devices.
  • International Health
  • Hepatitis 

We actively collaborate with other microbiology laboratories, health services, national and international centres and organizations, as well as with the different research networks of the Carlos III Health Institute in Spain.

In addition, we carry out an important activity in the surveillance of the genotypic and phenotypic evolution of microorganisms present in the community in terms of their virulence, transmissibility, antigenic escape and antimicrobial resistance, in collaboration with public administrations, both at the national and international level.

Antimicrobial Resistance

Antimicrobial resistance is one of the main public health problems recognized by the main public health and sanitary agencies. Enterobacters such as Escherichia coli and Klebsiella pneumoniae, and other bacterial species such as Pseudomonas aeruginosa or Staphylococcus aureus are among the main pathogens causing infections and deaths associated with antimicrobial resistance.


Our research group works on the study of the mechanisms of action and resistance to antimicrobials of these and other bacteria of clinical interest, as well as the study of the mobile genetic elements where their resistance determinants can be found and possible therapeutic alternatives that can be considered to treat the infections they produce. Likewise, we work on the development, application and implementation of state-of-the-art processes, analysis and technologies that allow us to identify the molecular epidemiology, distribution and population structure of multi-resistant bacteria in order to early detect the emergence of high-risk epidemiological clones that can be transferred between patients, producing infections and/or outbreaks related to healthcare.

Development and validation of rapid microbiologic diagnostic devices

Diseases due to viral infections of the respiratory tract

The main objectives of the Respiratory Virus Unit are the microbiological diagnosis of viral respiratory infection, participation in virological surveillance of respiratory viruses, and teaching. In addition to incorporating the state-of-the-art technology for the detection and automation of laboratory processes, we participate in the development and evaluation of new microbiological diagnostic methods in collaboration with the industry. But, beyond being able to detect already known respiratory viruses, and others not so well known, that cause acute respiratory disease in the human population, one of our vocations is virological surveillance. For this, it is necessary to be able to characterize the respiratory viruses detected, either in the community or in the hospitalized population, using genotypic and phenotypic methods, which allow us to better identify them, to know those characteristics that make them of special interest either because their antigenic characteristics have changed, because they have acquired resistance to different antivirals, because they have changed their tropism for other hosts or tissues, or because they are associated with greater severity, among others. In addition, working with new generation sequencing techniques and bioinformatics tools has allowed us to study in depth the viral populations in the host. This work would not be possible if we did not work in a multidisciplinary way with clinical specialists, epidemiologists, mathematicians and public health specialists. But beyond the laboratory results, the products developed and our participation in national and international surveillance networks, we work to disseminate the knowledge acquired, thus contributing to greater awareness of viral respiratory infection and of the viral agents that cause it.

Hepatitis

The liver disease unit is focused on studying the viral hepatitis with a special emphasis on the basic virology, its translational applications, and the evaluation of new serological and virological markers for patient follow-up thanks to the collaboration with both industry and basic/clinical research groups.  Moreover, it is also centred in contributing to the elimination of the hepatitis C virus (HCV), in evaluating HDV epidemiology in high prevalence populations, in inspecting viral variability to determine its relationship with disease progression, immune activation and the development of new therapeutic gene therapy strategies. Of note, the unit is also interested in studying HBV and HDV interaction in collaboration with the gene therapy group of CIMA-University of Navarra.

The study results show that the local presence of IL-1β promotes the development of myeloid cells with an immunosuppressive function.

The project has developed a low-cost system to diagnose malaria and schistosomiasis using artificial intelligence and a robotic microscope.

The collaboration will focus on several key areas of mutual interest in microbiology in particular antimicrobial resistance and stewardship.
