Clínic Barcelona. Hospital Universitari



In the Bacteriology Section, we develop direct and indirect techniques for diagnosing fungal and bacterial infections. Various units process the clinical samples obtained, attending to their origin and the search for specific pathogens, in order to obtain the maximum yield from the approaches used.

Areas of activity

  • Respiratory tract samples: diagnosis of infections caused by respiratory pathogens
  • Blood culture and culture of sterile fluids: etiologic diagnosis of sepsis, and diagnosis of bacterial meningitis and other infections in biologic fluids
  • Culture of swab material and exudates: diagnosis of various syndromes and infectious conditions from a wide variety of pathologic products
  • Urine culture: urine sedimentation analysis and urine culture study
  • Stool culture: etiologic diagnosis of acute enteritis and traveler’s diarrhea, as well as detection of Clostridium difficile toxin
  • Sexually transmitted disease: etiologic diagnosis of genital infections
  • Mycobacteria: diagnosis of tuberculosis. The Mycobacteria Unit facilities are equipped with special biosafety measures for this purpose.
  • Antibiogram: determination of sensitivity to antibacterial and antifungal agents
  • Epidemiology: studies on the genetic relationships between bacteria for research in epidemiologic outbreaks
  • Mycology: diagnosis of mycoses


Our research lines are focused on the following areas of knowledge related to clinical bacteriology:

  • Development of new diagnostic techniques
  • Pathogenesis of bacterial infections
  • Molecular basis of bacterial antibiotic resistance 

We design and carry out our own research projects and those performed in cooperation with other Departments within Hospital Clínic de Barcelona. We also participate in national and international multicenter studies, and collaborate in the Spanish Network for Research in Infectious Diseases (REIPI, Red Española de Investigación en Patología Infecciosa).


Our educational activity is directed toward:

  • Master and Doctorate degrees in Clinical Microbiology for researchers integrated in the third cycle of university studies
  • Specialist preparation
  • Continuing education for the professional staff of the CDB Microbiology Department
  • Laboratory technician training
