Microbiology and Parasitology


The mission of the Microbiology Department is to provide the most efficient diagnosis resources for the study, treatment and prevention of infectious diseases. Microbiology is a multi-disciplinary medical speciality that combines knowledge of the etiology and pathogenesis of infections with knowledge of the technical advances for the faster, more precise identification of microorganisms causing infections, and the most effective antimicrobial treatments.

The Microbiology Department at the University Hospital of Bellvitge forms part of the Regional Clinical Laboratory of the Catalan Health Institute (ICS) Southern Metropolitan Healthcare Region. Along these lines, it receives samples and consultations on patients visiting the Bellvitge, Duran i Reinals, and Viladecans Hospitals, and from patients seen in the primary care centres of our healthcare area.

The Department is certified and operates in line with the requirements of Standard ISO-9001:2015 (Quality policy), and meetings the requirements of the Administrative Authorisation of the Generalitat de Catalunya, according to Decree 76/1995 of 7 March (Official Catalan Journal no. 2031, 29.3.1995), which sets forth the administration authorisation procedure for clinical laboratories and the regulations for their activities.

Its human and material resources are from the ICS, from the University of Barcelona, and from research projects funded by different competitive research organisations.
