This unit is focused on the study at the phenotypic, genomic and protein leves of pathogenic bacteria of veterinary interest. The main activities of the Unit are divided into three research lines that are closely related: clinical diagnosis (using phenotypic, molecular and chemotaxonomic methods, the molecular characterization of pathogenic bacteria of relevant clinical significance for epidemiological purposes and description of new bacterial species (bacterial taxonomy). The molecular characterization allows tracing epidemiological links between strains associated with outbreaks of disease, global epidemiological studies, monitoring programs, etc. Studies of bacterial taxonomy not only allow the description of new species but also allow, for example, the association of different pathogens with atypical clinical processes. Additionally, this unit integrates the Mass Spectrometry VISAVET- Bruker Platform enabling developing proteomics research studies in the field of microbiology and molecular histology.

VISAVET-BRUKER Mass Spectrometry


This platform was acquired in the 2011 call of the Equipment Acquisition and Scientific-Technical Infrastructure Adequacy (CAIMON) of Campus MONCLOA and enable the constitution of a service to enhance the research on campus.

The VISAVET-BRUKER service is made within the framework of a collaboration agreement between the Complutense University and Bruker Daltonik GMBH.


Application for identification and classification of bacteria and fungi. The identification is based on the comparison of the spectral fingerprints of the microorganism with those existing in the database (composed for more than 4000 entries). The technique is an accurate, simple, fast and reliable alternative for the identification of bacteria with traditional methods.

 MALDI BIOTYPER analysis services (coming soon)


Application of MALDI TOF MS for the two dimensional acquisition of mass spectra from fresh tissue section. Image MALDI is ideal for the identification of protein markers and other small molecules in tissue sections.

 IMAGE MALDI analysis services (coming soon)

LC-MALDI system

System allowing the identification of proteins primarily by determining its peptide fingerprint. Enables Proteomics studies.

 Servicios de Análisis por LC-MALDI (coming soon)
