The group ‘Clinical Epidemiology and Vascular Risk’ at the Institute of Biomedicine of Seville—IBiS/University Hospitals Virgen del Rocío and Macarena/CSIC/University of Seville, also a member of CIBERESP, participated in a project with researchers from CIBER-BBN, in which they developed systems to detect Pneumocystis jirovecii, an atypical fungus responsible for very severe pneumonia in immunosuppressed patients. The results have been published in the journals Nanomaterials and Journal of Fungi, and are the fruit of collaboration with the CIBER-BBN groups led by Dr. Laura Lechuga, Dr. Ramon Eritja and Dr. Ramón Martínez Máñez.
