The Microbiology Research Group is comprised of three research units conducting fundamental and translational biomedical research to enhance the control of diseases caused by Mycobacterium tuberculosis, M. leprae, and M. ulcerans (Mycobacteriology Unit), arboviruses and HIV (Virology Unit and Experimental Immunology Unit). The group shares common research questions, expertise and technologies in fundamental and translational biomedical research to improve the diagnosis, treatment and surveillance of mycobacteria and viruses in tropical medicine, as well as to understand immunity against these pathogens and exploit it for exploring potentialities for new vaccines.
