Stefano Ravaioli is a researcher at the Rizzoli Orthopaedic Institute (Bologna). He achieved a Ph.D. in Experimental Pathology in 2010. He worked on several subjects including bacterial molecular epidemiology and the identification of new, emerging, and the most prevalent bacterial clones through different techniques of genotypic characterizations (automated Ribotyping, MLST, spa typing, SCCmec typing, agr typing, PFGE). He extended his experience on biofilm research at the Biofilm Research Group of the University of Calgary in 2008. He improved his genotyping technical skills at the Molecular Genetics Research Group of ITQB/UNL (Oeiras, Portugal) in 2009. He initiated and worked on a project on molecular epidemiology at the Institute of Medical Microbiology and Hygiene (AGES, Vienna) in 2013/2014. Other subjects of study included the analysis of bacterial pathogenic factors (biofilm production, adhesins, toxins, bacterial invasiveness, antibiotic resistance traits); new nanostructured antibacterial films for biomedical applications; pathological interactions between bacteria with eukaryotic cells; and the behavior and interactions of eukaryotic cells exposed to anti-infective substances and the significance of new strategies based on the use of anti-infectives (natural substances, phytocompounds, or antibacterial peptides) to prevent the bacterial adhesion and colonization of biomaterial surfaces.
