During my PhD period, I worked on the project "Serious Infections", a surveillance study on a national scale, coordinated by the Istituto Superiore di Sanità. The Microbiological Sciences Department (University of Catania), in fact, had been chosen as a reference center for the south of Italy for the collection of samples isolated from 45 microbiology laboratories, present in various hospitals scattered throughout the national territory (named operative units). During this project, more than 6,000 bacterial strains, coming from the 45 operative units, were isolated, identified, cataloged and stored in a library. The project was renewed thanks to its epidemiological importance in 2008. Thus it became the starting point for my research conducted during the research grant period. The most important data emerging from the surveillance study about "serious infections" was, however, the worrying increase in resistance of some bacterial species against numerous antibiotics, which is currently not balanced by the development of new molecules. This study also highlighted the emergence of multi-drug resistant pathogens, in particular pathogens responsible for nosocomial infections or infections related to health care? These data are particularly worrying from a clinical point of view as they increase the possibility of therapeutic failure with consequent serious implications (increased morbidity, increased lethality, increased duration of the disease, possibility of development of complications, and possibility of epidemics). Without forgetting the economic impact of these infections from multi-resistant bacteria (the additional cost required for the use of additional drugs and more expensive procedures as well as an increased hospital stay. These problems, which have now become a global health emergency, have led me to focus my attention on the problem of overcoming bacterial resistance and on the need to find new substances with antimicrobial activity. Regarding overcoming bacterial resistance and the possibility of improving the activity of drugs already used in clinical practice, I tested the possibility to enlarge the spectrum of activity of glycopeptides to gram-negatives (naturally resistant to these drugs because of the large size of the molecules that cannot pass through the pores of the outer membrane) through encapsulation in drug delivery systems. The encapsulation of vancomycin in SUVETs, fusogenic liposomes able to adhere to and fuse with the outer membrane of gram-negatives bacteria, has had excellent results, allowing the antibiotic to reach the periplasmic space where it has been able to carry out its activity. Regarding the research for new substances with antimicrobial activity, I have been testing the antimicrobial activity of extracts of various kinds, from those of plants to chestnut honey produced on the volcano Mt Etna, with promising results. To stimulate this type of research, since January 2017, I have been part of a spinoff of the University of Catania as a scientific manager, with the aim of using, in an entrepreneurial way, the results of our research. Our mission is basic in vitro research, pre-clinical and clinical research, aimed at the production and marketing in the pharmaceutical, parapharmaceutical, nutraceutical, cosmetic, agricultural, zootechnical and biomedical sectors of innovative products.
