Title of the research project: "Genomic approach for the identification of resistance mechanisms to new antibiotics and inhibitors of
resistance mechanisms in clinically relevant Gram-negative bacteria"

Thematic area: Molecular Biology, Microbiology,
SSD:Bio/19
Brief description:
This project is based on Whole Genome Sequencing (WGS) techniques, performed by rapid methods like the ONT (Oxford
Nanopore Technologies), in part complemented by Illumina sequencing. WGS is applied on key bacterial strains, with the aim
to identify endemic clones circulating in hospitals, animals, and the environment and to describe their evolution in a global
perspective. Since WGS allows the identification of microbial markers predicting and orienting empiric therapy of sepsis in
critical patients, information obtained with these studies will be used to build rapid bacterial typing methods and to follow
colonization and/or infection in critical patients. Owing to its capacity to collect multiple antimicrobial-resistance determinants, Klebsiella pneumoniae is one of the biggest threats to public health. In Italy
the dissemination of multidrug-resistant K. pneumoniae is driven by few high-risk clones expressing the KPC carbapenemase
enzyme, such as those belonging to the Clonal Groups (CGs) 101, 147, 258 and 307. I have been responsible for sequencing through the Oxford Nanopore Technologies MinION platform and Illumina platform bacteria resistant to new drugs, identifying the mechanisms
of resistance and of horizontal gene transfer
