Higgins Lab - Dynamics of antimicrobial resistance
We are using whole genome sequencing, short and long read sequencing platforms (Illumina MiSeq and Oxford Nanopore MinION platforms, respectively), and traditional molecular biology methods to investigate the dynamics of antimicrobial resistance, antimicrobial resistance mechanisms and the molecular epidemiology of hospital-associated pathogens (with a focus on ESKAPE organisms) as well as community associated pathogens such as Neisseria gonorrhoeae and Mycobacterium tuberculosis. We investigate and track bacterial isolates in multicenter national and international surveillance studies, to understand the transmission of bacteria and the movement of mobile genetic elements and resistance determinants between patients and hospital, as well in the wider environment, and in a One-Health approach. Novel antimicrobials and diagnostic tools, and therapeutic use of phage are also investigated. We are very active in DZIF HAARBI, working on various multicentre projects including AEGON, R-NET, and TIARA.
