Overview

Our research focuses on β-lactamase-producing antimicrobial-resistant bacteria, including carbapenemase-producing organisms, extended-spectrum β-lactamase-producing bacteria, and AmpC β-lactamase-producing bacteria. We investigate their mechanisms of antimicrobial resistance and conduct molecular epidemiological studies to clarify their emergence and dissemination. In preparation for the emergence of novel resistant organisms, we are also developing rapid and accurate detection methods based on genetic and enzymatic analyses. In addition, we investigate plasmid-mediated gene transfer to elucidate the mechanisms underlying the emergence and spread of antimicrobial-resistant bacteria during antimicrobial therapy. Through these studies, we aim to establish antimicrobial treatment strategies that minimize the development of resistance and to facilitate the discovery of novel antimicrobial agents with unique mechanisms of action, including inhibitors of plasmid transfer. Furthermore, in collaboration with other institutions, we conduct research on parasitic diseases and tick-borne infectious diseases, investigating their epidemiology and pathogenesis using pathogens such as schistosomes, liver flukes, Rickettsia spp., and severe fever with thrombocytopenia syndrome virus. We are also engaged in the development of diagnostic methods and vaccines for these infectious diseases.
