摘要
Clostridioides difficile (CD) is one of the most common pathogens causing health-care-associated infectious diarrhea and is listed by the U.S. Centers for Disease Control and Prevention as an urgent antibiotic resistance (AR) threat. Many resistance genes can be transferred between different CD strains present in the clinical setting, community, and environment. The antimicrobial resistance (AMR) of CD continues to evolve with the emergence and acquisition of new drug resistance mechanisms. CD has developed diverse drug resistance mechanisms, such as drug alteration, modification of the target site, and extrusion of drugs via efflux pumps. Researches have provided comprehensive knowledge about resistance mechanisms of macrolides and quinolones in CD. However, the mechanisms of resistance for metronidazole, vancomycin, and other therapeutic antibiotics against Clostridioides difficile infection (CDI) are only beginning to be elucidated. Some previously unfound mechanisms, such as plasmid-mediated drug resistance in CD, may also play an important role. In this review, we summarize the research progress on drug resistance mechanisms of CD with antimicrobial drugs already used clinically, such as metronidazole, vancomycin, and fidaxomicin, thereby providing the references for the clinical treatment and prevention of CDI, as well as the development of new antibacterial drugs and detection kits for drug resistant bacteria.
