Abstract:
Clostridioides difficile is a kind of opportunistic pathogen ubiquitous in human intestinal tracts. It can induce intestinal inflammation by releasing its unique toxins when the body has dysbacteriosis due to various triggers, causing patients to experience a variety of clinical symptoms ranging from simple diarrhea to fatal septic shock. In recent years, the BI/NAP1/027 strain of Clostridioidesdifficile has been detected in stool samples of patients from medical institutions all around China. This kind of strain can produce higher levels of toxins and spores that are more difficult to eradicate. More importantly, the strain will pose tremendous threats and challenges to global public health security once it spreads. In this paper, the epidemiological characteristics, virulence, pathogenic mechanisms, molecular diagnostic techniques and the treatment methods of hypervirulent Clostridioides difficile strain BI/NAP1/027 were summarized based on the existing research results and case reports at home and abroad. The possible future research hotspots and endeavors in the field have also been suggested. This article aimed to make a comprehensive understanding of hypervirulent Clostridioides difficile strain BI/NAP1/027, and to provide a theoretical basis for more in-depth analysis of its pathogenic mechanism and more scientific formulation of its prevention and treatment plans in the future.
