Research Article: Genomic Epidemiology and Antimicrobial Resistance Profiles of Clostridioides difficile from Multi-Hospitals in a City in Eastern China
Abstract:
Clostridioides difficile is a leading pathogen that frequently causes hospital infections. About –% of the cases of antibiotic-associated diarrhea and % of Pseudomembranous enteritis cases are caused by C. difficile. C. difficile infection (CDI) is a toxin-mediated disease, and most C. difficile toxigenic strains produce two main toxins, TcdA and TcdB. In addition, some strains additionally produce “binary toxins” (CDT), encoded by the cdtA and cdtB genes. With the outbreak of hypervirulent ribotyping (B/NAP/ST) in Europe and North America, C. difficile has become a major challenge affecting public health and represents a significant burden for global health-care systems. In , C. difficile infected nearly , patients and caused around , deaths in the United States. CDI is also the most frequent hospital-acquired infection in Europe,, and , CDI cases and deaths occur every year, resulting in medical expenses and direct economic losses of about billion Euros. A meta-analysis showed that the incidence rate of hospital infection with CDI in China was %. In , C. difficile ribotyping was detected for the first time on mainland China after which sporadic occurrences of ribotyping were reported. However, outbreaks in hospitals were also reported. Therefore, it is still important to increase focus on the genomic epidemiological surveillance of C. difficile.
