简要总结
In this study, metagenomic sequencing (10G) results of stool samples from health care workers in ICU and non-medical professionals were compared to observe whether there are significant differences in community diversity, structure and function of intestinal microbiota and whether there are drug resistance genes carried by intestinal microbes, so as to determine whether long-term exposure to multi-pathogen environment in ICU has an impact on intestinal microbiota.
详细描述
The infection rate of multidrug-resistant bacteria in critically ill patients in intensive care unit (ICU) is high, resulting in high mortality, prolonged hospitalization, and becoming a source of pathogen transmission. The front-line medical staff engaged in ICU are constantly in contact with patients and exposed to the intensive care unit (ICU) environment, and this high-risk contact and exposure makes many pathogenic microorganisms and their drug-resistance genes become part of the intestinal microbiota of ICU medical staff and are carried. So far, there have been no previous reports on the characteristics of intestinal microbiome and the drug resistance genes carried by ICU staff. Therefore, in this study, metagenomic sequencing (10G) results of stool samples from medical staff and non-medical professionals in ICU were compared to observe whether there are significant differences in community diversity, structure and function of intestinal microbiota and whether there are drug resistance genes carried by intestinal microbes, so as to determine whether long-term exposure to multi-pathogen environment in ICU has an impact on intestinal microbiota.
