研究目的:

1.主要目的 调查本研究纳入的目标菌株,即碳青霉烯耐药肠杆菌科细菌(CRE)和碳青霉烯耐药鲍曼不动杆菌(CRAB)在医院内的环境储菌源。 明确环境储菌源与传染病患者继发相应耐药菌感染的关系。 2.次要目的 引入早期预防理念,结合环境储菌源查找结果,制定集束化防控措施。  

Objectives of Study:

1. Main purpose Investigate the environmental storage sources of the target strains included in this study, namely carbapenem resistant Enterobacteriaceae (CRE) and carbapenem resistant Acinetobacter baumannii (CRAB), in hospitals. Clarify the relationship between environmental bacterial storage sources and secondary drug-resistant bacterial infections in infectious disease patients. 2. Secondary purpose Introduce the concept of early prevention and develop bundled prevention and control measures based on the results of environmental bacterial source search.
