%X While the emergence and spread of carbapenem-resistant Enterobacteriaceae (CRE) and related infections pose serious threats to global public health, the epidemiology and associated risk factors remain poorly understood and vary by geography.<BR>In a case-controlled retrospective study, we examined the prevalence, patient background and risk factors for CRE colonisation and infections, and all patient-derived CRE from January 2015 to January 2017. Isolated carbapenem-susceptible Enterobacteriaceae (CSE) from 2875 enrolled patients were randomly selected during the study.<BR>CRE colonisation and infections detection rates were 47/2875 (1.6%). Respiratory tract specimens were most frequently seen in 20/47 (42.6%) cases. Klebsiella pneumoniae was the main isolate in 35/47 (74.5%) CRE. As for carbapenemase, KPC-2-producing bacteria was most frequently detected in 38/47 (80.9%) Enterobacteriaceae. No underlying conditions (P = 0.004), pulmonary diseases (P = 0.018) and no antibiotics used prior to culture within 30 days (P < 0.001) were statistically significant between the CRE and CSE groups.<BR>Klebsiellapneumoniae was the main isolate of CRE. The blaKPC-2 was the predominant CRE gene. Underlying conditions especially pulmonary diseases and antibiotics used prior to culture within 30 days represented key risk factors for acquisition of CRE.
