Antibiotic susceptibility testing revealed a low resistance rate to tigecycline (2.13%). Analysis of CRE resistance genes demonstrated that blaKPC accounted for 93.15% of CRKP isolates (68\/73), while blaNDM was present in 90.48% of CREC isolates (19\/21). In the homology analysis, CRKP isolates were divided into five clusters with C<jats:sub>KP<\/jats:sub> type representing the majority at 80.82% prevalence (59\/73). Similarly, CREC could be classified into four clusters with A<jats:sub>EC<\/jats:sub> type being predominant at 80.95% among the isolated strains (17\/21). The detection of CRE strains involved multiple departments in two separate wards of this hospital, located approximately 28\u2009km from each other.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>CRE infection in this hospital has high homology and wide distribution; it is necessary to strengthen prevention and control measures to control CRE nosocomial infection spread.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jcla.70073","type":"journal-article","created":{"date-parts":[[2025,7,3]],"date-time":"2025-07-03T08:25:10Z","timestamp":1751531110000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Drug Resistance and Epidemiological Analysis of Carbapenem\u2010Resistant <i>Enterobacteriaceae<\/i> in a Brain and Psychiatric Hospital of South China"],"prefix":"10.1002","volume":"39","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8738-0111","authenticated-orcid":false,"given":"Lei","family":"Yue","sequence":"first","affiliation":[{"name":"Clinical Laboratory The Affiliated Brain Hospital, Guangzhou Medical University  Guangzhou Guangdong People's Republic of China"},{"name":"Key Laboratory of Neurogenetics and Channelopathies of Guangdong Province and the Ministry of Education of China Guangzhou Medical University  Guangzhou Guangdong People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiumei","family":"Zhu","sequence":"additional","affiliation":[{"name":"Clinical Laboratory The Affiliated Brain Hospital, Guangzhou Medical University  Guangzhou Guangdong People's Republic of China"},{"name":"Key Laboratory of Neurogenetics and Channelopathies of Guangdong Province and the Ministry of Education of China Guangzhou Medical University  Guangzhou Guangdong People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuyan","family":"Kuang","sequence":"additional","affiliation":[{"name":"Clinical Laboratory The Affiliated Brain Hospital, Guangzhou Medical University  Guangzhou Guangdong People's Republic of China"},{"name":"Key Laboratory of Neurogenetics and Channelopathies of Guangdong Province and the Ministry of Education of China Guangzhou Medical University  Guangzhou Guangdong People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yulong","family":"Lin","sequence":"additional","affiliation":[{"name":"Clinical Laboratory The Affiliated Brain Hospital, Guangzhou Medical University  Guangzhou Guangdong People's Republic of China"},{"name":"Key Laboratory of Neurogenetics and Channelopathies of Guangdong Province and the Ministry of Education of China Guangzhou Medical University  Guangzhou Guangdong People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haiying","family":"Liu","sequence":"additional","affiliation":[{"name":"Clinical Laboratory The Affiliated Brain Hospital, Guangzhou Medical University  Guangzhou Guangdong People's Republic of China"},{"name":"Key Laboratory of Neurogenetics and Channelopathies of Guangdong Province and the Ministry of Education of China Guangzhou Medical University  Guangzhou Guangdong People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,7,3]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10096-021-04296-1"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.micres.2022.127249"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1914433"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/cid\/ciy642"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.3390\/antibiotics9080514"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.3389\/fmicb.2021.750662"},{"key":"e_1_2_9_8_1","unstructured":"http:\/\/www.chinets.com\/Data\/GermYear. 02\/29\/2024.
