The application of chemical disinfectants is an effective infection control strategy to prevent the spread of CRKP in hospital environments. However, bacteria have shown reduced sensitivity to clinical disinfectants in recent years. Furthermore, bacteria can acquire antibiotic resistance due to the induction of disinfectants, posing a considerable challenge to hospital infection prevention and control. This study collected 68 CRKP strains from the Fifth Affiliated Hospital of Xinjiang Medical University in China from 2023 to 2024. These strains were isolated from the sputum, urine, and whole blood samples of patients diagnosed with CRKP infection. Antibiotic susceptibility tests were performed on CRKP strains. Concurrently, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of disinfectants (benzalkonium bromide, 1% iodophor disinfectant, alcohol, and chlorine-containing disinfectant) against the test isolates were determined by the broth microdilution method. The efflux pump genes (cepA, qacE, qacE\u03941, qacE\u03941-SUL1, oqxA, and oqxB) were detected using polymerase chain reaction. The results showed that 21 out of the 68 CRKP strains exhibited extensive drug resistance, whereas 47 were nonextensively drug-resistant. The MIC value for benzalkonium bromide disinfectants displayed statistically significant differences (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    &lt; 0.05) between extensively drug-resistant (XDR) and non-XDR strains. Additionally, the MBC values for benzalkonium bromide disinfectants and 1% iodophor disinfectants displayed statistically significant differences (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    &lt; 0.05) between XDR and non-XDR strains. The detection rates for the efflux pump genes were as follows: cepA 52.9%, qacE 39.7%, qacE\u03941 35.2%, qacE\u03941-SUL1 52.9%, oqxA 30.8%, and oqxB 32.3%. The detection rate of the qacE\u03941-SUL1 gene in XDR CRKP strains was significantly higher than in non-XDR CRKP strains (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    &lt; 0.05). This indicates a potential link between CRKP bacterial disinfectant efflux pump genes and CRKP bacterial resistance patterns. Ongoing monitoring of the declining sensitivity of XDR strains against disinfectants is essential for the effective control and prevention of superbug.\n                  <\/jats:p>","DOI":"10.1089\/mdr.2024.0089","type":"journal-article","created":{"date-parts":[[2024,8,21]],"date-time":"2024-08-21T20:39:09Z","timestamp":1724272749000},"page":"407-414","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["Determining the Disinfectants Resistance Genes and the Susceptibility to Common Disinfectants of Extensively Drug-Resistant Carbapenem-Resistant\n                    <i>Klebsiella pneumoniae<\/i>\n                    Strains at a Tertiary Hospital in China"],"prefix":"10.1177","volume":"30","author":[{"given":"Kexin","family":"Zhao","sequence":"first","affiliation":[{"name":"School of Nursing, Xinjiang Medical University, Urumqi, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liang","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, The Fifth Affiliated Hospital of Xinjiang Medical University, Urumqi, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinglan","family":"Deng","sequence":"additional","affiliation":[{"name":"School of Nursing, Xinjiang Medical University, Urumqi, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiuxia","family":"Zuo","sequence":"additional","affiliation":[{"name":"School of Nursing, Xinjiang Medical University, Urumqi, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maimaiti","family":"Adila","sequence":"additional","affiliation":[{"name":"School of Nursing, Xinjiang Medical University, Urumqi, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiao","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Nursing, Xinjiang Medical University, Urumqi, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhe","family":"Dai","sequence":"additional","affiliation":[{"name":"Fifth School of Clinical Medicine, Xinjiang Medical University, Urumqi, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ping","family":"Tian","sequence":"additional","affiliation":[{"name":"Infection Management Department, The Fifth Affiliated Hospital of Xinjiang Medical University, Urumqi, China."},{"name":"Health Care Research Center for Xinjiang Regional population, Urumqi, China."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,10,4]]},"reference":[{"issue":"9","key":"e_1_3_8_2_2","first-page":"165","article-title":"Vital signs: Carbapenem-resistant enterobacteriaceae","volume":"62","year":"2013","unstructured":"Vital signs: Carbapenem-resistant enterobacteriaceae.
