Contamination during graft acquisition and transport can lead to DRIs, and the use of antibiotics in preservation fluid (PF) before organ transplantation can reduce the incidence of DRIs. This study was to determine and compare the effectiveness of different PF decontamination regimens to prevent CRGNB related DRIs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Twelve CRGNB strains were chosen to be the targets of decontamination, and a drug concentration gradient was established for each test drug based on the previous clinical research. In addition the standard decontamination procedures were performed to evaluate the antimicrobial effectiveness of polymyxin B (PB), colistin sulfate (CS), colistimethate sodium (CMS) and amikacin (AK) in the 0~4\u00b0C PF, and to explore the antimicrobial effects of CMS after different preprocessing methods.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>PB and CS exhibited significantly better antimicrobial effectiveness against CRGNB than AK and CMS in the 0~4\u00b0C PF, and the antimicrobial effects on CRGNB increased with the increasing concentration of drugs. Notably, CMS after pretreatment (CMS-AP), its antibacterial was significantly enhanced at 4\u00b0C.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The PF decontamination is important in preventing the DRIs caused by CRGNB, and the decontamination regimens based on PB or CS were confirmed effective. Notably, CMS could even achieve a better decontamination effect than PB after a simple and fast pretreatment.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fcimb.2025.1572799","type":"journal-article","created":{"date-parts":[[2025,7,23]],"date-time":"2025-07-23T05:36:42Z","timestamp":1753249002000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Prevention of donation-related infections: investigating the use of antibiotics in the decontamination of preservation fluid for organ transplantation"],"prefix":"10.3389","volume":"15","author":[{"given":"Yazhe","family":"Duan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junhao","family":"Yu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pei","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuhong","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kewen","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanfeng","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuxiang","family":"Wan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kang","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li","family":"Zeng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanhua","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mingxing","family":"Sui","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2025,7,23]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1357","DOI":"10.2147\/IDR.S398930","article-title":"Adverse events and drug resistance in critically ill patients treated with colistimethate sodium: A review of the literature","volume":"16","author":"Ahumada Topete","year":"2023","journal-title":"Infect.
