In this study, 238 rectal screening swabs for carbapenem-resistant Enterobacteriaceae (CRE) were compared using chromID CARBA plates and the CDC reference method. Direct inoculation of chromID CARBA plates only identified 53% of CRE, whereas meropenem broth enrichment increased the positive agreement to 88% and identified additional cases of CRE. Additionally, the chromID CARBA method allowed for faster results and decreased the number of colonies further tested.
在本研究中，使用chromID CARBA平板和美国疾病控制与预防中心（CDC）参考方法对238份用于检测耐碳青霉烯类肠杆菌科细菌（CRE）的直肠筛查拭子进行了比较。直接接种chromID CARBA平板仅鉴定出53%的CRE，而美罗培南肉汤增菌使阳性一致性提高到88%，并鉴定出更多CRE病例。此外，chromID CARBA方法能更快得出结果，并减少了进一步检测的菌落数量。
