is a non-fermenting, gram-negative bacteria that has previously been implicated in multiple nosocomial outbreaks through the use of contaminated medical devices and substances. This article reports on an outbreak of infections and colonizations, involving 11 patients from five acute care hospitals in Montréal, Canada.
One sample was not available for testing, but the remaining 10 isolates (91%) were sent for phylogenetic testing. Medical materials and the patients' environments were also sampled and cultured. Samples were tested using pulsed field gel electrophoresis and multilocus sequence typing.
The outbreak was found to be associated with the use of intrinsically contaminated non-sterile ultrasound gel. Relatedness of the gel's and the patients' strains was demonstrated using gel electrophoresis and multilocus sequence typing analyses. The investigation was concluded with a prompt recall of the product, and the outbreak was declared over by the end of October 2021.
Contaminated non-sterile gel caused infections and pseudo-infections in several patients.
是一种非发酵革兰氏阴性菌，此前曾因使用受污染的医疗设备和物质而引发多起医院感染暴发。本文报道了一起感染和定植暴发事件，涉及加拿大蒙特利尔五家急症护理医院的11名患者。
有一份样本无法用于检测，但其余10株分离菌（91%）被送去进行系统发育检测。还对医疗材料和患者的环境进行了采样和培养。样本采用脉冲场凝胶电泳和多位点序列分型进行检测。
发现此次暴发与使用本质上受污染的非无菌超声凝胶有关。通过凝胶电泳和多位点序列分型分析证明了凝胶菌株与患者菌株的相关性。调查以迅速召回该产品告终，疫情于2021年10月底宣布结束。
受污染的非无菌凝胶在数名患者中引起了感染和假感染。
