We report a hospital outbreak caused by that occurred in 16 patients admitted to intensive care units in Elazığ, Türkiye, between 19 March and 23 April 2024.
The outbreak investigation was initiated on 23 March 2024, four days after was detected in four different patients. Environmental samples were collected from various parts of the hospital to find the source of the outbreak. Arbitrarily Primed Polymerase Chain Reaction (AP-PCR) was performed to determine the genetic relationship between environmental and patient samples.
In total, 16 of 18 isolates were obtained from tracheal aspirate culture. A total of 10 of 16 patients developed hospital-acquired pneumonia due to . Among the environmental cultures in the intensive care units, only the respirator bacterial filter grew. The isolate obtained here was in the same cluster as the isolate obtained from patient samples, resulting in a dominant clustering rate of 94.4%.
Improper and inappropriate use of respirators and equipment can lead to outbreaks. Early detection of the outbreak, identification of the source, and taking appropriate measures quickly to contain the outbreak are key.
我们报告了2024年3月19日至4月23日期间在土耳其埃拉泽的重症监护病房收治的16例患者中由[未提及的病原体]引起的医院感染暴发。
2024年3月23日，在4例不同患者中检测到[未提及的病原体]4天后，启动了暴发调查。从医院各个部位采集环境样本以寻找暴发源。采用任意引物聚合酶链反应（AP-PCR）来确定环境样本和患者样本之间的遗传关系。
总共18份[未提及的病原体]分离株中有16份来自气管吸出物培养。16例患者中有10例因[未提及的病原体]患上医院获得性肺炎。在重症监护病房的环境培养物中，只有呼吸机细菌过滤器培养出细菌。此处获得的分离株与从患者样本中获得的分离株属于同一聚类，聚类率高达94.4%。
呼吸器和设备的不当使用会导致感染暴发。早期发现暴发、确定源头并迅速采取适当措施控制暴发是关键。
