a recently recognized, often multidrug-resistant yeast, has become a significant fungal pathogen due to its ability to cause invasive infections and outbreaks in healthcare facilities which have been difficult to control and treat. The extraordinary abilities of to easily contaminate the environment around colonized patients and persist for long periods have recently resulted in major outbreaks in many countries. resists elimination by robust cleaning and other decontamination procedures, likely due to the formation of 'dry' biofilms. Susceptible hospitalized patients, particularly those with multiple comorbidities in intensive care settings, acquire rather easily from close contact with -infected patients, their environment, or the equipment used on colonized patients, often with fatal consequences. This review highlights the lessons learned from recent studies on the epidemiology, diagnosis, pathogenesis, susceptibility, and molecular basis of resistance to antifungal drugs and infection control measures to combat the spread of infections in healthcare facilities. Particular emphasis is given to interventions aiming to prevent new infections in healthcare facilities, including the screening of susceptible patients for colonization; the cleaning and decontamination of the environment, equipment, and colonized patients; and successful approaches to identify and treat infected patients, particularly during outbreaks.
一种最近才被认识到的、通常具有多重耐药性的酵母菌,由于其能够在医疗机构中引起侵袭性感染和疫情暴发,且难以控制和治疗,已成为一种重要的真菌病原体。它具有轻易污染定植患者周围环境并长期存活的非凡能力,最近在许多国家导致了重大疫情暴发。它能抵抗强力清洁和其他去污程序的清除,这可能是由于形成了“干燥”生物膜。易感的住院患者,尤其是重症监护病房中患有多种合并症的患者,通过与感染该菌的患者、其周围环境或用于定植患者的设备密切接触,很容易感染该菌,且往往会导致致命后果。本综述重点介绍了从近期关于该菌的流行病学、诊断、发病机制、药敏性以及抗真菌药物耐药性的分子基础和感染控制措施等研究中吸取的经验教训,以对抗其在医疗机构中的传播。特别强调了旨在预防医疗机构中新发感染的干预措施,包括对易感患者进行定植筛查;对环境、设备和定植患者进行清洁和去污;以及在疫情暴发期间识别和治疗感染患者的成功方法。
