Abstract

Candida auris is a pathogenic yeast frequently exhibiting multidrug resistance and thus warrants special attention. The prompt detection and proper identification of this organism are needed to prevent its spread in healthcare facilities. The authors of this paper had previously developed LAMPAuris, a loop-mediated isothermal amplification assay, for the specific detection of C. auris. LAMPAuris is evaluated in this report for its ability to identify C. auris from five clades and to detect it from clinical specimens. A total of 103 skin swab samples were tested in comparison with a culture-based method and C. auris-specific SYBR green qPCR. The results show that the LAMPAuris assay had specificities ranging from 97 to 100% and sensitivities ranging from 66 to 86%. The lower sensitivity could be attributed to DNA degradation caused by the prolonged storage of the samples. In conclusion, LAMPAuris proved to be a rapid and reliable method for identifying C. auris and for detecting it in clinical specimens. Fresh specimens should ensure better yield and higher sensitivities.

评估 LAMPAuris 用于快速检测临床样本中的念珠菌。

白色念珠菌是一种致病性酵母菌，经常表现出多重耐药性，因此值得特别关注。需要及时检测和正确识别这种微生物，以防止其在医疗机构中传播。本文作者之前开发了一种用于特异性检测 C. auris 的环介导等温扩增检测法 LAMPAuris。本报告对 LAMPAuris 的能力进行了评估，以确定它能从五个支系中识别出阿氏杆菌，并能从临床样本中检测出阿氏杆菌。共检测了 103 份皮肤拭子样本，并与基于培养的方法和 C. auris 特异性 SYBR green qPCR 进行了比较。结果显示，LAMPAuris 检测法的特异性在 97% 到 100% 之间，灵敏度在 66% 到 86% 之间。灵敏度较低的原因可能是样本长期储存导致 DNA 降解。总之，LAMPAuris 被证明是一种快速、可靠的方法，可用于鉴定和检测临床标本中的弓形虫。新鲜标本可确保更高的检出率和灵敏度。

期刊介绍： Mycopathologia is an official journal of the International Union of Microbiological Societies (IUMS). Mycopathologia was founded in 1938 with the mission to ‘diffuse the understanding of fungal diseases in man and animals among mycologists’. Many of the milestones discoveries in the field of medical mycology have been communicated through the pages of this journal. Mycopathologia covers a diverse, interdisciplinary range of topics that is unique in breadth and depth. The journal publishes peer-reviewed, original articles highlighting important developments concerning medically important fungi and fungal diseases. The journal highlights important developments in fungal systematics and taxonomy, laboratory diagnosis of fungal infections, antifungal drugs, clinical presentation and treatment, and epidemiology of fungal diseases globally. Timely opinion articles, mini-reviews, and other communications are usually invited at the discretion of the editorial board. Unique case reports highlighting unprecedented progress in the diagnosis and treatment of fungal infections, are published in every issue of the journal. MycopathologiaIMAGE is another regular feature for a brief clinical report of potential interest to a mixed audience of physicians and laboratory scientists. MycopathologiaGENOME is designed for the rapid publication of new genomes of human and animal pathogenic fungi using a checklist-based, standardized format.
