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.
耳念珠菌是一种致病性酵母菌,常表现出多药耐药性,因此需要特别关注。为了防止其在医疗机构中传播,需要及时发现并正确鉴定这种病原体。本文作者先前开发了一种用于特定检测耳念珠菌的环介导等温扩增检测方法(LAMPAuris)。本报告评估了 LAMPAuris 从五个谱系中鉴定耳念珠菌的能力,并从临床标本中检测耳念珠菌的能力。共对 103 份皮肤拭子样本进行了检测,与基于培养的方法和耳念珠菌特异性 SYBR green qPCR 进行了比较。结果表明,LAMPAuris 检测方法的特异性为 97%至 100%,敏感性为 66%至 86%。较低的敏感性可能归因于样本储存时间延长导致的 DNA 降解。总之,LAMPAuris 被证明是一种快速可靠的方法,可用于鉴定耳念珠菌并检测临床标本中的耳念珠菌。新鲜标本应能保证更好的产量和更高的敏感性。
