Candida auris is an urgent public health threat characterized by high drug-resistant rates and rapid spread in healthcare settings worldwide. As part of the C. auris response, molecular surveillance has helped public health officials track the global spread and investigate local outbreaks. Here, we describe whole-genome sequencing analysis methods used for routine C. auris molecular surveillance in the United States; methods include reference selection, reference preparation, quality assessment and control of sequencing reads, read alignment, and single-nucleotide polymorphism calling and filtration. We also describe the newly developed pipeline MycoSNP, a portable workflow for performing whole-genome sequencing analysis of fungal organisms including C. auris.
耳念珠菌是一种紧急的公共卫生威胁,其特点是耐药率高,在全球医疗保健环境中传播迅速。作为耳念珠菌应对措施的一部分,分子监测有助于公共卫生官员跟踪全球传播情况并调查当地疫情。在这里,我们描述了在美国进行常规耳念珠菌分子监测所使用的全基因组测序分析方法;这些方法包括参考选择、参考准备、测序读段的质量评估和控制、读段比对以及单核苷酸多态性的调用和过滤。我们还描述了新开发的 MycoSNP 管道,这是一个用于对真菌生物(包括耳念珠菌)进行全基因组测序分析的便携式工作流程。
