光滑念珠菌是一种机会致病的人类真菌病原体,其发病率在过去二十年中有所增加。尽管它的名字,这种酵母菌只是远亲的模式真菌病原体C。白色念珠菌,更密切相关的酿酒酵母和其他酵母,经历了一个古老的全基因组复制。了解哪些特定的特征使C。glabrata是一个成功的机会致病菌在一个分支的大多数无害的酵母,以及如何比较这些毒力性状在遥远的病原体,如C。白色念珠菌是研究的重点。从进化的角度来看,揭示感染人类的能力如何在不同谱系中出现多个独立的时间,可能会揭示新的疾病机制,并为我们提供预测进化枝中哪些基因组特征可能赋予更高的潜力来发展对人类的毒力的能力。 光滑念珠菌是一种人类机会致病菌;基因组学分析揭示了其毒力的进化路径。
The yeast Candida glabrata is an opportunistic human fungal pathogen whose incidence has increased in the last two decades. Despite its name, this yeast is only distantly related to the model fungal pathogen C. albicans, and more closely related to Saccharomyces cerevisiae and other yeasts that underwent an ancient whole-genome duplication. Understanding what specific traits make C. glabrata a successful opportunistic pathogen within a clade of mostly innocuous yeasts, and how these compare to virulence traits in distant pathogens such as C. albicans is a focus of intense research. From an evolutionary perspective, uncovering how the ability to infect humans has emerged multiple, independent times in different lineages may reveal new disease mechanisms and provide us with the capacity to predict which genomic features in a clade may confer a higher potential to develop virulence against humans. Candida glabrata is an opportunistic human pathogen; genomics analyses have revealed its evolutionary path to virulence.
