Candida albicans is the predominant cause of vulvovaginal candidiasis (VVC). Little is known regarding the genetic diversity of Candida spp. in the vagina or the microvariations in strains over time that may contribute to the development of VVC. This study reports the draft genome sequences of four C. albicans and one C. glabrata strains isolated from women with VVC. An SNP-based whole-genome phylogeny indicates that these isolates are closely related; however, phylogenetic distances between them suggest that there may be genetic adaptations driven by unique host environments. These sequences will facilitate further comparative analyses and ultimately improve our understanding of genetic variation in isolates of Candida spp. that are associated with VVC.
白色念珠菌是外阴阴道念珠菌病(VVC)的主要病原体。目前对于阴道内念珠菌属的遗传多样性以及可能导致 VVC 的菌株随时间的微小变化知之甚少。本研究报告了从患有 VVC 的女性中分离出的 4 株白色念珠菌和 1 株光滑念珠菌的基因组序列草案。基于 SNP 的全基因组系统发育分析表明,这些分离株密切相关;然而,它们之间的系统发育距离表明,可能存在由独特的宿主环境驱动的遗传适应性。这些序列将有助于进一步的比较分析,并最终提高我们对与 VVC 相关的念珠菌属分离株遗传变异的理解。
