Cutibacterium acnes is a Gram-positive bacterium commonly found on human skin, particularly in sebaceous areas. While it is typically considered a commensal, specific strain types based on single locus sequence typing (SLST) have been associated with pathogenic conditions or healthy skin. Recently, SLST D1 strains, part of phylotype IA1, have received attention for their potential benefits related to skin health. However, their genetic characteristics remain underexplored. Therefore, the whole genome of C. acnes CN6, an SLST D1 strain isolated from the facial skin of a healthy individual, was sequenced to expand the understanding of SLST D1 strains and identify genomic features that may support skin health.
The whole genome sequencing of C. acnes CN6 was conducted using MinION reads based on de novo assembly, revealing a single circular complete chromosome. With the length of 2,550,458 bp and G + C content of 60.04%, the genome contains 2,492 genes, including 2,433 CDSs, 9 rRNAs, 46 tRNAs, 4 ncRNAs, and 134 pseudo genes. Previously predicted virulence proteins of C. ances were detected in the genome. Genome comparation with 200 C. acnes strains isolated from healthy facial skin revealed SLST D1 strain-specific genes and a unique variant of the znuC gene in D1 strains.
痤疮丙酸杆菌是一种常见于人体皮肤的革兰氏阳性细菌,尤其存在于皮脂丰富的区域。虽然它通常被认为是一种共生菌,但基于单基因座序列分型(SLST)的特定菌株类型与致病条件或健康皮肤有关。最近,SLST D1 菌株(IA1 型的一部分)因其与皮肤健康相关的潜在益处而受到关注。然而,其遗传特征仍未得到充分探索。因此,对从健康个体面部皮肤分离出的 SLST D1 菌株 CN6 的全基因组进行了测序,以扩展对 SLST D1 菌株的认识,并鉴定可能支持皮肤健康的基因组特征。
使用 MinION reads 基于从头组装对 CN6 进行了全基因组测序,揭示了一个单一的圆形完整染色体。该基因组长度为 2,550,458 bp,GC 含量为 60.04%,包含 2,492 个基因,包括 2,433 个 CDS、9 个 rRNA、46 个 tRNA、4 个 ncRNA 和 134 个假基因。在基因组中检测到先前预测的痤疮丙酸杆菌的毒力蛋白。与从健康面部皮肤分离出的 200 株痤疮丙酸杆菌进行基因组比较,揭示了 SLST D1 菌株特有的基因和 D1 菌株中 znuC 基因的独特变体。
