Abstract

subsp. () is a common subspecies in reptiles and has been implicated as a source of serious and life-threatening diseases in humans. Although occurrence and significance of infections have been extensively studied, the genetic features of have remained unknown due to a lack of available high-quality genome sequences. We obtained the complete genome sequence of 45:g,z51:- strain 20-369 isolated from multiple abdominal abscesses of an African fat-tailed gecko () using Nanopore and Illumina sequencing technologies and generated the 4.65Mbp complete genome sequence of the str. 20-369. We annotated and analyzed the genome sequence with the aim to gain a deeper understanding of the genome characteristics associated with its pathogenicity. Overall, this study found several interesting genomic features such as pseudogene formation, virulence gene profile, and novel genomic islands. This study provides basis for an understanding possible genetic mechanism underlying pathogenicity of 45:g,z51:- as well as a high-quality genome reference for future comparison studies.

摘要

亚种()是爬行动物中常见的亚种,被认为是人类严重和危及生命疾病的来源。尽管对感染的发生情况和重要性进行了广泛研究,但由于缺乏可用的高质量基因组序列,其遗传特征仍然未知。我们使用纳米孔和Illumina测序技术,从一只非洲肥尾壁虎()的多个腹部脓肿中分离出45:g,z51:-菌株20-369,并获得了其完整的基因组序列,生成了4.65Mbp的str. 20-369完整基因组序列。我们对基因组序列进行注释和分析,旨在更深入地了解与其致病性相关的基因组特征。总体而言,本研究发现了几个有趣的基因组特征,如假基因形成、毒力基因谱和新的基因组岛。本研究为理解45:g,z51:-致病性可能的遗传机制提供了基础,也为未来的比较研究提供了高质量的基因组参考。
