Abstract

() is responsible for 80% of human campylobacteriosis and is the leading cause of gastroenteritis globally. The relevant public health risks of are caused by particular virulence genes encompassing its virulome. We analyzed 40,371 publicly available genomes of deposited in the NCBI Pathogen Detection Database, combining their epidemiologic metadata with an in silico bioinformatics analysis to increase our current comprehension of their virulome from a global perspective. The collection presented a virulome composed of 126 identified virulence factors that were grouped in three clusters representing the accessory, the softcore, and the essential core genes according to their prevalence within the genomes. The multilocus sequence type distribution in the genomes was also investigated. An unexpected low prevalence of the full-length flagellin and locus of genomes was revealed, and an essential core virulence gene repertoire prevalent in more than 99.99% of genomes was identified. Altogether, this is a pioneer study regarding that has compiled a significant amount of data about the Multilocus Sequence Type and virulence factors concerning their global prevalence and distribution over this database.

摘要

(某病原体)导致了80%的人类弯曲杆菌病,是全球肠胃炎的主要病因。该病原体的相关公共卫生风险由其毒力组中包含的特定毒力基因引起。我们分析了NCBI病原体检测数据库中存放的40371个该病原体的公开可用基因组,将其流行病学元数据与计算机生物信息学分析相结合,以便从全球角度增强我们目前对其毒力组的理解。该数据集呈现出一个由126个已鉴定毒力因子组成的毒力组,这些毒力因子根据其在基因组中的流行程度分为三个簇,分别代表辅助基因、软核基因和必需核心基因。我们还研究了基因组中的多位点序列类型分布。结果显示该病原体基因组中全长鞭毛蛋白和(另一个基因位点)的意外低流行率,并鉴定出在超过99.99%的基因组中普遍存在的必需核心毒力基因库。总之,这是一项关于该病原体的开创性研究,它收集了大量关于多位点序列类型和毒力因子在该数据库中的全球流行率和分布的数据。
