, a fastidious anaerobic spirochete, is one of the main pathogens involved in the development and progression of bovine digital dermatitis (BDD), a lameness-causing hoof infection in cattle. Here, the complete genome sequencing of GNW45 isolated from a dairy cow infected with BDD, was presented. Libraries for long and short reads were sequenced using PacBioRSII and Illimuna HiSeqXTen platforms, respectively. assembly was done using the long reads, producing a circular contig, by which the short reads were aligned to generate a more accurate genome sequence. The genome has a total size of 3,077,465 base pairs, with 36.84% guanine-cytosine content. A total of 2,749 protein-coding sequences, seven ribosomal RNA's, and 45 transfer RNA's were annotated. Functional analysis revealed genes associated with pathogenicity and survivability in the complex pathobiome of BDD. This study provided novel insights into the survival and pathogenic mechanisms of GNW45.
,一种苛求性厌氧螺旋体,是参与牛趾间皮炎(BDD)发生和发展的主要病原体之一,BDD是一种导致牛跛行的蹄部感染。在此,展示了从感染BDD的奶牛中分离出的GNW45的全基因组测序。分别使用PacBioRSII和Illimuna HiSeqXTen平台对长读长和短读长文库进行测序。使用长读长进行组装,产生一个环状重叠群,通过该重叠群将短读长进行比对以生成更准确的基因组序列。该基因组总大小为3,077,465个碱基对,鸟嘌呤 - 胞嘧啶含量为36.84%。共注释了2,749个蛋白质编码序列、7个核糖体RNA和45个转运RNA。功能分析揭示了与BDD复杂病理生物群落中的致病性和生存能力相关的基因。本研究为GNW45的生存和致病机制提供了新的见解。
