Abstract

This review gathers recent information about genomic and transcriptomic studies in the genus, exploring, for example, prediction of pathogenicity islands and stress response in different pathogenic and non-pathogenic species. In addition, is described several phylogeny studies to , exploring since the identification of species until biological speciation in one species belonging to the genus . Important concepts associated with virulence highlighting the role of Pld protein and Tox gene. The adhesion, characteristic of virulence factor, was described using the sortase mechanism that is associated to anchorage to the cell wall. In addition, survival inside the host cell and some diseases, were too addressed for pathogenic corynebacteria, while important biochemical pathways and biotechnological applications retain the focus of this review for non-pathogenic corynebacteria. Concluding, this review broadly explores characteristics in genus showing to have strong relevance inside the medical, veterinary, and biotechnology field.

摘要

本综述收集了该属基因组和转录组研究的最新信息,例如探索不同致病和非致病物种中致病岛的预测及应激反应。此外,还描述了多项系统发育研究,从该属物种的鉴定到一个物种的生物物种形成进行探索。强调了与毒力相关的重要概念,突出了Pld蛋白和Tox基因的作用。利用与细胞壁锚定相关的分选酶机制描述了作为毒力因子特征的黏附作用。此外,还探讨了致病棒状杆菌在宿主细胞内的存活情况及一些疾病,而重要的生化途径和生物技术应用仍是本综述对非致病棒状杆菌的关注重点。总之,本综述广泛探索了该属的特征,显示出在医学、兽医和生物技术领域具有很强的相关性。
