产气荚膜梭菌是一种快速生长的病原体,已知它能分泌大量剧毒毒素,在过去的一个世纪里,它一直与动物和人类的肠道疾病有关。基因组分析和实验系统的最新进展使重新访问这种临床和兽医学上重要的病原体变得及时。这篇综述将总结我们对该肠道病原体的基因组学和毒力相关因素,包括抗菌潜力和分泌毒素的了解,以及它在几种重要的人和动物相关肠道疾病发病机制中的最新临床流行病学和生物学作用,包括早产儿坏死性小肠结肠炎。最后,我们强调了与产气荚膜梭菌介导的感染相关的一些重要的悬而未决的问题,并对未来的研究方向提出了建议。
Clostridium perfringens, a rapid-growing pathogen known to secrete an arsenal of >20 virulent toxins, has been associated with intestinal diseases in both animals and humans throughout the past century. Recent advances in genomic analysis and experimental systems make it timely to re-visit this clinically and veterinary important pathogen. This Review will summarise our understanding of the genomics and virulence-linked factors, including antimicrobial potentials and secreted toxins of this gut pathogen, and then its up-to-date clinical epidemiology and biological role in the pathogenesis of several important human and animal-associated intestinal diseases, including pre-term necrotising enterocolitis. Finally, we highlight some of the important unresolved questions in relation to C. perfringens-mediated infections, and implications for future research directions.
