Urinary tract infection (UTI) is a global health issue that imposes a substantial burden on healthcare systems. Women are disproportionately affected by UTI, with >60% of women experiencing at least one UTI in their lifetime. UTIs can recur, particularly in postmenopausal women, leading to diminished quality of life and potentially life-threatening complications. Understanding how pathogens colonize and survive in the urinary tract is necessary to identify new therapeutic targets that are urgently needed due to rising rates of antimicrobial resistance. How , a bacterium commonly associated with UTI, adapts to the urinary tract remains understudied. Here, we generated a collection of high-quality closed genome assemblies of clinical urinary isolated from the urine of postmenopausal women that we used alongside detailed clinical metadata to perform a robust comparative genomic investigation of genetic factors that may be involved in survival in the urinary tract.
尿路感染(UTI)是一个全球性的健康问题,给医疗系统带来了巨大的负担。女性受 UTI 的影响不成比例,超过 60%的女性一生中至少会经历一次 UTI。UTIs 会反复发作,特别是在绝经后妇女中,导致生活质量下降,并可能出现危及生命的并发症。了解病原体如何在尿路中定植和存活对于确定新的治疗靶点是必要的,因为抗生素耐药性的上升导致了对这些靶点的迫切需求。如何,一种通常与 UTI 相关的细菌,适应尿路的机制仍在研究之中。在这里,我们从绝经后妇女的尿液中分离出了一组高质量的临床尿分离株的封闭基因组组装,我们结合详细的临床元数据,对可能涉及尿路生存的遗传因素进行了稳健的比较基因组研究。
