In healthcare settings, spp. cause invasive disease with high mortality. The overwhelming majority of cases are associated with the use of critically-needed medical devices, such as vascular catheters. On the surface of these indwelling materials, forms resilient, adherent biofilm communities. A hallmark characteristic of this process is the production of an extracellular matrix, which promotes fungal adhesion and provides protection from external threats. In this review, we highlight the medical relevance of device-associated biofilms and draw attention to the process of -biofilm-matrix production. We provide an update on the current understanding of how biofilm extracellular matrix contributes to pathogenicity, particularly through its roles in the promoting antifungal drug tolerance and immune evasion.
在医疗环境中,某些物种会引发具有高死亡率的侵袭性疾病。绝大多数病例与使用急需的医疗设备有关,如血管导管。在这些植入材料的表面,该物种形成有弹性的、附着性的生物膜群落。这个过程的一个标志性特征是细胞外基质的产生,它促进真菌黏附并提供抵御外部威胁的保护。在这篇综述中,我们强调与设备相关的该物种生物膜的医学相关性,并提请注意该物种生物膜基质的产生过程。我们提供了关于目前对生物膜细胞外基质如何促成致病性的理解的最新情况,特别是通过其在促进抗真菌药物耐受性和免疫逃避中的作用。
