Abstract

species are the most prevalent cause of invasive fungal infections, of which is the most common. Translocation across the epithelial barrier into the bloodstream by intestinal-colonizing cells serves as the main source for systemic infections. Understanding the fungal mechanisms behind this process will give valuable insights on how to prevent such infections and keep in the commensal state in patients with predisposing conditions. This review will focus on recent developments in characterizing fungal translocation mechanisms, compare what we know about enteric bacterial pathogens with , and discuss the different proposed hypotheses for how enters and disseminates through the bloodstream immediately following translocation.

摘要

真菌种属是侵袭性真菌感染最常见的原因,其中 是最常见的一种。肠道定植细胞穿过上皮屏障易位进入血液是引发全身感染的主要来源。了解这一过程背后的真菌机制将为如何预防此类感染以及使 在有易感染条件的患者中保持共生状态提供有价值的见解。本文综述重点在于阐述真菌易位机制的最新研究进展,将其与肠道细菌病原体进行比较,并讨论 易位进入血液后立即播散的不同假说。
