WebSummary: High-affinity iron acquisition is mediated by siderophore-dependent pathways in the majority of pathogenic and nonpathogenic bacteria and fungi. Considerable progress has been made in characterizing and understanding mechanisms of siderophore synthesis, secretion, iron scavenging, and siderophore-delivered iron uptake and its release. WebApr 2, 2024 · Iron acquisition mechanisms The bulk of iron in the body is found in intracellular complexes; however, the amount of free ionic iron is insufficient to support the growth of bacteria [ 62 ]. Pathogenic bacteria have developed several mechanisms to acquire iron from the microenvironments [ 70 ].

WebIn urinary tract infection, available iron is limited, and iron acquisition by bacteria is essential. Furthermore, multiple iron acquisition systems showed different roles in infection, so the redundancy is important for successful infection . Therefore, the results in this study with the C. elegans model is consistent with UTIs in mammal.
