The Role of Iron in Bacterial Virulence
Úloha železa v bakteriálnej virulencii
V článku sú zhrnuté údaje o úlohe železa v interakcii baktéria – hostiteľ v súvislosti s virulenciou.Pozornosť sa venuje získavaniu železa baktériami od hostiteľa prostredníctvom nasledujúcichmechanizmov. Tieto zahrňujú získavanie železa z degradovaných produktov hemoglobínu (hém,hemín), priamo z transferínu a laktoferínu viažúceho železo, ako aj nepriamo z vyššie uvedenýchproduktov pomocou siderofórov a tiež aj z ďalších intrabunkových zdrojov (feritín). Diskutuje sa ajregulácia vychytávania železa.
Klíčová slova:
železo – baktéria – hostiteľ – virulencia.

Overview
Data on the role of iron in host-bacterium interaction in relation to virulence are summarized.Attention is focused on host iron acquisition pathways in bacteria. Host iron can be acquired byseveral mechanisms, e.g. from hemoglobin degradation products such as heme and hemin, directlyfrom ferrated transferrin and lactoferrin, indirectly from iron binding proteins by the productionof siderophores and from intracellular iron stores (ferritin). Regulation of iron uptake is discussed.
Key words:
iron – bacteria – host – virulence.
