A defense strategy against a bacterial infection is the so-called nutritional immunity. This involves limiting the availability of iron for pathogens (12), because Iron is an essential nutrient for pathogenic bacteria (3).
In response to limiting the availability of iron for pathogens, bacteria have developed sophisticated iron uptake systems to overcome this limitation. These systems include:
These iron uptake systems are crucial for the survival of bacteria and are closely related to virulence and […
