Bacillus anthracis requires siderophore biosynthesis for growth in macrophages and mouse virulence.

Abstract excerpt

Systemic anthrax infections can be characterized as proceeding in stages, beginning with an early intracellular establishment stage within phagocytes that is followed by extracelluar stages involving massive bacteraemia, sepsis and death.
