Iron is an oxidant as well as a nutrient for almost all organisms. A proper balance of this essential nutrient is vital for good health. Its deficiency can lead to many physiological and metabolic disorders while excessive iron in specific tissues of the host (iron loading) promotes infection and other health issues. Iron can also increase disease risk by functioning as a readily available essential nutrient for invading microbial cells (which is essential for their survival and replication).The ability of pathogens to obtain iron from transferrins, ferritin ,hemoglobin and other iron containing proteins of their hosts is crucial for their survival or death. Sequestration of iron is a mechanism to control microbial proliferation and virulence. This paper reviews the iron uptake systems of a variety of organisms and discusses their role in infection.
