It occurs when there is a negative balance between iron requirements, absorption, and losses. In ...
Red meat is an excellent source of heme iron, while the less bioavailable nonheme form is found in large amounts in milk products and vegetables. For this reason, consumers of meat have a better iron status than vegetarians and vegans. Heme iron found in muscle protein should be supplied ...
Heme iron was very low in clams (<0.4mg/RA) relative to beef (2.3±0.2mg/RA). One serving (56g) of live or minced clams provided less than one-third as much bioavailable iron as 9.8mg FeSO4; whereas one serving of whole baby clams provided the same amount of bioavailable iron as ...
Iron is required for a wide variety of biological functions but can be a limiting nutrient in most bacterial niches. Many bacteria can utilize heme as an alternative source of nutritional iron. However heme degrading enzymes called heme oxygenases (HOs) have been identified in only a few bacteri...

However, we find that mutants lacking the permease eventually do cause disease, thus revealing that additional iron sources such as heme and other uptake mechanisms are available to C. neoformans. Finally, we noted that the permease mutant showed particularly poor growth in the brains of infected ...
for iron utilization from transferrin but not heme during growth in laboratory culture. This result when combined with the observed slow growth of the permease mutant during the experimental infections implicates transferrin as an important iron source in the host. However, we find that mutants ...
bronchiseptica must acquire iron (Fe) from the infected host. A vast amount of Fe within the host is sequestered within heme, a metalloporphyrin which is coordinately bound in hemoglobin and myoglobin. Utilization of hemoglobin and myoglobin as sources of nutrient Fe by B. bronchiseptica requires ...
Iron-deficient diet: There are two kinds of iron:heme(from animals) andnon-heme(from plants). Animal iron is much more bioavailable, so vegetarians/vegans need to prioritize iron in their diet. Dialysis: The kidneys makeerythropoietin, which stimulates RBC production; anemia is a frequent side...
By combining this approach with computational genome analysis, we identified hts (heme transport system), a gene cluster that promotes preferred heme iron import by S. aureus. Heme iron scavenging by means of hts is required for staphylococcal pathogenesis in animal hosts, indicating that heme iron...
