Abstract
- In plasma clots the presence of ferritin-anti-ferritin complexes interferes with the bactericidal power of polymorphs against Klebsiella pneumoniae and Escherichia coli. Equivalent concentrations of apoferritin-antiferritin complexes, which lack Fe, do not have this effect and it is therefore suggested that the iron-binding capacity of lactoferrin in polymorphs plays an essential role in the bactericidal power of the cell. Similar results were obtained in vivo where ferritin- antiferritin complexes cause a high mortality in other- wise non-lethal infections. Evidence suggests that it is the iron in the ferritin which is responsible for the rapid intracellular bacterial growth and that lactoferrin normally plays an important protective role within the polymorphs.
