<i>Haemophilus somnus</i> Possesses Two Systems for Acquisition of Transferrin-Bound Iron

17 Jun 2004

Abstract excerpt

Haemophilus somnus strain 649 was found to acquire iron from ovine, bovine, and goat transferrins (Tfs). Expression of Tf receptors, as evaluated by solid-phase binding assays, required the organisms to be grown under iron-restricted conditions in the presence of Tf. Competition binding assays revealed the presence of two distinct Tf-binding receptor systems, one specific for bovine Tf and the other capable of...
