抄録

Lactoferrin (LF), a member of the transferrin (TF) protein family, is an iron-binding protein that is known to interact with bacteria through a specific receptor. We examined the binding of bovine LF (bLF), bovine TF (bTF), and ovotransferrin (OTF) by Toxoplasma gondii using a fluorescence test and the streptavidin-biotin (SAB) method using biotin-streptavidin, and found that bLF, bTF, and OTF bound to the protein components of T. gondii. Furthermore, we confirmed that bLF, bTF, and OTF bound a 42 kDa soluble protein of T. gondii by far Western blot method. These results demonstrated that bLF binding proteins are present on T. gondii.<br>
