<I>Prevotella nigrescens</I> ATCC 25261 cells adhere well to protein-blocking hydroxyapatite (HA) which mimics a root surface in the periodontal pocket treated with proteases such as trypsin, proteinase K, chymotrypsin and papain. This study was done to clarify the inhibitory effect of α- and β- serum globulins on the adhesion of P. <I>nigrescens</I> ATCC 25261 cells to trypsin-treated HA. The inhibitory effect was found to be caused by the α1-antitrypsin (α1-AT) of α-globulin and the low-density lipoprotein (LDL) of P-globulin under experimental conditions. The most effective inhibition of al-AT on P <I>nigrescens</I> ATCC 25261 cell attachment to HA was achieved when α1-AT-treated trypsin was used. The most effective inhibition of LDL occurred when trypsin-treated HA was treated with LDL. Apo-transferrin (TF) and holo-TF, which are β-globulins, did not affect the attachment of P <I>nigrescens</I> ATCC 25261 cells to trypsin-treated HA. (J. Oral Sci. 45, 11-16, 2003)
