title: [The study of actinomyces viscosus adhere to teeth. IV. The study of salivary protein receptors of A. viscosus].
abstract: In order to determine the receptors of A. viscosus for adhesion, 7 kinds of main purified proteins from pellicle formed by whole saliva were tested. The result indicated that: 1. APRP, statherin, PRPG and SIgA were the receptors of standard and fresh isolated A. viscosus; 2. APRP and stather promoted the adherence of 5519 (1+2-) to HA, and SIgA promoted the adherence 5951 (1-2+) to HA; PRPG was the common receptor of the two fimbriae. It suggested that there were receptors not only type 1 fimbriae but also type 2 in pellicle. Two types of fimbriae were involved in the adherence of A. viscosus to pellicle. The difference existed in the receptor of adherence and the activity site of the same receptor.
