Abstract

Adsorption of all of eight strains of Streptococcus mutans to saliva-treated hydroxyapatite (S-HA) surfaces was inhibited by galactose and melibiose, but not by other neutral sugars tested. This observation supports the hypothesis that lectin-like components participate in the attachment of these streptococci to salivary glycoproteins on saliva-treated hydroxyapatite surfaces. Adsorption of all strains was also inhibited by iodoacetate and spermine; other amines tested reduced adsorption of some strains, but not others.

摘要

八株变形链球菌对经唾液处理的羟基磷灰石(S-HA)表面的吸附作用受到半乳糖和蜜二糖的抑制,但不受所测试的其他中性糖的抑制。这一观察结果支持了这样一种假说,即类凝集素成分参与了这些链球菌在经唾液处理的羟基磷灰石表面与唾液糖蛋白的附着过程。所有菌株的吸附作用也受到碘乙酸盐和精胺的抑制;所测试的其他胺类物质降低了部分菌株的吸附作用,但对其他菌株没有影响。
