摘要
为进一步了解牙菌斑形成的机理，本实验比较了含Ⅰ、Ⅱ型菌毛的口腔粘性放线菌Ｔ＿（１４Ｖ）的３种突变株１４７（１￣－／２￣－）、５５１９（１￣＋／２￣－）和５９５１（１￣－／２￣＋），吸附于玻璃管壁的能力以及与变链菌Ｉｎ－ｇｂｒｉｔｔｅ、远缘链球菌６７１５、血链菌３４、血链菌ｂｌａｃｋｂｏｖａ发生共凝集反应的不同结果。并对３种突变株胞壁化学成分进行分析，显示细菌表面的特异性菌毛及疏水性大小对其吸附、凝集产生影响。
AbstractThree mutans of Actionmyces viscous T_(14v) lackingtypel (5951) , type 2 (5519) and both types of fimbriae( 147) were selected in this study. We compared the a-bility of their adsorption to the testtube wall, the resultof the cellular coaggregation between these mutantstrains and Streptococcus sanguis 34, Streptococcus sanguis black bova , Streptococcus mutans ingbritte, Streptococcus sobrinus 6715 and analysed the chemical char-acterization of cell walls of the three mutans. We foundthat the specific fimbriae and cell hydrophobicities hadgreat effect on the bacteria adsorption or coaggregation.
