Abstract

The contribution of lipoteichoic acid (LTA) to the hydrophobic surface properties of group A streptococci was investigated in aqueous dextran-polyethylene glycol two-phase systems. Enzymatic digestions were performed to characterize the hydrophobic surface structure. The results obtained indicated that LTA is a major factor responsible for the hydrophobic character of the cell surface of group A streptococci. This was further supported by the similarity of partition in polymer two-phase systems between whole group A streptococci and tritiated LTA extracted from a group A streptococcal strain. Surface LTA was also determined on intact organisms by a new method measuring the adsorption of antibodies to LTA to the bacterial surface. A correlation was found between the content of surface LTA and the hydrophobicity of the group A streptococci. We conclude that surface-associated LTA is the major factor determining surface hydrophobicity of group A streptococci.

摘要

在葡聚糖 - 聚乙二醇双水相体系中,研究了脂磷壁酸(LTA)对A群链球菌疏水表面特性的贡献。进行酶消化以表征疏水表面结构。所得结果表明,LTA是导致A群链球菌细胞表面具有疏水性的主要因素。从A群链球菌菌株中提取的全A群链球菌与氚标记的LTA在聚合物双相体系中的分配相似性进一步支持了这一点。还通过一种测量LTA抗体吸附到细菌表面的新方法,在完整生物体上测定了表面LTA。发现表面LTA的含量与A群链球菌的疏水性之间存在相关性。我们得出结论,表面相关的LTA是决定A群链球菌表面疏水性的主要因素。
