The effect of the presence of lipoteichoic acids (LTA) on a strain of Streptococcus equi was investigated. The LTA were extracted in a crude form from the S. equi strain and were found to sensitize sheep red blood cells so that they agglutinated with antibodies specific to purified LTA of group A streptococci. The crude LTA preparation was also able to inhibit the specific haemagglutination reaction involving group A streptococcal LTA and LTA antibodies. Neither the purified LTA from group A streptococci nor the anti-LTA serum interfered with the adherence of S. equi to equine epithelial cells.
研究了脂磷壁酸（LTA）的存在对马链球菌菌株的影响。从马链球菌菌株中以粗制形式提取LTA，发现其可使绵羊红细胞致敏，从而使其与A组链球菌纯化LTA的特异性抗体发生凝集。粗制LTA制剂还能够抑制涉及A组链球菌LTA和LTA抗体的特异性血凝反应。A组链球菌的纯化LTA和抗LTA血清均不干扰马链球菌对马上皮细胞的黏附。
