| Abstract: | 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. |
