Abstract Human leukocyte extracts, egg white lysozyme, cationic proteins, polymyxin, colimycin, and phenol are capable of releasing lipoteichoic acids (LTA) from group A streptococci andStrep, mutans. While the extraction of LTA by phenol is optimal at pH 4.7, the release of LTA from streptococci by the other agents is optimal at pH 7.4. LTA released by all agents was found to have the same sensitizing abilities, as determined by passive hemagglutination, and to have a similar chemical composition, as shown by thin-layer chromatography and radioactive scanning. The LTA-releasing capacity of all the agents is strongly inhibited by normal human serum. The possible role played by LTA released by leukocyte factors in the pathogenesis of tissue damage during bacterial infections is discussed.
