The antistreptolysin activity of lysozyme

: The action of O-streptolysin on rabbit red corpuscles is inhibited by lysozyme, whereas the enzyme has no effect on termostable cytotoxic fraction of the toxin. Moreover little amounts of lysozyme canhance the anti-streptolysinic titers of human immune sera. These findings and the relationship between the biological activities of O-streptolysin are discussed.
