STUDIES OF PHAGOCYTOSIS OF GROUP A STREPTOCOCCI BY POLYMORPHONUCLEAR LEUCOCYTES IN VITRO

Abstract
Studies have been made on phagocytosis and killing of Group A streptococci during mixing with suspensions of leucocytes in vitro. Under appropriate test conditions an anti-phagocytic effect can be demonstrated for the streptococcal hyaluronic acid capsule as well as for its M protein.
