Effect of Body Fluids and Macromolecular Substances on the Lysis of Group A Streptococci by Muramidases of Streptomyces albus.
The lysis of group A streptococci by muramidases of Streptomyces albus is strongly inhibited by human, rabbit, and calf serum as well as by human synovial fluids and pus. Rabbit antisera to heat-killed streptococci were no more inhibitory to the lysis of the streptococci by the lytic enzyme than normal rabbit serum. The results indicate that muramidases of S. albus will not be useful for the in vivo treatment of chronic granulomatous lesions which had been induced by insoluble cell wall components of streptococci.
