Polysaccharidases of Group A Streptococci [PDF]

Journal of General Microbiology, 1951
SUMMARY: Proteinase produced by Group A streptococci was associated with a decrease in hyaluronidase production which was not related to any other known environmental condition. The concentration of proteinase which was correlated with decreased hyaluronidase production was constant for a given strain.
