Specificities of Hyaluronidases Formed by Several Groups of Streptococci.

Hyaluronidases produced by strains of Groups A and B streptococci are serologically distinct. Hyaluronidases produced by strains of Groups C and G are serologically indistinct. Each of the latter is distinctly different from hyaluronidases formed by strains of streptococci, Groups A and B.
