title: Hyaluronidase activity of group B streptococci.
abstract: Extracellular hyaluronidase produced by the clinical isolates of various serotypes of group B streptococci was studied using a sensitive spectrophotometric micromethod. Enzyme activity, up to 4.6 units per optical (Klett) density unit of the bacterial suspension was present in the culture supernatants of 38 of the 39 strains tested. There was no association between high levels of hyaluronidase activity and specific serotypes or clinical sources of strains.
