[Method of quantitative determination of staphylococcal hyaluronidase activity].

The proposed method for measuring hyaluronidase activity of microorganism is based on prevention of hyaluronic acid clot formation with rivanol under the effect of hyaluronidase. This made possible the quantitative and qualitative detection of hyaluronidase activities of different staphylococcus species and strains. The maximum level of the enzyme and highest rate of its detection were typical of St. aureus. Its strains producing hyaluronidase in quantities of at least 0.5 IU are significantly (p < 0.01) more often isolated from medical staff.
