Hyaluronidase in Clinical Isolates of Propionibacterium acnes

Figure 2

Kinetics of hyaluronidase production in Propionibacterium acnes. Three isolates were studied, including a hyaluronidase nonproducing (as determined by plate assay) isolate (P. acnes IDRL-7676) and two hyaluronidase-producing (as determined by plate assay) isolates (P. acnes IDRL-7751 and P. acnes IDRL-7844). Hyaluronidase production was measured by increased light transmission at OD₅₄₀. Sterile medium was used as a negative control.
