Hyaluronidase in Clinical Isolates of Propionibacterium acnes

Table 1

Study isolates.

Source of isolation, number of isolates	% of all cases	Number with clinically significant growth (%)
Total number, 197	100%	71 (36%)
Upper extremity, including hardware and native joints, 36	18%	24 (67%)
Lower extremity, 51	26%	7 (14%)
Spine/vertebral hardware, 45	23%	25 (49%)
Breast implant, 49	25%	9 (18%)
Penile implant, 7	4%	1 (14%)
Cardiac valve, 3	2%	2 (67%)
Blood, 1	1%	1 (100%)
Pacemaker, 5	3%	2 (40%)

The table shows the site of isolation of the study isolates and whether they were considered to represent clinically significant growth (i.e., not contaminants).
