Genotypic and Antimicrobial Characterisation of Propionibacterium acnes Isolates from Surgically Excised Lumbar Disc Herniations

Figure 2

Phylogroup distribution of P. acnes isolates recovered from excised disc tissue ( ). A total of one or more biopsy specimens recovered from 24/64 patients were positive for growth of P. acnes. Phylogroups were identified using a combination of recA and mAb typing. Five separate nucleus disc tissue samples were surgically removed from each patient as recommended by the IDSA [23]. P = patient number.
