| Popis | We have read with interest the paper by Fritzell et al. which suggests the association of bacteria, especially the anaerobic bacterium Cutibacterium acnes (previously Propionibacterium acnes), with pain-generating degenerated discs is likely to reflect contamination arising from the skin. We find this view surprising given that the recent studies of Capoor et al. [1] and Ohrt-Nissen et al. [2] directly visualized C. acnes as a biofilm within surgically removed intervertebral disc tissue. Such observations are practically impossible to explain by contamination as this would require the contaminant to form a biofilm deep within a retrieved nucleus tissue fragment during the brief time between removal and freezing. Against this background, we would like to highlight a series of potential methodological limitations within the Fritzell et al. study that could impact on their final results and conclusions regarding the association of C. acnes with degenerated discs. |
