Since the publication of this article, the authors have noticed errors in Figures 4a and 6, where one Propionibacterium acnes strain, HL103PA1, was mislabeled in Figure 4a, and the CRISPR spacers were shown incorrectly in Figure 6. The sentences concerning the errors in the article have been corrected accordingly.
The errors have now been rectified in the paper. The authors would like to apologize for any inconvenience this may have caused.
