Figure 3: Genomic inversion in HL096PA1. (a) Genomic inversions observed in P. acnes strains HL096PA1 and ATCC11828 compared to P. acnes strain KPA171202. (b) Primer sets I–V designed to verify the genomic inversion in HL096PA1. (c) PCR amplified DNA fragments of the inverted regions shown on an agarose gel. Primers, target genomes, and the predicted sizes of the amplicons are shown in the table. HL, strain HL096PA1; KPA, strain KPA171202.
