Comparison of the prophage-like region in strains of P. acnes and P. avidum. A few type I-2 and a few type Ia strains like KPA171202 (KPA) and HL025PA1, respectively, possess a prophage-like region, while most type Ia (like strain 266) and type II and type III strains do not contain such a region. P. avidum strain ATCC25577 harbors a similar region, though the 3′-end differs in P. acnes. The comparison was done using the Artemis Comparison tool (ACT, Sanger Institute).
