C. acnes phylotype I express significantly more roxP than other phylotypes, particularly during stationary phase growth. RNA was extracted from exponential and/or stationary phase C. acnes cultures, representative of type I (n = 6), type II (n = 5) and type III (n = 2) strains. qPCR quantifications of roxP mRNA were run in biological and technological duplicates, normalized against gapdh transcripts and evaluated using double delta Cq analysis. Grouped with their respective phylotypes, statistical significance was subsequently determined through a student’s t-test. ***p < 0.001, ****p < 0.0001.
