Phage resistance is not correlated with the presence of matching CRISPR spacers in type II P. acnes strains. The pattern of resistance/susceptibility of the 9 type II P. acnes strains against 15 phages did not correlate with the presence/absence of matching CRISPR spacers, that is, the pink cells do not perfectly overlap with the cells containing red or orange pixels. P. acnes type II strains are shown in rows and the phages are shown in columns. Pink cells indicate that the bacterial strains are resistant to the corresponding phages. The colored pixels in each cell represent the CRISPR spacers encoded in each P. acnes strain. Each red pixel indicates that this spacer has an exact protospacer match in the corresponding phage. Each orange pixel indicates that this spacer has a partially matched protospacer (with one to two mismatches) in the corresponding phage. Gray pixels indicate no matched protospacers found in the corresponding phage.
