Circular map of the L. monocytogenes strain RO15 chromosome with predicted prophage regions, CRISPR region and anti-CRISPR genes. Five prophage regions were predicted in the chromosome of L. monocytogenes strain RO15 using the PHASTER tool, as shown in figure with blue and green color. Two anti-CRISPR gene regions were annotated within the prophage region 4 and 5. The RliB-CRISPR/Cas system was located at the position 525–527 kbp, following CRISPR-I system located at the position 535–547 kbp with cas1–8 genes and a CRISPR array with 54 spacers
