CRISPR profiles in nine Moritella viscosa strains indicating matches between spacers or other genomic elements in M. viscosa. Each spacer inn all M. viscosa strains are presented in numerical order (latest acquired is first) in the first row. Spacer ID’s in Additional file 3: Data S1 are named by its bacterial affiliation and numbered progressively where the highest number designates the last obtained spacer. Percentage and the number of identical spacers shared between M. viscosa strains are shown in detail in Table 1. Green spacers indicate identical spacers found in two or more M. viscosa strains. Light green indicate spacers with one mismatch to spacers in other M. viscosa strains. Black spacers indicate spacers found in specific M. viscosa spacer-arrays that are identical to prophage genes identified in other M. viscosa strains. Red spacers indicate spacers found in specific M. viscosa spacer-arrays that are identical to plasmid genes identified in other M. viscosa strains
