Distribution of IS256 in different cocci. Sequence types (ST) of S. aureus are indicated by colors as follows: ST5, white; ST239, red; ST72, black; ST8, gray; and ST247, blue. Strains with fewer than three IS256 copies are not shown. Coagulase-negative staphylococci are green, and Enterococcus species are purple. IS256 was localized by NCBI BLAST and S. aureus MLST types were determined by MLST 1.8. S. aur., S. aureus; S. epi., Staphylococcus epidermidis.
