Compairison of the SaPI. Nucleotide matches of SaPIbov, SaPI-S0385 and SaPI5 of S. aureus ET3, S0385 and USA300 FPR3757, respectivly dislayed using ACT. ORFs are represented by coloured boxes. The red bars indicate BLASTN matches between the elements, which mainly concern regions encoding genes that are essential for SAPI replication. The unique region in SaPI-S0385 contains the scn and vwb genes.
