Six randomly selected strains of Staphylococcus aureus all exhibited the same gene order along the chromosome when mapped by the synchronous chromosomal replication procedure. Strains possessing multiple antibiotic resistance yielded a genomic map with all genes shifted toward significantly later replication times than in strains not bearing multiple antibiotic resistance. It appears that there is a unique site on the S. aureus chromosome for the initiation of replication.
