Abstract
Staphylococcus aureus chromosomal mutants which maintain pT181 and related plasmids at a much reduced copy number but which do not affect the replication of other plasmids have been isolated. The origin of replication and the initiator protein of the affected plasmids are the only elements required for the response to these mutations. The host mutations do not interfere with the pT181 replication control mechanism.
