Abstract
Summary: The chloramphenicol acetyltransferase gene (cat) of a 3·9 kb chloramphenicol resistance (CmR) plasmid from Staphylococcus intermedius, designated pSCS1, was cloned into an Escherichia coli plasmid vector. Sequence analysis revealed a high degree of base similarity with the cat gene of the S. aureus CmR plasmid pC221 but there were several differences in the regulatory region. A lesser degree of similarity was observed between the cat gene of the S. intermedius plasmid and the cat gene of the S. aureus plasmid pC194.
