Abstract: The 4.6 kb chloramphenicol resistance (Cm) plasmid, pSCS6, isolated from a naturally occurring Staphylococcus aureus biotype C encoded an inducible chloramphenicol acetyltransferase (CAT). The respective cat gene and its regulatory region were cloned. Sequence analyses revealed two open reading frames: one for a 9-amino acid leader peptide and the other for the 215-amino acid CAT monomer. Comparisons of the predicted CAT amino acid sequences revealed a high degree of similarity between CAT from pSCS6 and the CAT variants encoded by Cm plasmids of the pC221 family. These close structural relationships suggested an intraspecific exchange of Cm-determinants between Staph. aureus of human and bovine biotype. |
