| Abstract: | The plasmids of a multiresistant "canine" Staphylococcus epidermidis-culture were investigated. Two small plasmids, the 4.55 kB chloramphenicol resistance (CmR-) plasmid pSC4 and the 4.45 kB tetracycline resistance (TetR-) plasmid pST 3 could be isolated. Detailed restriction maps of pSC 4 and pST 3 were constructed by double restriction endonuclease digests. The restriction maps revealed extensive structural homologies between pSC 4 from "canine" S. epidermidis and the CmR-plasmid pC 221 from "human" S. aureus as well as between pST 3 from "canine" S. epidermidis and the TetR-plasmid pT 181 from "human" S. aureus. These data suggested that an exchange of small plasmids between S. epidermidis and S. aureus might be possible. |
