The nucleotide sequence of Xbal-Mbol fragment of pKH7, a chloramphenicol-resistant($Cm^{r}$) plasmid isolated from multidrug-resistant S. aureus SA2, has been determined. Xbal-Mbol fragment of pKH7 was found to contain two ORFs. One ORF encoded Rap and the other encoded CAT protein. The deduced amino acid sequences of Rep and CAT of pKH7 were compared to those of pUB112 and pC221. Comparisons revealed that there was one amino acid difference in CAT between pKH7 and pUB112. CAT of pKH7 exhibited 98.6% amino acid identity to that of pC221. In case of Rep proteins, a slightly lower homology of 96.4% and 86.7% in amino acid sequences was observed between pKH7 and pUB112 and between pKH7 and pC221, respectively.
