NorA is a Staphylococcus aureus multidrug transporter that exports structurally distinct compounds including fluoroquinolones. In this study norA- like genes of Staphylococcus epidermidis ( norA SEP ) and Staphylococcus haemolyticus ( norA SHAE ) were identified and sequenced. The nucleotide identity of norA SEP and norA SHAE with norA was 75.3 and 74.1%, respectively, and the amino acid identity 87.7 and 86%, respectively. Inactivation of norA SEP increased the ciprofloxacin susceptibility of E. coli DH5α carrying the pB SK 198 norA SEP EZ cat norA SEP plasmid., Competing Interests: Conflict of Interest: All authors declare no conflicts of interest in this paper.
