Molecular characterization of resistance to mupirocin in methicillin-susceptible and -resistant isolates of Staphylococcus aureus from nasal samples

Abstract

A total of 15 of 101 (14.8%) nasal methicillin-resistant Staphylococcus aureus (MRSA) isolates exhibited mupirocin resistance (Mup(r)) compared with 1 of 154 (0.6%) methicillin-susceptible Staphylococcus aureus isolates. A total of 14 (93%) isolates exhibiting high-level Mup(r) belonged to a single clone. Horizontal plasmid transfer and transmission of Mup(r) strains contribute to a high incidence of Mup(r) MRSA at our institution.

PFGE DNA patterns of Mupr S. aureus isolates from nasal samples. Lanes 1 to 7 represent genotypes A1 (isolate 1), A2 (isolate 3), A3 (isolate 4), A4 (isolate 2), A5 (isolate 6), B (isolate 7), and C (isolate 13), respectively. Lanes 8 to 11 represent the banding patterns of paired Mups and subsequently recovered Mupr S. aureus isolates (isolates 5, 12, 14, and 15) from nasal samples of four patients.
