Clonal dissemination and mupA gene polymorphism of mupirocin-resistant Staphylococcus aureus isolates from long-term-care facilities in South Korea.

چکیده
We identified 25 high-level mupirocin-resistant (MuH) and 21 low-level mupirocin-resistant (MuL) Staphylococcus aureus isolates from eight long-term-care facilities (LTCFs). The pulsed-field gel electrophoresis patterns of 19 MuH and 19 MuL isolates from two facilities were identical for 18 and 15 isolates, respectively. The most predominant mupA restriction fragment length polymorphism type was found in 21 MuH isolates. We conclude that clonal transmission of MuH and MuL S. aureus strains occurred in these LTCFs. This is the first report of clonal transfer of mupirocin resistance in LTCFs.

BACKGROUND Mupirocin is a topical antimicrobial agent which is used for the treatment of skin and postoperative wound infections, and the prevention of nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA). However, the prevalence of mupirocin resistance in S. aureus, particularly in MRSA, has increased with the extensive and widespread use of this agent in hospital settings. Thi...
متن کاملAssociation of high-level mupirocin resistance and multidrug-resistant methicillin-resistant Staphylococcus aureus at an academic center in the midwestern United States.
Mupirocin is a topical antimicrobial used to eradicate methicillin-resistant Staphylococcus aureus (MRSA) colonization, usually in the absence of susceptibility testing. We hypothesized that high-level (HL) mupirocin resistance was associated with multidrug resistance (MDR). To this end, unique patient isolates identified at our institution during 2008 were stratified into those resistant to ≥ ...

Introduction: Mupirocin, an inhibitor of bacterial isoleucyl-tRNA synthetase, has used to treat staphylococcal skin infections as well as to eliminate nasal carriage of Staphylococcus aureus. Mupirocin resistant Staphylococcus aureus strains are seen worldwide but there is no report from Iran. In the present study, by using phenotyping methods (disk diffusion and E-test) in combination with P...

Background and purpose: Mupirocin is a topical antibiotic. This antibiotic can inhibit most of gram-positive cocci. Shortly after consuming the antibiotic mupirocin, resistance has emerged. The main purpose of this study was to determine mupirocin resistance in Staphylococcus strains isolated from nosocomial infections in the city of Arak. Material and Methods: A total of 150 Staphylococcus...
