Expression of Sme Efflux Pumps and Multilocus Sequence Typing in Clinical Isolates of Stenotrophomonas maltophilia

Abstract

The smeABC efflux pump was associated with multidrug resistance in clinical isolates of S. maltophilia. In particular, smeABC efflux pumps appear to perform an important role in ciprofloxacin resistance of S. maltophilia. The MLST scheme for S. maltophilia represents a discriminatory typing method with stable markers and is appropriate for studying population structures.
