| 摘要 |
A selective culture medium for detecting MRSA and selective drug or multidrug resistant microorganisms where the expression of said (multi)drug resistance is by virtue of the production by said microorganisms of 13- lactamase enzymes. The medium comprises a broad spectrum antibiotic capable of selectively inhibiting growth/replication of (a) organisms that do not produce b -lactamase enzymes, (b) organisms that while producing b -lactamase do not exhibit an ESBL or AmpC phenotype and (c) methicillin-susceptible S. aureus, and a compound capable of inducing production of b -lactamases in an organism, and which compound is included at a concentration that is subinhibitory for growth of said microorganism. Also provided are a method and kit for selectively isolating any MRSA and/or ESBL or AmpC b -lactamase producing microorganisms present in a sample using the selective culture medium. |
