Genotypic and phenotypic characteristics of methicillin-resistant Staphylococcus aureus isolates at UCMC from 2004-5 and 2008.

aMLST clonal complex designations vary with time. The clonal cluster designations indicated here were accurate at the conclusion of 2008.bslv, single locus variant with no assigned multilocus sequence type (MLST).c1-31-1-1-12-1-40 denote the allotypes of 7 genes (arcC, aroE, glpF, gmk, pta, tpi, and yqiL) that determine this undefined MLST type.d7 MRSA isolates from 2004-5 had multiple or no ccr genes and were thus considered nontypable.eIncludes intermediate susceptibility results as resistant. In some cases, isolates were not tested for clindamycin, ciprofloxacin, erythromycin susceptibility, and the number tested are indicated in the table as the denominator for each relevant category.
