  • a Data for isolates from 2001 to 2005 are from reference 20. A sequential sample of 60 nonduplicate isolates collected in 2007 and 2008 and a selected sample of isolates with an extended phenotype collected in 2007 and 2008 were examined for the presence of mPBP2GC. STs were determined by NG-MAST genotyping (10). All isolates listed in the table had the Pro[minus] (proline-requiring) auxotype. NA, not applicable.
