A. CLSI has updated all the interpretive and QC charts for disk diffusion in the 2009 publication M2-A10 (and related publication M100-S19/M2 Supplemental Tables, 2009) Performance Standards for Antimicrobial Susceptibility Testing. Check to see if there is a more recent publication of this document at www.clsi.org/Source/Custom/Currentdocs.cfm?Section=Current_Versions_of_CLSI_Documents. The source for all CLSI publications is: Clinical and Laboratory Standards Institute (CLSI – formerly NCCLS) 940 West Valley Road, Suite 1400 Wayne, PA 19087-1898 (610) 688-0100 Website: www.clsi.
