CLSI to Publish 29th Edition of Annually Updated AST Supplement M100

12/13/2018

Wayne, Pennsylvania, USAThe Clinical and Laboratory Standards Institute announces the publication of its annually updated antimicrobial susceptibility testing (AST) supplement M100—Performance Standards for Antimicrobial Susceptibility Testing, 29th ed. M100 is available as part of a package with either M02—Performance Standards for Antimicrobial Disk Susceptibility, 13th edor M07—Methods for Dilution Antimicrobial Susceptibility Tests for Bacteria That Grow Aerobically, 11th ed, or all three documents together.  

Melvin P. Weinstein, MD, chairholder of M100 said, “M100 is a great resource for every microbiology laboratory that performs antimicrobial susceptibility testing.  Each year, M100 provides susceptibility breakpoints for recently introduced antibiotics and updated or revised breakpoints for older antibiotics based on the latest scientific information.  M100 also provides the latest information on methods for detecting newer resistance mechanisms.  Every microbiology lab should have the latest edition of M100.”

M02 covers the current recommended methods for disk susceptibility testing and criteria for quality control testing and includes the M02 Quick Guide. M07 covers reference methods for determining minimal inhibitory concentrations of aerobic bacteria by broth macrodilution, broth microdilution, and agar dilution. M100 includes annually updated tables for M02, M07, and M11.  

M02, 13th ed. Includes: 

  • Clarified definitions for breakpoint, interpretive category, and susceptible.
  • Reorganized and clarified information for staphylococci. 
  • Current recommended methods for disk susceptibility testing and criteria for quality control testing.
     

M07, 11th ed. Includes:  

  • Photographs of growth control examples and interpretation of skipped wells.
  • Reference methods for determining minimal inhibitory concentrations of aerobic bacteria. 

In addition to publishing these three documents, on Wednesday, February 20, 2019, 1:00–2:30 PM Eastern (US) Time and Thursday, February 21, 2019, 3:00–4:30 PM Eastern (US) Time CLSI will host the Annual AST Updates Webinar. This webinar will focus on changes and updates to M100 followed by a question and answer session.  For more information and to register, visit https://clsi.org/standards/products/microbiology/education/astupdate2019wr/.
