The CLSI M45 document, titled "Guidance for Antimicrobial Susceptibility Testing of Infrequently Isolated or Fastidious Bacteria," is a specialized publication designed for clinical laboratory scientists, pathologists, and infectious disease specialists.

Unlike the comprehensive breakpoints in M100, M45 offers tailored recommendations for specific fastidious organisms that are not covered under general standards. Scope of the Guideline The M45 document covers:

The primary purpose of M45 is to standardize the pre-analytical, analytical, and post-analytical phases of blood culture testing. Variations in how blood cultures are handled can lead to false negatives (missing an infection) or false positives (contamination), both of which have severe consequences for patient care.

Without M45, labs would lack the standardized protocols needed to test pathogens like Aeromonas , Campylobacter , Neisseria meningitidis , or the slowly growing Mycobacterium species (non-tuberculosis). Variations in how blood cultures are handled can

While common pathogens like Staphylococcus aureus or Escherichia coli follow standard testing guidelines (such as CLSI M100), infrequent or fastidious organisms require specialized media, incubation conditions, and interpretive criteria. M45 provides these exact parameters to ensure accurate antimicrobial susceptibility testing (AST). Key Organisms Covered in M45

The CLSI M45 document is updated periodically to reflect emerging resistance data and newly approved antimicrobial agents. Authorized Acquisition
