scope:

The data in the tables are valid only if the methodologies in CLSI document VET011 are followed. This standard contains information about disk and dilution susceptibility test procedures for aerobic and facultatively anaerobic bacteria. Clinicians need information from the microbiology laboratory for treating and/or confirming treatment decisions for their patients with bacterial infections and depend heavily on this information for treating their seriously ill patients. The clinical importance of antimicrobial susceptibility test results demands that these tests be performed under optimal conditions and that laboratories have the capability to interpret results based on the most current breakpoints and interpretive categories for antimicrobial agents used in veterinary medicine.

The tables presented in VET01S represent the most current information for drug selection, interpretation, and quality control using the procedures standardized in VET01.1 Users should replace previously published tables with these new tables. Changes in the tables since the previous edition appear in boldface type.
