Performance Standards for Antimicrobial Disk and Dilution Susceptibility Tests for Bacteria Isolated from Animals; Approved Standard\u2014Second Edition<\/p>\n","protected":false},"excerpt":{"rendered":"
If the susceptibility of a bacterial pathogen to antimicrobial agents cannot be predicted based on the identity of the organism alone, in vitro antimicrobial susceptibility testing of the organism isolated from the disease processes in animals is indicated. Susceptibility testing is particularly necessary in those situations where the etiologic agent belongs to a bacterial species for which resistance to commonly used antimicrobial agents has been documented, or could arise. A variety of laboratory techniques can be used to measure the in vitro susceptibility of bacteria to antimicrobial agents. This document describes the standard agar disk diffusion method, as well as standard broth dilution (macrodilution and microdilution) and agar dilution techniques. It also includes a series of procedures designed to standardize test performance. The performance, applications, and limitations of the current NCCLS-recommended methods are described. The tabular information in this document presents the most current information for drug selection, interpretation, and quality control. Only a few compounds have veterinary-specific interpretive criteria; so, human interpretive criteria are used for the majority of compounds. As more veterinary-specific information becomes available, these changes will be incorporated into future revisions of this document. NCCLS.
