Expected Phenotypes Expected phenotypes refer to the expected results of susceptibility tests without testing. For a species to be included in the “expected resistant phenotype”, 90% or more should be considered resistant (e.g. Klebsiella pneumoniae vs. ampicillin). For a species to be included in…
Get to know moreImportant Additional Information Expected phenotypes, expert rules, and detection of resistance mechanisms are important complements to susceptibility testing and should be consulted before releasing results. Expected phenotypes help with validation of identification and susceptibility tests. Expert…
Get to know moreBacteria Most of EUCAST’s work is dedicated to defining breakpoints for bacteria that cause infections in humans. How to Use This Section: This page gives you access to information and services related to pathogenic bacteria. Important: All resources here are complementary. Please review them…
Get to know moreResistance Detection Successful treatment of infectious diseases relies on knowledge and understanding of when antimicrobial resistance is an expected phenotype of the organism, and when resistance to antimicrobial agents may develop. The following documents provide up-to-date advice on how to…

Get to know moreExpert Rules EUCAST expert rules (listed below) are a tabulated collection of expert knowledge on interpretive rules. These rules should be applied to antimicrobial susceptibility testing to rationalise testing, reduce errors, and make appropriate recommendations for reporting particular…
