Antibiograms

Antibiograms are important when designing antibiotic resistance studies to ensure the API targets the strains it’s supposed to target. Below are the antibiograms of several isolates for several species of bacteria in Emery Pharma’s inventory. We also have available a chart for strains of MRSA. A PDF version of these charts are available here.

Typical MIC values are given for each standard antibiotic and then the susceptibility is determined per CLSI guidelines:
R = Resistant, S = Susceptible, I = Intermediate

Tables of strains on this website are property of Emery Pharma and shall not be reproduced in any way.
