SDD (Susceptible Dose Dependent)
S – I –R Interpretation (INT) derived from CLSI 2022 M100 S32
1 Reflects MIC of first component
2 SYN-R: is not synergistic with cell-wall active agent(e.g., ampicillin, penicillin and vancomycin)
3 SYN-S: is synergistic with cell-wall active agent (e.g., ampicillin, penicillin and vancomycin) if the cell-wall active agent is also susceptible
Device manufacturers and users of FDA cleared devices shall consult the FDA’s Antibacterial Susceptibility Test Interpretive Criteria       website for breakpoints recognized or recommended by FDA, and for information regarding FDA exceptions or additions to the applicable, recognized consensus standard.
Molecular Mechanisms of Resistance

Disclaimer:
The resistance mechanisms listed were identified by analysis of whole genome sequence using the ResFinder database (last updated June 2, 2016 and accessed on October 25, 2016). This analysis does not include mutations that may result in antibiotic resistance or resistance determinants added to newer versions of the ResFinder database or other antimicrobial resistance gene databases. Biosample accession numbers have been provided so that users can analyze the data on their own if so desired.
Propagation
MEDIUM
Medium: Trypticase Soy Agar with 5% Sheep Blood (BAP)

GROWTH CONDITIONS
Temperature: 35°C
Atmosphere: Aerobic

PROPAGATION PROCEDURE

Remove the sample vial to a container with dry ice or a freezer block. Keep vial on ice or block. (Do not let vial content thaw)

Open vial aseptically to avoid contamination

Using a sterile loop, remove a small amount of frozen isolate from the top of the vial

Aseptically transfer the loop to BAP

Use streak plate method to isolate single colonies

Incubate inverted plate at 35°C ± 2°C for 18-24 hrs.
