3 Based on FDA break points
4 Clinical and PK/PD data demonstrate colistin has limited clinical efficacy, even if an intermediate result is obtained. Alternative agents are strongly preferred. Colistin should be used in combination with one or more active antimicrobial agents. Consultation with an infectious disease specialist is recommended.
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
CategoryGene
 
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. For additional gene information please visit the Reference Gene Catalog - Pathogen Detection - NCBI (https://www.ncbi.nlm.nih.gov/pathogens/refgene), a non-redundant database of bacterial genes related to antimicrobial resistance, biocide and stress resistance, general efflux, virulence, or antigenicity.
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 20-24 hrs.
