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.

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)

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 35⁰C ± 2°C for 20-24 hrs.
