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.

No disclaimer.
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.
Storage Temperature & Biosafety
STORAGE TEMPERATURE: -70°C

BIOSAFETY LEVEL: 2

Appropriate safety procedures should always be used with this material. Laboratory safety is discussed in the current publication of 'BioSafety in Microbiological and Biomedical Laboratories' from the U.S. Department of Health and Human Services, Centers for Disease Control and Prevention, and National Institutes of Health.
