Panel:   Aspergillus fumigatus (ASP)
AR Bank # 0731 Aspergillus fumigatus
Study ID: ASP-01

Biosample Accession #: Biosample Accession data is not yet available.

   
Location: USA

MICs obtained by broth microdilution. Modal MIC is reported.

MIC results for each antifungal agent for an isolate may commonly be ± 2 log2 (doubling dilution) different than what is posted on the CDC & FDA AR Isolate Bank website because this is the normal technical variability of antifungal susceptibility testing.

Panel:  Aspergillus fumigatus (ASP)

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
Azoles L98H, TR34
 
Disclaimer:
The resistance mechanisms listed were identified by targeted gene sequencing. CYP51 sequence from Aspergillus fumigatus strain 237 (GenBank accession number AF338659) was used as the wild type reference.
Propagation
MEDIUM
Medium: Sabouraud Dextrose agar (SDA)

GROWTH CONDITIONS
Temperature: 30°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 SDA
Use streak plate method to isolate single colonies
Incubate inverted plate at 30⁰C for 48 hrs.
