A Biological Safety Cabinet is recommended for specimen handling to minimize the risk of aerosolization of spores.

MIC results provided were determined by agar dilution.

MIC results for each antimicrobial agent for an isolate may commonly be ± 1 log2 (doubling dilution) different than what is posted on the FDA & CDC AR Bank website because this is the normal technical variability of antimicrobial susceptibility testing (see J. H. Jorgensen. 1993. J Clin Microbiol. Vol 31[11]: 2841-2844).

Propagation
MEDIUM
Medium: CDC Anaerobic Blood Agar (ANA BAP) or Brucella Blood Agar (BBA)

GROWTH CONDITIONS
Temperature: 37°C
Atmosphere: Anaerobic

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 ANA BAP or BBA
Use streak plate method to isolate single colonies
Incubate inverted plate at 35⁰C ± 2°C for 24hrs.
Storage Temperature & Biosafety
STORAGE TEMPERATURE: -70°C
