Biosafety Icon BSL 1

ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services. It is your responsibility to understand the hazards associated with the material per your organization’s policies and procedures as well as any other applicable regulations as enforced by your local or national agencies.

ATCC highly recommends that appropriate personal protective equipment is always used when handling vials. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. Upon thawing, the conversion of the liquid nitrogen back to its gas phase may result in the vial exploding or blowing off its cap with dangerous force creating flying debris. Unless necessary, ATCC recommends that these cultures be stored in the vapor phase of liquid nitrogen rather than submersed in liquid nitrogen.

Handling information

Medium
Temperature
37°C
Atmosphere
95% Air, 5% CO2
Handling procedure
  1. Open vial according to enclosed instructions.
  2. From a single tube of #416 broth (5 to 6 mL), withdraw approximately 0.5 to 1.0 mL with a Pasteur or 1.0 mL pipette and use to rehydrate the pellet.
  3. Aseptically transfer the rehydrated pellet back into the broth tube. Mix well.
  4. Use several drops of this suspension to inoculate a second tube of broth, a slant and/or a plate.
  5. Incubate tubes and plate at 37°C in an atmosphere of 5% CO2 for 24 to 48 hours. Loosen screw caps of all test tubes during the incubation period.
