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

Handling procedure
1. Put 6 to 8 ml of medium #1585 into a 13x100 mm screw cap test tube (small).  Add 3.0% cysteine (stock concentration, 2 ml/100 ml medium) and then fill the test tube to capacity with additional medium #1585.  Seal the test tube with a screw cap.

2. Let the tube sit at room temperature for 30 minutes before inoculating it with the rehydrated culture.

3. Aseptically take 0.5 ml of the pre-reduced medium and rehydrate the entire pellet.

4. Transfer the rehydrated pellet back into the screw cap test tube and close tightly.  (The test tube should be filled to capacity). 

5. Incubate the culture at 30oC under a tungsten lamp.

Handling notes
When incubated aerobically in the dark on #44 (Brain Heart Infusion) plates colonies are small, rounded, smooth, and entire with red pigmentation.

          When examined microscopically, the cells appear as spiral-shaped rods, in singles and pairs that are motile.

          After four to seven days, growth is evident by turbidity and a deep red pigmentation throughout the broth.  Once growth has been observed, the culture should be transferred to fresh broth.  Subsequent growth should be detected within 48 to 72 hours.
