Anaerobic Transport Media Inoculation Protocol
Obtain Specimen
For bowel:
-
Open 18-26 cm (8-12”) of bowel.
- Push aside bowel contents with gloved finger or tongue depressor.
-
Swab aggressively over the length of the open bowel, so that the swab presses deeply into mucosa and may even scrape off some mucosa.
- Be careful to hold swab shaft only at the end to prevent contamination
- For solid organs, follow protocol for aseptically collecting bacterial culture swabs from solid tissues
-
Check expiration date on transport media
- If blue/purple ring more than 3 mm thick at top of media do not use
-
Loosen screw cap
- Do not tip tube horizontally with cap open. There is an oxygen-excluding gas cap above the semisolid media
-
Insert swab into media once, to ~5mm from bottom
- Do not pull swab in and out
- Break or cut swab shaft evenly with lip of tube below the point of hand contact
-
Replace and tighten cap ASAP
- Do not over tighten
- Label tube with animal name/number, owner name, date, and site swabbed
-
Hold at room temperature (20-25ºC/68-77ºF) prior to shipping
- Do not refrigerate
-
Pack and deliver to lab within 72 hr of inoculation
- Do not chill
-
Protect from temperature extremes in transit
- Keep at 20-25ºC/68-77ºF)
Other Information
- Media has a color agent that changes to blue/purple when exposed to oxygen
- Some blue/purple change will occur after specimen is inserted in the media. This should convert back to normal color due to reducing agents in the media that remove oxygen
- Aerobic and fungal culture can also be performed from samples in this media
