Product Description & Summary

TSA-NAM is an enriched medium for the isolation and cultivation of Tannerella forsythia. The nutritive base consists of casein and soy peptone. Hemin and vitamin K1 are added for the recovery of some fastidious anaerobes. This media is supplement with sheep blood and N-acetylmuramic acid, which are necessary growth factors for Tannerella forsythia. This media is prepared, dispensed, and packaged under oxygen-free conditions to prevent the formation of oxidized products prior to use.

Interpretation of Results & Limitations

If used properly, TSA-NAM will support good growth of Tannerella forsythia found in clinical specimens.

TSA-NAM will not provide complete information for identification of bacterial isolates. Additional test procedures and media are required for complete identification. It is recommended that a enriched media, such as Brucella Blood Agar (BRU, catalog #: AS-111) also be inoculated from the same clinical specimen to assure recovery of all species present. Consult reference materials for additional information.
