BBL™ Thayer-Martin Selective Agar
Revision: 07     Revision Date: 09/01/2007    

Intended Use:

Thayer-Martin Selective Agar is used for the isolation of pathogenic Neisseria from specimens containing mixed flora of bacteria and fungi.



Product Summary:

Carpenter and Morton described an improved medium for the isolation of the gonococcus in 24 h.1 The efficiency of this medium, GC Agar supplemented with hemoglobin and yeast concentrate, was demonstrated in a study of twelve media then in use for the isolation of this organism.2 The medium was improved by replacing the yeast concentrate with BBL IsoVitaleX™ Enrichment, a chemically defined supplement developed specifically to aid the growth of gonococci, although it has broad application for other microorganisms, e.g., Haemophilus.3-5

Thayer-Martin Selective Agar was developed for the primary isolation of N. gonorrhoeae and N. meningitidis from specimens containing mixed flora taken from the throat, vagina, rectum, and urethra.4,6,7 Consisting of Chocolate II Agar with vancomycin, colistin and nystatin, it is formulated to minimize the overgrowth of gonococci and meningococci by contaminants, to suppress the growth of saprophytic Neisseria species and to enhance the growth of pathogenic Neisseria.

Warnings and Precautions:

For in vitro Diagnostic Use.

If excessive moisture is observed, invert the bottom over an off-set lid and allow to air dry in order to prevent formation of a seal between the top and bottom of the plate during incubation.

Pathogenic microorganisms, including hepatitis viruses and Human Immunodeficiency Virus, may be present in clinical specimens. "Standard Precautions"8-11 and institutional guidelines should be followed in handling all items contaminated with blood and other body fluids. After use, prepared plates, specimen containers and other contaminated materials must be sterilized by autoclaving before discarding.
