Description Back to Top
• Intended Use: GC Agar is used with hemoglobin and enrichment for the isolation and cultivation of Neisseria gonorrhoeae and other fastidious organisms.
• Product Summary and Explanation: GC Agar was introduced in 1947 with reduced agar content. While investigating the growth rate of gonococcus, a medium containing growth factors glutamine and cocarboxylase improved recovery. In 1964, Thayer and Martin formulated a medium incorporating the antibiotics Polymyxin B and Rostocetin, with added supplements, into GC Agar. Thayer and Martin improved their medium by replacing the antibiotics with a new solution of Colistin, Vancomycin, and Nystatin (CVN). In 1970, Martin and Lester improved the new Thayer-Martin Medium by increasing the agar and glucose, and adding Trimethoprim Lactate (T), calling it Modified Thayer-Martin (MTM) Medium. Martin and Lewis improved selectivity of MTM by increasing the concentration of Vancomycin and replacing Nystatin with Anisomycin for greater inhibition of yeasts, known as Martin Lewis (ML) Agar.6 Transgrow Medium is a transport medium incorporating either MTM or ML formulations.
