What antibiotics are found in Thayer-Martin modified Thayer-Martin Martin Lewis?
Our Thayer-Martin supplement contains four antibiotics: vancomycin which inhibits gram-positive organisms, colistin which inhibits gram-negative bacteria, nystatin which inhibits yeasts and molds, and trimethoprim which is primarily added to inhibit swarming Proteus species.
What is the difference between Thayer-Martin and modified Thayer-Martin?
Thayer-Martin agar is a selective medium used for the isolation of gonococci (Neisseria gonorrheae) from specimens containing a mixed flora of bacteria and/or fungi e.g. urogenital specimen. Modified Thayer-Martin (MTM) agar is a GC agar base containing vancomycin, colistin, nystatin, and trimethoprim lactate (VCNT).
What antibiotics are in Martin Lewis agar?
The selective medium comprises the antimicrobial agents vancomycin, colistin, anisomycin (V-C-A Inhibitor) and trimethoprim, to suppress the normal flora. Vancomycin is active primarily against gram-positive bacteria. Colistin inhibits gram-negative bacteria, including Pseudomonas species.
What is Thayer-Martin agar used for?
Thayer-Martin Selective Agar is used for the isolation of pathogenic Neisseria from specimens containing mixed flora of bacteria and fungi. Carpenter and Morton described an improved medium for the isolation of the gonococcus in 24 h.
What can grow on Thayer Martin media?
Neisseria bacteria
It is used for culturing and primarily isolating pathogenic Neisseria bacteria, including Neisseria gonorrhoeae and Neisseria meningitidis, as the medium inhibits the growth of most other microorganisms.
Does Neisseria meningitidis grow on Thayer Martin Agar?
Remel Thayer Martin Agar (Modified) is a solid medium recommended for use in qualitative procedures for the isolation of Neisseria gonorrhoeae and Neisseria meningitidis.
Does Neisseria sicca grow on Thayer-Martin?
Unlike N. meningitidis and N. gonorrhoeae, the other Neisseria species (except N. lactamica) generally do not grow on selective media such as Thayer–Martin agar.
What is Jembec system?
The JEMBEC system is made up of a rectangular plastic tray which contains modified Thayer-Martin medium (1). The tray has a well into which a CO2-generating tablet is placed. The tray is placed inside a ziplock plastic bag (1).
What is the difference between chocolate agar and Thayer-Martin agar?
Chocolate Agar is a non-selective medium for the cultivation of fastidious bacteria, especially Neisseria and Haemophilus spp, from a variety of clinical specimens. Thayer Martin is used for the selective isolation of pathogenic Neisseria from specimens with mixed flora of bacteria and fungi.
