TRANSPORT SWABS W/ AMINES MEDIUM (D)

Description

Transport Medium is generally a non-nutrient, reductive medium which hampers the self-destructive enzymatic reactions within the cells and also inhibits toxic oxidation effects. Transport Medium was primarily developed in a semisolid form by Moffett et al and Stuart et al for carrying gonococcal specimens. However Cary and Blair observed the problem of overgrowth of contaminating organisms while carrying faecal specimens containing Shigellae. It was seen that the contaminants derive their energy from the glycerophosphate and therefore a buffer having inorganic salts was a better replacement for glycerophosphate. Amies modified Stuart’s Transport Medium by replacing glycerophosphate with an inorganic phosphate buffer, provides a reduced environment due to the presence of sodium thioglycollate and small amount of agar. Amies Medium is devoid of methylene blue.
