The pre-requisite of any transport medium is that it should be non-nutritive, semi-solid, and reductive and should be able to hamper self-destructive enzymatic reactions within the cells and in addition, must inhibit toxic oxidation reactions. Amies modified Stuart's Transport Medium by replacing glycerophosphate with an inorganic phosphate buffer and adding charcoal to the medium. This modified medium gave a higher percentage of positive results than the transport medium of Stuart. This medium contains sodium chloride (0.3% concentration) for the optimal preservation of Neisseria gonorrhoeae. Potassium, calcium and magnesium salts maintain osmotic equilibrium by controlling the permeability of bacterial cells. Phosphate buffer maintains pH of the medium. Sodium thioglycollate and agar aid in providing a reduced environment favourable for a wide range of bacteria. Charcoal neutralizes metabolic products toxic to gonococci. Amies Transport Medium provides a reduced environment due to the presence of sodium thioglycollate and small amount of agar. Calcium, magnesium, potassium and sodium salts help the survival of gonococcal cells and also control permeability of bacterial cells. Phosphates buffer the medium.
