 | Amies with Charcoal
3/404
Amies introduced his modification of Stuarts Transport Medium to overcome a number of problems. Stuarts Transport Medium suffered from overgrowth by coliforms that were capable of utilising sodium glycerophosphate. Amies replaced the problem component with an inorganic phosphate buffer system. Calcium and magnesium salts are added to control the permeability of the bacterial cell wall and thus prolong their survival. The addition of charcoal to the medium extended the survival time of Neisseria gonorrhoeae from 24 to 72 hours.
