Transport Medium Stuart is recommended for the preservation and transportation of Neisseria species and other fastidious organisms from the clinic to laboratory. Stuart Transport medium was originally designed by Stuart while studying Gonococci. Later the Stuart Medium was modified for the transportation of gonococcal specimens for culturing. Ringertz included thioglycollate in the Stuart Medium and omitted charcoal. This medium may be used for the transportation of many fastidious organisms including anaerobes by maintaining the organism's viability without significant multiplication . Crooks and Stuart suggested the addition of Polymyxin B sulphate which facilitates the recovery of Neisseria gonorrhoeae. This medium is a chemically defined, semisolid, non-nutrient medium which prevent microbial proliferation. Because of this composition the medium ensures that microorganisms present are able to survive for a sufficiently long period of time. The medium provides an adequate degree off anaerobiosis which can be monitored by means off the redox indicator methylene blue. Calcium chloride along with sodium glycerophosphate act as good buffering agent and also maintains osmotic equilibrium in the medium.
