CARRY-BLAIR MEDIUM BASE (TRANSPORT MEDIUM W/O CHARCOAL)

Description

Transport Medium is a non-nutritive, chemically defined, semisolid, buffered medium. The sole purpose of this medium is to maintain the viability of organisms during the time from collection to examination of the specimen. Transport Medium should be essentially non-nutritive so that the test organisms do not increase in numbers during transport. Transport media were originally formulated by Stuart et al for carrying gonococcal specimens to the laboratory. Cary and Blair devised a new medium containing fewer nutrients, low oxidation-reduction potential and a high pH. Cary-Blair Medium w/o Charcoal is used for collection and transport of clinical specimens. It is also recommended by APHA and various authors for transport of specimens. Since this transport media has a high pH, viability of Vibrio cultures can be maintained for a longer duration. This medium also facilitates the recovery of Salmonella and Shigella species.
