Thermo Scientific™ Oxoid™ Cary-Blair Transport Medium (Dehydrated)

The Thermo Scientific™ Oxoid™ Cary-Blair Transport Medium (Dehydrated) is a reliable solution for the collection, transport, and maintenance of clinical specimens suspected to contain enteric pathogens. Based on the formulation developed by Cary and Blair, this medium is designed to prevent bacterial overgrowth while ensuring the survival of target pathogens. Its low nutrient content and buffering system make it ideal for transporting specimens under field and laboratory conditions.

Key Features

1. Prevents Bacterial Overgrowth:
   • Inhibits growth of non-target bacteria such as Escherichia coli, Citrobacter freundii, and Klebsiella aerogenes.
2. Ensures Pathogen Survival:
   • Maintains low oxidation-reduction potential, allowing survival of anaerobic and fastidious bacteria.
3. Versatile Use:
   • Suitable for field surveys and laboratory workflows. Particularly effective for the transport of Vibrio parahaemolyticus and other enteric pathogens.
4. Supports Anaerobic Bacteria:
   • Can be prepared as a pre-reduced anaerobic sterilized medium (PRAS) for transporting anaerobic organisms.
5. High Yield:
   • One 500g package prepares 37.6L of medium, ensuring cost-effective testing for high-volume laboratories.

Applications

1. Clinical Microbiology

• Transport of clinical specimens, including rectal swabs, suspected of containing enteric pathogens such as:
  • Vibrio spp.
  • Salmonella spp.
  • Shigella spp.

2. Field Surveys

• Ideal for remote sample collection and transport during field investigations.

3. Laboratory Workflows

• Transport of fastidious anaerobic bacteria to central diagnostic laboratories.
