Cary–Blair Transport Medium is a microbiological transport medium widely used to preserve and transport stool and rectal swab specimens containing suspected enteric pathogens. It helps maintain the viability of microorganisms during the time between specimen collection and laboratory testing.
The Cary–Blair formulation is recognized as a suitable transport medium for enteric bacteria and has a long history of use in clinical microbiology. The FDA’s Bacteriological Analytical Manual identifies Cary–Blair as medium M31 and describes its formulation as a semisolid medium with an alkaline pH.
What Is Cary–Blair Transport Medium?
Cary–Blair transport medium is designed primarily for specimen preservation and transportation, rather than promoting extensive bacterial growth.
Its semisolid formulation helps maintain the collected specimen during transportation while limiting changes that could affect subsequent microbiological examination.
Cary–Blair is commonly associated with enteric pathogens such as:
- Сальмонелла
- Шигелла
- Vibrio
- Pathogenic Escherichia coli
The exact suitability depends on the target organism and laboratory testing method.
What Is Cary–Blair Transport Medium Used For?
Cary–Blair transport medium is primarily used for the preservation and transportation of specimens intended for bacteriological examination, especially specimens associated with gastrointestinal infections.
Common applications include:
- Stool specimen transportation
- Rectal swab specimen transportation
- Enteric bacterial pathogen testing
- Clinical microbiology
- Foodborne disease investigations
- Public-health microbiology
- Laboratory culture and identification workflows
Why Choose Cary–Blair Transport Medium?
Several characteristics make Cary–Blair useful for enteric specimen transportation:
- Specimen preservation: Helps maintain viable microorganisms during transportation.
- Semisolid formulation: Helps keep the inoculated swab in contact with the medium.
- Enteric pathogen application: Suitable for workflows involving a range of bacterial gastrointestinal pathogens.
- Convenient handling: Transport tubes with integrated swabs simplify specimen collection and transportation.
- Flexible application: Can be incorporated into clinical and microbiological specimen workflows.
Cary–Blair Transport Medium with Swab
А Cary–Blair transport medium with swab combines specimen collection and transportation in one convenient system.
A typical workflow is:
- Collect the stool or rectal specimen using the sterile swab.
- Insert the swab into the Cary–Blair transport tube.
- Securely close the tube.
- Label the specimen according to laboratory requirements.
- Transport the specimen under the specified conditions.
This integrated design can help simplify specimen management and reduce the number of separate components required during collection.
How to Choose a Cary–Blair Transport Medium Supplier
When sourcing Cary–Blair transport medium for clinical or microbiological applications, buyers should evaluate more than the medium formulation alone.
Consider the following factors:
Product Quality
Check the materials, medium formulation, бесплодия, packaging integrity, срок годности, and quality-control procedures.
Swab Compatibility
The swab should be appropriate for the intended specimen and downstream testing procedure. Different swab materials may have different characteristics, so the appropriate option should be selected according to the intended application.
Certifications and Quality Management
For medical and diagnostic applications, buyers should review the supplier’s applicable certifications and quality-management systems.
Packaging and Shelf Life
Individually packaged collection systems can simplify distribution and help maintain product integrity before use. MEIDIKE GENE lists a 12-month shelf life for its Cary–Blair transport medium product.
OEM/ODM Capability
For distributors, диагностические бренды, и медицинские компании, OEM/ODM capability can be valuable when customized packaging, маркировка, Характеристики, or procurement requirements are needed.
