Description
Stuart Transport Medium for Bacterial Specimen Preservation (5ml x 20 Tubes)
Stuart Transport Medium is an essential tool for the preservation and transport of bacterial specimens, ensuring their integrity for clinical microbiology and diagnostic laboratories. This transport medium is specifically designed to support the safe transport of pathogens such as Neisseria, Streptococcus pneumoniae, Salmonella, and other clinically significant bacteria. Its unique formulation creates an anaerobic environment that preserves the viability of the specimens while preventing contamination.
Key Features and Benefits:
- Anaerobic Conditions for Pathogen Preservation: The Stuart Transport Medium uses sodium thiosulfate and cysteine hydrochloride as redox agents. These substances absorb oxygen in the medium, creating a suitable anaerobic environment. This is crucial for transporting anaerobic bacteria and ensures optimal specimen survival.
- Stable pH and Preservation: The medium also contains glycerol phosphate buffer, which stabilizes the pH, preventing any potential pH-related degradation during transport. This ensures that bacterial cells remain viable throughout the transportation process.
- Hygienic and Leak-Proof Packaging: Each 5ml tube comes in a sealed, leak-proof plastic container, ensuring no contamination during handling. Each tube is individually packaged to prevent any cross-contamination, making it ideal for safely transporting a variety of clinical samples.
- Convenient for Clinical Diagnostics: This product is ideal for use in microbiology, especially for clinical diagnostics and the collection of specimen samples. Its applications extend across several types of bacteria, ensuring that healthcare professionals can effectively study pathogens such as Neisseria, Streptococcus pneumoniae, and Salmonella.
Composition of Stuart Transport Medium:
- Sodium glycerophosphate (10.0 g/L): Acts as a pH buffer to maintain stable conditions for bacterial growth.
- Cysteine hydrochloride (0.5 g/L): Functions as a reducing agent that facilitates anaerobic conditions, preserving anaerobic bacteria.
- Sodium thiosulfate (0.5 g/L): An additional reducing agent that absorbs oxygen to maintain an anaerobic atmosphere.
- Calcium chloride (0.1 g/L): Provides necessary calcium ions to maintain osmotic balance and cell integrity.
- Agar (5.0 g/L): Serves as the solidifying agent, allowing for easy handling of samples during transport.
- pH: 7.4 ± 0.2
How to Use:
- Preparation: Dissolve 16.1g of the medium in 1L of distilled water and distribute it into test tubes. Sterilize by autoclaving at 121°C for 15 minutes. Allow the medium to cool before use.
- Quality Control: Prepare control bacterial strains for validation and quality assurance purposes.
- Sampling: Swab the specimen with a sterile swab, transferring it into the transport medium. Ensure that the swab is fully immersed in the medium.
- Incubation and Culturing: After transportation, incubate the swab at room temperature for up to 48 hours, and then streak the specimen onto appropriate media (e.g., blood agar plates) for cultivation.
This transport medium is widely used by diagnostic laboratories for the safe transportation of clinical samples, ensuring that bacteria like Neisseria, Streptococcus pneumoniae, and Salmonella are transported without compromising their viability. The reliable formulation, which maintains anaerobic conditions, supports the successful isolation and identification of pathogens.
Applications:
- Bacterial Specimen Transport: Ideal for transporting anaerobic bacteria, including Neisseria gonorrhoeae, Streptococcus pneumoniae, and Salmonella spp.
- Microbiology: Essential for microbiological studies and diagnostic tests, providing a secure medium for specimen transfer.
- Clinical Diagnostic Laboratories: A must-have in clinical labs for the collection and safe transport of bacterial samples.
Why Choose Stuart Transport Medium:
- Proven efficacy in maintaining bacterial specimen viability.
- Leak-proof, easy-to-handle, and hygienic packaging.
- Suitable for a wide range of pathogenic bacteria, ensuring broad diagnostic applications.
