BD 211742 - Difco Fraser Broth SPL, Dehydrated Culture Medium for Listeria Enrichment
The BD 211742 Difco Fraser Broth SPL is a dehydrated culture medium formulated for the selective enrichment of Listeria species from clinical and environmental samples. This specialized medium is designed to support the growth of Listeria monocytogenes and other Listeria species, aiding in the detection of Listeria in food and environmental microbiology testing.
Manufactured by BD, Fraser Broth SPL provides an optimized environment for the selective growth of Listeria, ensuring accurate and reliable results in food safety, clinical, and research applications.
Key Benefits
Supports the selective enrichment of Listeria species, especially Listeria monocytogenes, in complex environmental and food samples. Dehydrated format allows for flexible preparation based on laboratory needs. Reliable nutrient composition ensures consistent results and reproducibility. Manufactured under strict quality control standards for dependable microbiological performance.
Compatibility and Applications
The BD 211742 Difco Fraser Broth SPL is compatible with standard microbiological laboratory equipment, including autoclaves, incubators, and sterile culture tubes. It integrates easily into established Listeria enrichment protocols commonly used in food microbiology, clinical diagnostics, and public health laboratories.
Typical applications include the detection and isolation of Listeria monocytogenes and other Listeria species from food, clinical specimens, environmental samples, and manufacturing environments. It is particularly useful in regulatory testing and pathogen surveillance programs.
Usage Guidelines
Prepare the medium by dissolving the appropriate amount of dehydrated powder in purified water according to the manufacturers instructions. Sterilize the prepared broth using autoclave conditions. Dispense into sterile culture tubes or flasks, and allow to cool. Inoculate the sample under aseptic conditions and incubate according to established laboratory protocols for Listeria enrichment. After incubation, subculture onto selective agar plates for further analysis.
Certifications, Safety Standards, and Regulatory Approvals
BD culture media are produced under regulated quality management systems designed to ensure performance reliability and consistency. Quality control testing confirms that Difco Fraser Broth SPL supports expected growth and selective enrichment, making it compliant with microbiological standards used in food safety and clinical diagnostics.
Comparison with Competitor Products
Compared with other Listeria enrichment broths, BD Difco Fraser Broth SPL provides a specifically formulated environment optimized for Listeria species growth, reducing the need for further selective steps. BD microbiology products are widely recognized for their consistent, high-quality formulations and performance in complex sample types.
Typical User Profile and Application Scenarios
This product is used by microbiologists, clinical laboratory technologists, food safety experts, and public health professionals responsible for the detection of Listeria species. It is especially valuable in laboratories involved in food safety testing, clinical diagnostic microbiology, and environmental pathogen monitoring.
Best Practices for Use and Maintenance
Store the dehydrated medium in a cool, dry environment, protected from moisture. Ensure containers are tightly sealed after each use. Prepare the medium according to the manufacturer's instructions using calibrated equipment. Perform routine quality control testing with known Listeria strains to ensure medium performance.
Regulatory and Safety Information
Although microbiological culture media are laboratory-use products rather than direct patient-use medical devices, they are manufactured under strict quality control systems to ensure accurate pathogen detection and support regulatory compliance. Proper biosafety procedures should be followed when handling enriched culture media and suspected pathogen samples.
