Thermo Scientific™ Oxoid™ Listeria Selective Supplement

The Thermo Scientific™ Oxoid™ Listeria Selective Supplement (Oxford) (Freeze-dried) is a selective additive designed for the isolation and detection of Listeria monocytogenes. Used with the Listeria Selective Agar Base (CM0856B), this supplement enhances the medium’s selectivity, enabling reliable recovery of Listeria species from clinical, food, environmental, and veterinary samples.

Key Features

1. Selective for Listeria:
   • Optimized to support the growth of Listeria monocytogenes while suppressing non-target organisms.
2. Wide Application:
   • Effective for testing neonatal and vaginal samples, as well as food, environmental, and veterinary samples.
3. Freeze-Dried Format:
   • Convenient and long-lasting, ensuring ease of preparation and consistent performance.
4. High Yield Options:
   • Available in two formats:
     • SR0140B: Each vial for 2.5L medium
     • SR0140E: Each vial for 500mL medium
5. Reliable Detection:
   • Ensures accurate recovery and differentiation of Listeria spp., including Listeria monocytogenes, a major foodborne pathogen.

Applications

1. Clinical Microbiology

• Isolation of Listeria monocytogenes from neonatal and vaginal samples to aid in clinical diagnostics.

2. Food Microbiology

• Detection of Listeria spp. in raw and processed foods, including meat, dairy, and ready-to-eat products.

3. Environmental Monitoring

• Isolation of Listeria from environmental samples, including processing equipment and production facilities.

4. Veterinary Microbiology

• Testing animal-derived samples for the presence of Listeria monocytogenes to ensure animal and public health.
