Buffered Listeria Enrichment Broth
Product Overview
Buffered Listeria Enrichment Broth is an essential medium designed for the selective enrichment and cultivation of Listeria spp. This broth is particularly crucial in public health and food safety laboratories, where the detection of pathogenic listeria is of paramount importance.
Intended Use
This specialized broth is used predominantly for the selective enrichment of Listeria monocytogenes and other Listeria species. It serves as a foundational culture for further identification and characterization of these microorganisms, vital for preventing foodborne illnesses.
Product Summary and Explanation
Originally described in 1926 by Murray, Webb, and Swann, Listeria monocytogenes represents a significant risk factor in the health sector, notably affecting vulnerable populations such as immunocompromised individuals and pregnant women. Transmission typically occurs through the consumption of contaminated foods, including turkey, frankfurters, coleslaw, pasteurized milk, and various cheeses.
Buffered Listeria Enrichment Broth features a modified formula in accordance with research by Lovett et al., emphasizing enhanced buffering capacity achieved through the incorporation of Disodium Phosphate. The pH range for optimal growth of Listeria spp. spans from 5.0 to 9.6, with the organisms displaying resilience even in food products outside these parameters. Listeria spp. are characterized as microaerophilic, Gram-positive, asporogenous, non-encapsulated, and motile short rods, with motility showing a pronounced presence at 20°C.
Key Features
- Enhanced buffering capacity to support microbial growth.
- Optimal growth conditions for Listeria spp. across a broad pH range.
- Supports effective isolation and identification through biochemical and serological methods.
- Essential for food safety testing and public health monitoring.
