BD 211763 - Difco Modified Oxford Medium ANMC SPL Selective Medium for Listeria Isolation
The BD 211763 Difco Modified Oxford Medium ANMC SPL is a specialized dehydrated microbiological medium formulated for the selective isolation and differentiation of Listeria species, particularly Listeria monocytogenes, from clinical, food, and environmental samples. This medium incorporates selective agents and esculin to support the growth of Listeria while inhibiting competing microorganisms.
Modified Oxford Medium provides a nutrient-rich base combined with antimicrobial supplements to suppress background flora. The hydrolysis of esculin by Listeria produces characteristic black colonies, enabling clear visual identification and differentiation during incubation. This makes it a critical medium for food safety testing, clinical diagnostics, and public health surveillance.
Key Benefits
Selective formulation enhances isolation of Listeria species by inhibiting competing organisms.
Esculin hydrolysis allows easy visual differentiation through characteristic colony coloration.
Supports reliable detection of Listeria monocytogenes in complex samples.
Dehydrated format ensures long shelf life, easy storage, and convenient preparation.
Compatibility and Applications
BD Difco Modified Oxford Medium is compatible with standard microbiology laboratory equipment, including Petri dishes, incubators, and enrichment systems. It integrates seamlessly into Listeria detection workflows.
Common applications include food safety testing, environmental monitoring, clinical diagnostics, and research involving Listeria species. It is widely used in food testing laboratories, public health institutions, hospitals, and research facilities.
Usage Guidelines
Reconstitute the dehydrated medium using distilled or deionized water according to manufacturer instructions. Sterilize and supplement with appropriate antimicrobial agents as required.
Pour into sterile Petri dishes and allow to solidify. Inoculate samples using aseptic techniques and incubate under recommended conditions.
