Product Description
When it comes to detecting Listeria species in food, environmental, or clinical samples, the right medium makes all the difference. The Listeria Oxford Medium Base, Modified (M1781-500 gm) from Himedia is a specialized formulation designed to selectively isolate and identify Listeria monocytogenes and other Listeria species. This modified version enhances sensitivity and specificity, making it a trusted choice for microbiology labs, research institutions, and quality control facilities.
Listeria contamination is a serious concern in food safety, and accurate detection is critical. This medium contains selective agents like lithium chloride and antimicrobials that inhibit competing flora while promoting Listeria growth. The modified formula ensures better recovery rates, even from complex samples. Whether you’re a student learning microbiology techniques or a researcher conducting pathogen studies, this medium provides consistent and reliable results.
At eqipped, we understand the importance of precision in lab supplies. That’s why we offer this high-quality medium in a convenient 500 gm pack, ensuring you have enough for multiple experiments without compromising on performance. The powder form allows for easy preparation, and the microbiology-grade purity guarantees accurate outcomes every time.

Why This Medium Stands Out
Not all culture media are created equal. The Modified Listeria Oxford Medium Base is formulated with specific inhibitors and nutrients that target Listeria species while suppressing other bacteria. Here’s what sets it apart:
First, the inclusion of lithium chloride and antimicrobial agents like colistin and cefotetan helps inhibit gram-negative bacteria and other competitors, allowing Listeria colonies to thrive. The modified version also includes additional enhancements for improved selectivity, reducing false negatives in critical tests.
Second, the medium supports the growth of both healthy and stressed Listeria cells, which is essential for detecting low-level contamination in food or environmental samples. This makes it ideal for regulatory compliance testing, research, and educational purposes.
Finally, the powder form ensures a long shelf life and easy storage, while the 500 gm pack size is perfect for labs with moderate to high testing volumes. Whether you’re setting up a new lab or restocking supplies, this medium offers both convenience and reliability.
Applications in Research and Industry
This medium is widely used in various settings, including:
Food safety labs testing for Listeria contamination in dairy, meat, and processed foods.
Environmental monitoring programs checking surfaces and equipment for Listeria presence.
Clinical microbiology labs identifying Listeria in patient samples.
Educational institutions teaching students about selective media and pathogen detection.
For researchers working on Listeria pathogenesis or antibiotic resistance, this medium provides a consistent foundation for experiments. Its modified formula ensures that even subtle variations in Listeria strains are detectable, making it a valuable tool in both routine testing and advanced studies.
Preparation and Usage Tips
To achieve the best results, follow these guidelines when preparing the medium:
Dissolve 500 gm of the powder in 1 liter of distilled water, ensuring complete mixing.
Sterilize by autoclaving at 121°C for 15 minutes.
Cool to 45-50°C before adding any supplementary agents if required.
Pour into sterile Petri dishes and allow to solidify before use.
For optimal performance, store the prepared medium at 2-8°C and use within the recommended timeframe. Always follow standard microbiological practices to avoid contamination and ensure accurate results.
Safety and Handling
While this medium is designed for lab use, it’s important to handle it with care. The powder contains selective agents that may cause irritation, so wear appropriate personal protective equipment (PPE) like gloves and a lab coat during preparation. Work in a well-ventilated area or under a laminar flow hood to minimize exposure.
After use, dispose of the medium and any contaminated materials according to your lab’s biosafety protocols. This ensures both personal safety and environmental responsibility.
FAQs
What is Listeria Oxford Medium used for?
