BD 220909 - Lowenstein-Jensen Medium Egg-Based Selective Culture Medium for Mycobacteria

BD 220909 - Lowenstein-Jensen Medium Egg-Based Selective Culture Medium for Mycobacteria

The BD 220909 Lowenstein-Jensen Medium is a specialized egg-based culture medium designed for the isolation and cultivation of mycobacteria, including Mycobacterium tuberculosis. This medium provides a nutrient-rich environment that supports the slow growth characteristics of mycobacterial species while incorporating selective agents to inhibit contaminating organisms.

Formulated with coagulated eggs, glycerol, and malachite green, Lowenstein-Jensen Medium ensures optimal growth conditions while suppressing unwanted microbial flora. It is widely used in clinical microbiology laboratories for the diagnosis of tuberculosis and other mycobacterial infections, as well as in research and public health settings.

Key Benefits

The egg-based formulation provides essential nutrients and proteins required for the growth of fastidious mycobacteria.

Malachite green acts as a selective agent, reducing contamination and improving the isolation of target organisms.

Supports reliable and reproducible growth of Mycobacterium species, aiding in accurate diagnosis and research outcomes.

Widely recognized and standardized medium, ensuring compatibility with established laboratory protocols.

Compatibility and Applications

BD Lowenstein-Jensen Medium is compatible with standard laboratory incubation systems and microbiological workflows. It is typically used in conjunction with specimen processing and decontamination procedures for mycobacterial culture.

Applications include clinical diagnosis of tuberculosis, identification of non-tuberculous mycobacteria, and research studies focused on mycobacterial growth and drug susceptibility.

This medium is commonly used in hospitals, diagnostic laboratories, public health institutions, and research facilities.

Usage Guidelines

Prepare or use the medium according to manufacturer instructions. Inoculate the medium with processed clinical specimens or laboratory cultures using sterile techniques.

Incubate under recommended conditions, typically at controlled temperatures for extended periods due to the slow growth rate of mycobacteria.

Monitor regularly for colony development and record observations according to laboratory protocols.

Certifications and Safety Standards

The BD 220909 Lowenstein-Jensen Medium is manufactured under ISO-certified quality systems to ensure consistent performance and reliability.

Each batch undergoes rigorous quality control testing to meet microbiological standards, supporting its use in clinical diagnostics and research applications.

Comparison with Competitors

Compared to non-standardized media, BD Lowenstein-Jensen Medium offers consistent formulation and reliable selective properties, ensuring dependable results in mycobacterial culture.

BDs stringent quality control processes reduce variability between batches, whereas lower-quality alternatives may compromise growth performance and contamination control.

The established reputation of BD in microbiology diagnostics makes this medium a preferred choice for laboratories requiring accurate and reliable culture results.

Typical User Profile and Application Scenarios

This product is intended for microbiologists, clinical laboratory technicians, and infectious disease specialists involved in mycobacterial diagnostics and research.

It is commonly used in tuberculosis testing laboratories, hospital microbiology departments, public health institutions, and academic research facilities.

Best Practices for Use and Maintenance

Store the medium under recommended conditions to preserve its integrity and performance. Avoid exposure to contamination during handling and inoculation.

Use sterile techniques throughout preparation and inoculation processes to maintain culture purity.

Monitor incubation conditions carefully, as mycobacteria require extended incubation periods for visible growth.

Regulatory and Safety Information

The BD Lowenstein-Jensen Medium is intended for laboratory use and complies with applicable standards for microbiological culture media. It supports adherence to institutional and regulatory guidelines for diagnostic testing.

Users must follow biosafety protocols when handling potentially infectious specimens and dispose of used media according to local regulations.
