BD 211407 - Mannitol Salt Agar Selective and Differential Medium for Staphylococcus Isolation, 500G
The BD 211407 Mannitol Salt Agar (MSA) is a high-quality selective and differential culture medium formulated to isolate and identify Staphylococcus species, particularly Staphylococcus aureus. Its high salt concentration (7.5% NaCl) effectively inhibits most non-staphylococcal bacteria, while mannitol and phenol red serve as differential indicators, allowing rapid visual differentiation of mannitol-fermenting strains. Manufactured with BDs rigorous quality controls, this medium ensures consistent colony morphology, clear color reactions, and reliable performance across clinical, industrial, and research microbiology laboratories.

Key Benefits
BD Mannitol Salt Agar offers excellent selectivity for Staphylococcus species, reducing interference from competing organisms. The medium supports easy identification of S. aureus by producing bright yellow zones from mannitol fermentation, while non-fermenters maintain a red or pink background. High clarity, optimized pH, and nutrient balance allow fast, accurate differentiation. BDs stable formulation provides consistent results, essential for diagnostic reliability and quality-control workflows.
Compatibility and Applications
BD 211407 MSA is widely used for:
- Isolation and differentiation of S. aureus from mixed cultures
- Screening carriers in hospital and community settings
- Food and beverage industry hygiene monitoring
- Environmental sampling in pharmaceutical and cleanroom environments
- General microbiology teaching and research applications
It supports growth of:
- Staphylococcus aureus (mannitol fermenting)
- Staphylococcus epidermidis (non-fermenting)
- Other salt-tolerant Gram-positive cocci
Usage Guidelines
Using aseptic technique, streak the specimen onto the surface of the Mannitol Salt Agar plate. Incubate at 3537C for 2448 hours. Mannitol-positive colonies will appear yellow with surrounding yellow zones, while non-fermenters remain pink/red. Confirm identification using additional biochemical or molecular tests when required. Store plates under refrigeration and avoid exposure to excessive heat or dehydration.
Certifications, Safety Standards, and Regulatory Approvals
BD 211407 MSA is manufactured in ISO 9001 and ISO 13485 certified facilities. It meets FDA and CE requirements for in vitro diagnostic (IVD) microbiological media. Each batch undergoes rigorous QC testing for sterility, selectivity, differential reactions, and growth support using validated S. aureus and S. epidermidis control strains.
Comparison with Competitor Products
Compared with other MSA brands, BD Mannitol Salt Agar provides sharper differential reactions, superior salt stability, and more consistent colony morphology. Competitor media may show inconsistent color change, weaker selectivity, or variable plate hydration. BDs consistent formulation ensures predictable, high-clarity results essential in diagnostic and industrial microbiology.
Typical User Profile and Application Scenarios
This medium is widely used by:
- Clinical microbiologists in hospital laboratories
- Infection control teams screening for S. aureus carriers
- Food safety and quality-assurance laboratories
- Environmental monitoring personnel in pharmaceutical production
- Academic educators and research scientists
Best Practices for Use and Maintenance
Always allow refrigerated plates to warm to room temperature before inoculation to prevent condensation. Avoid stacking plates too high during incubation to ensure proper airflow. Inspect plates for dehydration or contamination before use. Confirm suspicious colonies with confirmatory tests such as coagulase, catalase, or molecular assays. Dispose of all plates and samples as regulated biohazard waste.
Regulatory and Safety Information
BD 211407 Mannitol Salt Agar is intended for in vitro diagnostic use by trained laboratory personnel. Follow appropriate PPE and biosafety level 2 practices when handling clinical specimens. Dispose of used materials in accordance with institutional and regulatory waste-management guidelines.
