BD 231721 - Sensi-Disc Quinupristin/Dalfopristin (Synercid) Antimicrobial Susceptibility Testing Disc
The BD 231721 Sensi-Disc Quinupristin/Dalfopristin (Synercid) disc is a high-performance antimicrobial susceptibility testing (AST) reagent designed for precise evaluation of bacterial response to the streptogramin combination quinupristin-dalfopristin. Each disc contains the standardized antibiotic concentration required for accurate diffusion and zone-of-inhibition measurement. Manufactured under BDs rigorous quality controls, this disc ensures consistency, reliable antibiotic potency, and dependable results in clinical microbiology laboratories.
Key Benefits
This Synercid susceptibility disc provides clear, well-defined inhibition zones, supporting accurate interpretation according to CLSI or EUCAST standards. BDs precision manufacturing minimizes variability, ensuring stable diffusion and potency across the products shelf life. The protective cartridge packaging reduces moisture exposure and prevents contamination, maintaining disc integrity until use.
Compatibility and Applications
The BD 231721 Sensi-Disc is compatible with all standard disc diffusion testing workflows, including:
- Mueller Hinton agar plates
- Kirby-Bauer disc diffusion methods
- BD Sensi-Disc dispensers and sterile forceps
It is typically used for organisms where quinupristin-dalfopristin may be considered for treatment, including selected Gram-positive bacteria such as Staphylococcus aureus and Enterococcus faecium.
Usage Guidelines
Prepare a standardized inoculum and spread evenly across a Mueller Hinton agar plate. Place the quinupristin/dalfopristin disc onto the agar surface using sterile forceps or a BD disc dispenser. Incubate under recommended AST conditions. Measure the zone of inhibition and interpret according to current CLSI or EUCAST breakpoint criteria. Keep cartridges sealed when not in use and allow them to reach room temperature before opening.
Certifications, Safety Standards, and Regulatory Approvals
BD Sensi-Disc products are produced under ISO 9001 and ISO 13485 manufacturing standards. The discs meet FDA and CE regulations for in vitro diagnostic (IVD) use. Each lot undergoes rigorous QC testing for potency, diffusion quality, pH stability, and performance with reference control strains.
Comparison with Competitor Products
Compared with generic AST discs, BD Sensi-Discs offer superior potency accuracy, better moisture protection, and more consistent antibiotic diffusion. Competitor discs may show increased lot variability or reduced stability. BDs high-control manufacturing and secure cartridge packaging ensure reproducible AST results across different test runs and laboratory environments.
Typical User Profile and Application Scenarios
This disc is widely used by:
- Clinical microbiology laboratories
- Public health and surveillance labs
- Academic institutions studying antimicrobial resistance
- Diagnostic labs performing routine AST
Best Practices for Use and Maintenance
Store discs in their sealed cartridge at recommended temperatures. Avoid moisture exposure or prolonged light exposure. Use sterile tools for dispensing, and recap the cartridge immediately after retrieving discs. Maintain routine QC testing with approved control organisms to validate ongoing performance. Dispose of used discs and plates following institutional biohazard protocols.
Regulatory and Safety Information
For in vitro diagnostic use only. Handle bacterial isolates using biosafety level 2 precautions. Wear PPE and follow institutional guidelines for culture handling and waste disposal.
