Key Benefits
This erythromycin Sensi-Disc provides clear and uniform inhibition zones, enhancing interpretive accuracy for macrolide susceptibility. BDs precision manufacturing ensures consistent antibiotic potency and stable diffusion characteristics across all discs. The cartridge format minimizes handling time, reduces contamination risk, and improves operational efficiency in high-volume testing environments. Its dependable performance supports confident identification of resistant strains, including MLSB phenotype organisms.
Compatibility and Applications
The BD 230793 disc is compatible with standard Mueller-Hinton agar following CLSI and EUCAST guidelines. It is commonly used to test susceptibility in:
- Streptococcus pyogenes
- Streptococcus pneumoniae (with modified methods)
- Staphylococcus aureus and coagulase-negative staphylococci
- Select Gram-negative organisms where macrolide testing is indicated
Erythromycin susceptibility results are essential in respiratory, skin and soft-tissue, and systemic infection management, particularly in settings where macrolides serve as first-line or alternative therapies.
Usage Guidelines
Prepare a 0.5 McFarland standard bacterial suspension and inoculate Mueller-Hinton agar evenly. Load the BD cartridge into a compatible disc dispenser or remove discs with sterile forceps. Apply discs to the agar surface and incubate at 3537C for 1620 hours. Measure the zone of inhibition and interpret results using current CLSI or EUCAST breakpoint criteria. Store at 28C with desiccant protection, avoiding exposure to moisture.
Certifications, Safety Standards, and Regulatory Approvals
The BD 230793 Sensi-Disc is manufactured under ISO 9001 and ISO 13485 certified quality systems. It meets FDA and CE regulatory requirements for in vitro diagnostic (IVD) applications. Each lot is tested for antibiotic potency, sterility, diffusion uniformity, and long-term stability.
Comparison with Competitor Products
BD Sensi-Discs are widely recognized for superior reliability, consistent antibiotic content, and predictably sharp inhibition zones. Many generic discs exhibit variable diffusion or unstable antibiotic loading, which can compromise AST accuracy. BDs advanced manufacturing and QC processes ensure dependable macrolide susceptibility results every time.
Typical User Profile and Application Scenarios
This product is extensively used by:
- Clinical microbiology and hospital diagnostic laboratories
- Public health and reference laboratories monitoring macrolide resistance
- Teaching and training programs demonstrating disk diffusion methods
- Research labs studying antimicrobial resistance patterns
Best Practices for Use and Maintenance
Allow discs to reach room temperature before opening to prevent moisture condensation. Handle discs with sterile forceps and avoid prolonged exposure to air. Use approved QC strainssuch as Staphylococcus aureus ATCC 25923to validate test performance. Follow strict aseptic technique, and dispose of expired discs or moisture-compromised cartridges appropriately.
Regulatory and Safety Information
For in vitro diagnostic use only. The product should be handled by trained laboratory personnel following biosafety level 2 guidelines. Dispose of used discs, plates, and bacterial materials as regulated biohazard waste.
