BD 231613 - Disk Susceptibility Sensi-Disc Cefoperazone 75mcg Precision AST Disc for Third-Generation Cephalosporin Testing, 10/SP 10/PK
The BD 231613 Disk Susceptibility Sensi-Disc Cefoperazone 75mcg is a high-quality antimicrobial susceptibility testing (AST) disc formulated to assess bacterial sensitivity to cefoperazone, a third-generation cephalosporin known for its broad-spectrum activity against Gram-negative and select Gram-positive pathogens. Each sterile disc contains 75 micrograms of cefoperazone, delivering a standardized antibiotic diffusion gradient for accurate and reproducible results using the Kirby-Bauer disk diffusion method. Manufactured under BDs strict quality systems, this Sensi-Disc ensures consistent potency, diffusion uniformity, and dependable performance across clinical and research laboratories.
Key Benefits
The BD 231613 Cefoperazone 75mcg Sensi-Disc provides clear inhibition zones and stable antibiotic release, enabling precise interpretation of susceptibility patterns. Its sterile, single-use design minimizes contamination risks and enhances workflow efficiency. BDs rigorous lot-to-lot consistency ensures reliable outcomes, supporting clinical decision-making in infections involving resistant or difficult-to-treat Gram-negative organisms.
Compatibility and Applications
This disc is compatible with standard Mueller-Hinton agar and follows CLSI and EUCAST guidelines for disk diffusion AST. It is commonly used to test:
- Pseudomonas aeruginosa
- Escherichia coli
- Klebsiella species
- Enterobacter species
- Other Gram-negative bacilli requiring cephalosporin susceptibility assessment
Cefoperazone is widely used in respiratory, intra-abdominal, urinary tract, and hospital-acquired infections, making the BD 231613 disc valuable for routine diagnostic panels.
Usage Guidelines
Prepare a 0.5 McFarland standard bacterial suspension and inoculate a Mueller-Hinton agar plate evenly. Using sterile forceps or an automated disk dispenser, place the BD 231613 Cefoperazone 75mcg disc onto the agar surface. Incubate at 3537C for 1620 hours. Measure inhibition zones and interpret results using the most current CLSI or EUCAST breakpoints. Store discs at 28C in sealed containers with desiccants to maintain potency and prevent moisture exposure.
Certifications, Safety Standards, and Regulatory Approvals
The BD 231613 Sensi-Disc is manufactured in ISO 9001 and ISO 13485 certified facilities and complies with FDA and CE requirements for in vitro diagnostic (IVD) devices. Each lot undergoes comprehensive testing for antibiotic content, diffusion uniformity, sterility, and stability, ensuring reliable performance aligned with international AST standards.
Comparison with Competitor Products
BD Sensi-Discs are recognized for superior consistency, sharper diffusion zones, and enhanced potency stability when compared with generic susceptibility discs. Competitor discs may exhibit uneven antibiotic loading or unpredictable diffusion patterns, potentially impacting clinical interpretation. BDs controlled manufacturing process ensures dependable results essential for critical antimicrobial testing.
Typical User Profile and Application Scenarios
This cefoperazone AST disc is commonly used by clinical microbiologists, diagnostic laboratory technologists, infectious disease teams, and research scientists. Ideal applications include:
- Routine AST panels in hospital and reference labs
- Resistance monitoring in Gram-negative organisms
- Research involving cephalosporin activity and resistance mechanisms
- Quality-control programs for diagnostic testing
Best Practices for Use and Maintenance
Handle discs using sterile forceps to avoid contamination. Allow refrigerated discs to reach room temperature before opening to prevent condensation. Verify performance with appropriate QC organisms such as E. coli ATCC 25922 and Pseudomonas aeruginosa ATCC 27853. Do not use expired or damaged discs, as reduced potency may affect zone diameters. Dispose of all used materials as biohazard waste following institutional protocols.
Regulatory and Safety Information
The BD 231613 Cefoperazone 75mcg Sensi-Disc is intended for in vitro diagnostic use by trained laboratory personnel. Always follow biosafety level 2 guidelines when handling clinical isolates. Use appropriate PPEgloves, lab coat, and safety eyewearand discard all contaminated materials according to regulatory and institutional waste procedures.
