Key Benefits
The BD 231751 Ceftazidime 30/10mcg Sensi-Disc ensures exceptional reproducibility and precision in antimicrobial susceptibility testing. The dual-strength format provides differential readings for ESBL confirmation and broader beta-lactam resistance profiling. Each disk is impregnated with exact antibiotic concentrations to ensure consistent diffusion and clear inhibition zones. The sterile, single-use design eliminates cross-contamination risks, ensuring dependable and accurate results. By delivering standardized and reproducible outcomes, BDs Sensi-Discs enhance laboratory efficiency and support clinicians in selecting the most effective antimicrobial therapy.
Compatibility and Applications
The BD 231751 Sensi-Disc is compatible with standard Mueller-Hinton agar and conforms to CLSI (Clinical and Laboratory Standards Institute) and EUCAST (European Committee on Antimicrobial Susceptibility Testing) guidelines. It is widely used for susceptibility testing of Gram-negative bacteria, including Escherichia coli, Klebsiella pneumoniae, Enterobacter spp., and Pseudomonas aeruginosa. This disk is an essential diagnostic tool for detecting ESBL and AmpC beta-lactamase-producing strains in hospital laboratories, reference centers, and public health facilities.
Usage Guidelines
Use the BD 231751 Ceftazidime 30/10mcg Sensi-Disc in accordance with CLSI-recommended disk diffusion procedures. Prepare a standardized bacterial inoculum equivalent to a 0.5 McFarland standard and spread evenly over a Mueller-Hinton agar plate. Place the disk aseptically on the inoculated surface using sterile forceps or an automatic dispenser. Incubate at 3537C for 1618 hours. Measure the inhibition zones around each disk and interpret results based on established CLSI or EUCAST standards. Store disks at 28C in a dry, dark place and allow them to reach room temperature before use to prevent condensation.
Certifications, Safety Standards, and Regulatory Approvals
The BD 231751 Ceftazidime 30/10mcg Sensi-Disc is manufactured under ISO 9001 and ISO 13485 certified quality management systems. It complies with FDA and CE requirements for in vitro diagnostic (IVD) medical devices. Each production lot is tested for potency, diffusion consistency, and sterility to ensure reliability and adherence to global quality benchmarks. BDs reputation for precision manufacturing ensures every disk meets stringent laboratory testing standards.
Comparison with Competitor Products
Compared to generic antibiotic disks, BD Sensi-Discs offer superior reproducibility, stability, and precision. Many competitor disks may show inconsistent antibiotic concentration or diffusion variability, leading to uncertain interpretations. BDs proprietary manufacturing process guarantees uniform antibiotic loading, consistent diffusion profiles, and reliable inhibition zones. The result is standardized accuracy and longer shelf stability, giving BDs Sensi-Discs a clear advantage in clinical performance and laboratory reliability.
Typical User Profile and Application Scenarios
The BD 231751 Ceftazidime 30/10mcg Sensi-Disc is used by clinical microbiologists, laboratory technologists, and infection control professionals. It is ideal for hospital diagnostic laboratories, pharmaceutical quality control units, and public health organizations involved in antimicrobial resistance monitoring. This disk is essential for detecting beta-lactamase-mediated resistance and for routine antimicrobial profiling of Gram-negative bacteria, guiding appropriate antibiotic selection in patient care.
Best Practices for Use and Maintenance
Handle Sensi-Discs with sterile tools and aseptic technique to prevent contamination. Always allow refrigerated disks to reach ambient temperature before use to avoid moisture-related degradation. Use appropriate control organisms such as Escherichia coli ATCC 25922 and Klebsiella pneumoniae ATCC 700603 to verify test accuracy. Avoid exposure to excessive humidity or heat. After use, dispose of all disks and culture plates following institutional biohazard waste management procedures.
Regulatory and Safety Information
The BD 231751 Ceftazidime 30/10mcg Sensi-Disc is intended for in vitro diagnostic use by trained laboratory professionals. It complies with FDA, CE, and ISO regulations for microbiological testing reagents. While non-toxic under normal conditions, the disks should be handled following biosafety level 2 (BSL-2) laboratory practices when testing pathogenic bacterial isolates. Use appropriate personal protective equipment (PPE) including gloves and lab coats when performing tests.
