BD 231632 - Sensi-Disc Ceftazidime 30g Reliable Antimicrobial Susceptibility Testing Disc for Gram-Negative Bacteria,EA

The BD 231632 Sensi-Disc Ceftazidime 30g is a precision-manufactured antimicrobial susceptibility testing (AST) disc used in standardized disk diffusion assays, such as the Kirby-Bauer method. Produced by BD (Becton Dickinson), this disc contains 30 micrograms of ceftazidime, a third-generation cephalosporin antibiotic known for its effectiveness against a broad range of Gram-negative bacteria, including Pseudomonas aeruginosa and Enterobacteriaceae. The BD Sensi-Disc line is globally recognized for its superior quality control, accuracy, and consistency in determining bacterial resistance profiles, making it an essential tool in clinical and microbiological diagnostics.

Key Benefits

The BD Sensi-Disc Ceftazidime 30g ensures accurate and reproducible results by delivering uniform antibiotic diffusion and potency across every batch. Its high-purity antibiotic formulation guarantees consistent zone diameters, supporting reliable clinical interpretations based on CLSI (Clinical and Laboratory Standards Institute) or EUCAST guidelines. Packaged in moisture-resistant cartridges, the discs maintain stability and potency throughout their shelf life. BDs precision manufacturing minimizes variability, ensuring dependable antimicrobial susceptibility testing for critical infection control and patient management decisions.

Compatibility and Applications

The BD 231632 Sensi-Disc Ceftazidime 30g is fully compatible with standard Mueller-Hinton Agar (MHA) and used in Kirby-Bauer disk diffusion testing. It is specifically designed to evaluate the susceptibility of Gram-negative pathogens, including Pseudomonas aeruginosa, Klebsiella spp., Enterobacter spp., Escherichia coli, and other members of the Enterobacteriaceae family. The disc is widely utilized in hospital microbiology laboratories, research institutions, and public health centers for resistance profiling, antibiotic therapy selection, and epidemiological surveillance of multidrug-resistant organisms.

Usage Guidelines

Prepare a standardized bacterial suspension equivalent to a 0.5 McFarland turbidity standard and inoculate evenly onto a Mueller-Hinton Agar plate. Using sterile forceps or a BD Sensi-Disc dispenser, place the BD Ceftazidime 30g disc on the agar surface. Incubate the plate at 352C for 1618 hours in ambient air. Measure the diameter of the inhibition zone in millimeters and interpret according to CLSI or EUCAST interpretive tables. Include control strains, such as Escherichia coli ATCC 25922 and Pseudomonas aeruginosa ATCC 27853, to validate test accuracy and consistency.

Certifications, Safety Standards, and Regulatory Approvals

The BD 231632 Sensi-Disc Ceftazidime 30g meets ISO 13485 and ISO 9001 quality management standards and complies with FDA and CE regulations for in vitro diagnostic (IVD) use. It is produced under Good Manufacturing Practices (GMP) and validated according to CLSI M100 standards. Each batch is tested for antibiotic potency, diffusion consistency, and sterility to ensure compliance with international quality and performance benchmarks. BDs rigorous quality assurance guarantees consistent, reliable diagnostic outcomes for clinical and research laboratories worldwide.

Comparison with Competitor Products

Compared to competitor AST discs, BD Sensi-Discs offer unmatched reproducibility, stability, and manufacturing precision. Some competitor products may exhibit variable antibiotic loading or inconsistent diffusion patterns, leading to unreliable zone interpretations. BDs proprietary production and moisture-resistant packaging preserve the antibiotic activity, preventing degradation from humidity or temperature fluctuations. Laboratories prefer BD Sensi-Discs for their long-term reliability, precise performance, and compatibility with standardized antimicrobial susceptibility testing protocols.

Typical User Profile and Application Scenarios

This product is intended for use by clinical microbiologists, laboratory technologists, and research scientists engaged in antimicrobial susceptibility testing. It is used in diagnostic laboratories, hospital microbiology departments, and pharmaceutical quality control settings to assess bacterial resistance patterns and guide treatment decisions. The BD 231632 Ceftazidime 30g disc is particularly valuable in detecting cephalosporin-resistant Gram-negative bacteria and monitoring resistance trends in healthcare and community environments.

Best Practices for Use and Maintenance

Store BD Sensi-Disc vials or cartridges at 28C in a tightly closed container to maintain potency. Before use, allow discs to reach room temperature (2025C) to prevent condensation. Handle discs with sterile forceps or an automatic dispenser to avoid contamination. Always use freshly prepared Mueller-Hinton Agar plates of uniform thickness (approximately 4mm) and pH (7.27.4). Dispose of used discs and culture materials as biohazardous waste in compliance with institutional biosafety procedures. Regularly verify disc potency with control organisms to ensure consistent and reliable results.

Regulatory and Safety Information

This product is intended for professional laboratory use only. Handle bacterial isolates under Biosafety Level 2 (BSL-2) containment. Wear appropriate personal protective equipment (PPE), including gloves, lab coats, and eye protection, when handling cultures and reagents. Avoid direct contact with bacterial samples or contaminated surfaces. Dispose of all waste materials following institutional and regulatory biosafety guidelines. Refer to the Safety Data Sheet (SDS) for detailed handling, storage, and safety information. BD ensures compliance with international safety and environmental standards for laboratory reagents and consumables.
