BD 231313 - Sensi-Disc Neomycin Antimicrobial Susceptibility Testing Disc for Accurate Neomycin Sensitivity Profiling
The BD 231313 Sensi-Disc Neomycin is a high-quality antimicrobial susceptibility testing (AST) reagent designed for determining bacterial sensitivity to neomycin, an aminoglycoside antibiotic frequently used in topical formulations and specific infection management. Each sterile Sensi-Disc contains a standardized concentration of neomycin to ensure consistent diffusion in Mueller-Hinton agar for Kirby-Bauer disk diffusion testing. Manufactured under strict BD quality controls, this disc provides laboratories with reliable, reproducible inhibition zones essential for accurate susceptibility interpretation.
Key Benefits
The BD 231313 Neomycin Sensi-Disc delivers dependable potency, uniform diffusion, and clear zone formation, enabling clinicians to accurately evaluate neomycin activity against target organisms. Its sterile, single-use format minimizes contamination and supports consistent performance across high-volume diagnostic workflows. With BDs trusted manufacturing processes, laboratories can confidently interpret susceptibility results and support evidence-based antimicrobial decisions.
Compatibility and Applications
This Sensi-Disc is compatible with standard Mueller-Hinton agar and follows CLSI and EUCAST disk diffusion guidelines. Neomycin testing is particularly valuable for:
- Staphylococcus species
- Enterococcus species (variable response)
- Enteric Gram-negative bacilli
- Environmental and research isolates requiring aminoglycoside profiling
Neomycin susceptibility assessment plays an important role in:
- Topical antimicrobial regimen selection
- Surveillance of aminoglycoside resistance patterns
- Research applications involving aminoglycoside mechanisms
Usage Guidelines
Prepare a bacterial suspension standardized to a 0.5 McFarland density and inoculate a Mueller-Hinton agar plate evenly. Using sterile forceps or a calibrated disk dispenser, place the BD 231313 Neomycin disc onto the agar surface. Incubate plates at 3537C for 1620 hours. After incubation, measure the inhibition zone diameter and interpret results according to the latest CLSI or EUCAST breakpoints. Store discs at 28C in sealed containers containing desiccants to preserve potency.
Certifications, Safety Standards, and Regulatory Approvals
The BD 231313 Sensi-Disc is produced under ISO 9001 and ISO 13485 certified quality systems and meets FDA and CE regulatory requirements for in vitro diagnostic (IVD) products. Each lot undergoes rigorous quality-control testing for antibiotic content, diffusion uniformity, sterility, and stability to ensure consistent performance in clinical and research laboratories.
Comparison with Competitor Products
Compared with generic susceptibility discs, BD Sensi-Discs offer superior diffusion consistency, improved stability, and higher manufacturing precision. Many competitor neomycin discs may exhibit variable antibiotic loading or inconsistent zone formation, risking inaccurate susceptibility categorization. BDs controlled formulation and moisture-resistant packaging ensure dependable results every time.
Typical User Profile and Application Scenarios
This product is widely used by clinical microbiologists, diagnostic laboratory technicians, infectious disease specialists, and research scientists. It is ideal for:
- Routine susceptibility testing panels
- Aminoglycoside resistance surveillance
- Evaluation of topical antimicrobial effectiveness
- Research environments examining aminoglycoside activity or resistance mechanisms
Best Practices for Use and Maintenance
Handle discs using sterile forceps and allow refrigerated discs to reach room temperature before opening the container. Verify performance using recommended quality-control organisms such as Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922. Never use expired discs or those exposed to moisture, as potency reductions may impair accuracy. Dispose of used testing materials in accordance with institutional biohazard protocols.
Regulatory and Safety Information
The BD 231313 Neomycin Sensi-Disc is intended for in vitro diagnostic use by trained professionals. Work with all bacterial cultures under biosafety level 2 conditions. Use PPE including gloves, lab coat, and eye protection. Dispose of used discs and plates as regulated biohazard waste following institutional and local regulations.
