BD 231619 - Ticarcillin Sensi-Disc Reliable Antimicrobial Susceptibility Testing Disc for Penicillin-Class Antibiotics, 10/BX
The BD 231619 Ticarcillin Sensi-Disc is a high-quality antimicrobial susceptibility testing (AST) disc designed for evaluating bacterial response to ticarcillin, a broad-spectrum carboxypenicillin antibiotic. Engineered for use in Kirby-Bauer disk diffusion methods, each sterile, single-use disc delivers a consistent antibiotic concentration to ensure accurate, reproducible zone-of-inhibition results. BDs precise manufacturing supports dependable clinical decision-making and reliable detection of beta-lactam susceptibilities in key Gram-negative pathogens.

Key Benefits
This ticarcillin Sensi-Disc provides sharp, well-defined diffusion zones that enhance reading accuracy. Its sterile format minimizes contamination risk and supports smooth laboratory workflow. BDs stringent lot-to-lot consistency ensures stable potency and uniform antibiotic distribution, improving overall test reliabilityespecially when evaluating resistance patterns in high-impact hospital pathogens.
Compatibility and Applications
The BD 231619 disc is compatible with Mueller-Hinton agar following CLSI and EUCAST guidelines. It is commonly used for susceptibility testing of:
- Pseudomonas aeruginosa
- Escherichia coli
- Proteus species
- Klebsiella and Enterobacter species
- Other Gram-negative organisms where carboxypenicillins are relevant
Ticarcillin susceptibility testing is important in respiratory, urinary, bloodstream, and intra-abdominal infection workups, especially in antimicrobial stewardship programs.
Usage Guidelines
Prepare a standardized 0.5 McFarland bacterial suspension and inoculate Mueller-Hinton agar evenly. Apply the BD Sensi-Disc using sterile forceps or an approved disc dispenser. Incubate plates at 3537C for 1620 hours. Measure inhibition zone diameters and interpret using the current CLSI or EUCAST breakpoint tables. Store discs at 28C with desiccant protection, and avoid unnecessary exposure to humidity.
Certifications, Safety Standards, and Regulatory Approvals
This Sensi-Disc is produced in ISO 9001 and ISO 13485 certified facilities. It complies with FDA and CE requirements for in vitro diagnostic (IVD) materials and undergoes rigorous testing for potency, diffusion uniformity, sterility, and stability.
Comparison with Competitor Products
BD Sensi-Discs deliver superior consistency and reliability compared with many generic AST discs. Competitor versions may show uneven antibiotic loading, reduced stability, or weaker diffusion gradients, affecting susceptibility accuracy. BDs high manufacturing precision ensures clear, reproducible inhibition zonesmaking it a preferred choice for clinical microbiology labs.
Typical User Profile and Application Scenarios
The BD 231619 Ticarcillin Sensi-Disc is widely used by:
- Clinical microbiology laboratories
- Hospital diagnostic departments
- Public health and reference labs
- Academic and research institutions studying beta-lactam resistance
Best Practices for Use and Maintenance
Allow discs to equilibrate to room temperature before opening to avoid condensation. Handle discs with sterile forceps and limit exposure to ambient moisture. Use validated QC strainssuch as E. coli ATCC 25922 and P. aeruginosa ATCC 27853to confirm performance accuracy. Dispose of used discs and plates in accordance with institutional biohazard protocols.
Regulatory and Safety Information
For in vitro diagnostic use only. This product must be used by trained laboratory professionals following biosafety level 2 procedures. Wear appropriate PPE and follow all institutional and regulatory guidelines for disposal of biohazard materials.
