BD 231268 - Bacitracin Sensi-Disc Reliable Antimicrobial Susceptibility Testing for Gram-Positive Bacteria

BD 231268 - Bacitracin Sensi-Disc Reliable Antimicrobial Susceptibility Testing for Gram-Positive Bacteria

The BD 231268 Bacitracin Sensi-Disc is a precision-manufactured antibiotic susceptibility testing reagent designed to evaluate bacterial sensitivity to bacitracin. Each sterile paper disk is impregnated with a standardized concentration of bacitracin, a polypeptide antibiotic primarily effective against Gram-positive organisms. Used in clinical microbiology laboratories for routine diagnostic testing, this Sensi-Disc enables accurate identification and differentiation of bacterial species, such as distinguishing Streptococcus pyogenes (Group A Streptococci) from other beta-hemolytic streptococci, aiding in prompt and accurate infection diagnosis.

Key Benefits

The BD 231268 Bacitracin Sensi-Disc delivers consistent, reproducible performance in antimicrobial susceptibility testing. Each disk contains a precisely controlled antibiotic concentration to ensure uniform diffusion and accurate inhibition zone formation. The sterile, single-use design minimizes contamination risk, ensuring reliable and hygienic handling. With BDs stringent quality manufacturing standards, laboratories benefit from dependable test outcomes that enhance diagnostic accuracy and clinical decision-making for antimicrobial therapy.

Compatibility and Applications

The BD 231268 Bacitracin Sensi-Disc is compatible with standard Mueller-Hinton agar or blood agar plates and is used in the disk diffusion method for antimicrobial susceptibility testing. It is particularly valuable for identifying Group A Streptococcus species based on their characteristic sensitivity to bacitracin. The product is commonly used in hospital microbiology laboratories, reference labs, and research institutions for routine bacterial screening and species differentiation.

Usage Guidelines

Follow aseptic laboratory techniques when using the BD 231268 Sensi-Disc. Inoculate the agar plate with a standardized bacterial suspension, then place the bacitracin disk onto the surface using sterile forceps or a disk dispenser. Incubate the plate under suitable temperature and atmospheric conditions, typically 3537C for 1824 hours. Following incubation, measure the diameter of the inhibition zone around the disk to determine bacterial sensitivity. Always compare results against CLSI (Clinical and Laboratory Standards Institute) or EUCAST interpretive guidelines.

Certifications, Safety Standards, and Regulatory Approvals

The BD 231268 Bacitracin Sensi-Disc is manufactured under ISO 9001 and ISO 13485 certified quality systems. It complies with FDA regulations and international standards for antimicrobial susceptibility testing materials. Each lot is validated for potency, uniformity, and sterility to ensure compliance with CLSI performance standards, providing confidence in every test performed.

Comparison with Competitor Products

Compared to generic antibiotic disks, BD Sensi-Discs offer superior precision, potency consistency, and extended shelf life. Competitor disks often exhibit variability in antibiotic content or diffusion rates, leading to inconsistent inhibition zones. BDs proprietary manufacturing process ensures each disk contains an exact, uniform amount of bacitracin, resulting in highly reproducible results across laboratories. Its protective packaging further safeguards against humidity and temperature variations, ensuring optimal disk integrity until use.

Typical User Profile and Application Scenarios

The BD 231268 Bacitracin Sensi-Disc is ideal for use by clinical microbiologists, laboratory technologists, and infection control specialists. It is commonly employed in hospital diagnostic laboratories, public health facilities, and research centers for bacterial identification and sensitivity testing. Typical applications include screening throat swabs for Group A Streptococcus infections and monitoring bacterial susceptibility trends in clinical samples.

Best Practices for Use and Maintenance

Store the disks in a sealed container at 28C and protect them from moisture and direct light to maintain antibiotic potency. Before use, allow refrigerated disks to reach room temperature to prevent condensation. Handle all materials using sterile forceps and dispose of used disks and plates as biohazard waste. Regularly verify test performance using quality control strains as recommended by CLSI guidelines to ensure ongoing reliability and compliance.

Regulatory and Safety Information

The BD 231268 Bacitracin Sensi-Disc is an in vitro diagnostic device intended for professional laboratory use only. It complies with applicable FDA and CE regulatory standards for susceptibility testing reagents. The disks are non-toxic but should be handled in accordance with biosafety protocols, particularly when used with potentially infectious bacterial cultures. Appropriate personal protective equipment (PPE) such as gloves and lab coats should always be worn during handling and disposal.
