BD 231731 - TAXO R VX Factor Discs Essential Growth Factors for Haemophilus Identification
The BD 231731 TAXO R VX Factor Discs provide standardized V (NAD) and X (hemin) growth factors required for differentiating and identifying Haemophilus species. Designed for use in clinical microbiology laboratories, these discs deliver precise amounts of essential factors to support the interpretation of satellitism, growth-dependency patterns, and species-level differentiation. Manufactured to BDs high-quality standards, TAXO VX discs ensure consistent diffusion, reliable growth enhancement, and clear diagnostic results.

Key Benefits
These TAXO VX discs supply dependable and uniform concentrations of V and X factors, ensuring predictable growth reactions. Their sterile, single-use format prevents contamination and maintains test accuracy. BDs rigorous quality control guarantees consistent performance, helping microbiologists quickly differentiate species such as H. influenzae, H. parainfluenzae, and H. ducreyi with high diagnostic reliability.
Compatibility and Applications
BD TAXO VX discs are compatible with chocolate agar, Mueller-Hinton agar supplemented as required, and other media used for Haemophilus identification. They are commonly used for:
- X and V factor dependency testing
- Differentiation of Haemophilus species based on growth patterns
- Diagnostic workflows in respiratory and invasive infection testing
- Teaching laboratories demonstrating factor requirements
Representative growth reactions include:
- H. influenzae requires both X and V factors
- H. parainfluenzae requires V factor only
- H. ducreyi requires X factor only
Usage Guidelines
Prepare an inoculated plate using standardized bacterial suspension. Place the BD TAXO R VX Factor Disc on the agar surface with sterile forceps. Incubate at 3537C for 1824 hours in a CO2-enriched environment, depending on the organisms requirements. Observe patterns of growth around each factor zone to determine dependency and species identification. Store discs at 28C in sealed, desiccated packaging to preserve potency.
Certifications, Safety Standards, and Regulatory Approvals
BD TAXO VX discs are manufactured under ISO 9001 and ISO 13485 certified systems and meet FDA and CE requirements for in vitro diagnostic (IVD) use. Each batch is tested for factor potency, sterility, diffusion accuracy, and shelf-life stability to ensure high diagnostic consistency.
Comparison with Competitor Products
Compared with generic VX factor discs, BD TAXO discs provide more reliable diffusion gradients and superior lot-to-lot consistency. Competitor brands may yield weaker factor release or unstable performance, leading to ambiguous growth patterns. BDs manufacturing precision ensures accurate species differentiation and trusted results in clinical diagnostics.
Typical User Profile and Application Scenarios
These discs are ideal for:
- Clinical microbiologists identifying respiratory pathogens
- Hospital diagnostic laboratories handling invasive Haemophilus infections
- Public health laboratories during outbreak investigations
- Academic and teaching laboratories demonstrating factor dependency
Best Practices for Use and Maintenance
Allow discs to reach room temperature before use to avoid moisture condensation. Handle only with sterile forceps and minimize exposure to ambient humidity. Use appropriate QC organisms such as H. influenzae ATCC 10211 to verify correctness. Discard expired or compromised discs immediately and follow biohazard protocols for disposal.
Regulatory and Safety Information
The BD 231731 TAXO R VX Factor Disc is intended for in vitro diagnostic use by trained laboratory professionals. Follow biosafety level 2 precautions when handling Haemophilus species or clinical specimens. Wear appropriate PPE and dispose of plates and discs in regulated biohazard waste.
