BD 227761 - Shigella Antiserum Poly Group High-Specificity Reagent for Serogroup Identification
The BD 227761 Shigella Antiserum Poly Group is a high-quality polyvalent antiserum designed for rapid and accurate serogroup identification of Shigella species. This reagent provides strong, distinct agglutination reactions essential for confirming group-level classification in clinical microbiology, public health testing, and epidemiological investigations. Manufactured under strict BD quality standards, the polyvalent formulation ensures broad coverage across major Shigella serogroups, making it a dependable first-line screening tool before applying monovalent antisera.
Key Benefits
The polyvalent antiserum enables quick differentiation of Shigella isolates through clear, easy-to-read agglutination patterns. Its broad reactivity reduces testing time by eliminating the need to screen each group individually at the initial stage. BDs highly standardized production ensures excellent specificity, minimized cross-reactivity, and strong lot-to-lot consistency, supporting confident, reproducible results.
Compatibility and Applications
BD Shigella Poly Group Antiserum is compatible with:
- Standard slide and tube agglutination methods
- Pure cultures grown on non-inhibitory media
- Common workflows in enteric pathogen identification
Primary application scenarios include:
- Clinical stool culture confirmation
- Public health surveillance of dysentery outbreaks
- Serogroup screening before monovalent antisera testing
- Environmental and food microbiology investigations
- Academic research on enteric pathogens
Usage Guidelines
Prepare a smooth saline suspension of the suspect colony. Place a drop of the BD Shigella Poly Group antiserum onto a clean slide, mix gently with the suspension, and observe for agglutination within the recommended timeframe. Always perform parallel negative control testing. Store the antiserum at 28C and avoid freezing. Discard reagent if signs of contamination or discoloration appear.
Certifications, Safety Standards, and Regulatory Approvals
BD antisera are manufactured in ISO 9001 and ISO 13485 certified facilities. The reagent complies with FDA and CE requirements for in vitro diagnostic (IVD) use. Each lot undergoes comprehensive QC testing for potency, specificity, sterility, and stability.
Comparison with Competitor Products
Compared with generic polyvalent antisera, BD formulations offer enhanced clarity of agglutination, superior specificity, and reduced cross-reactivity with non-target enteric organisms. Competitor reagents may produce weaker reactions or inconsistent group identification. BDs stringent quality controls and validated performance make it a preferred choice for laboratories requiring dependable screening tools.
Typical User Profile and Application Scenarios
This antiserum is widely used by:
- Clinical microbiologists
- Public health and epidemiology labs
- Environmental and food safety laboratories
- Academic research programs studying enteric diseases
- Diagnostic laboratories handling routine stool cultures
Best Practices for Use and Maintenance
Allow the reagent to reach room temperature before use. Use clean, dry slides and fresh saline suspensions. Read reactions promptly within the recommended window to avoid misinterpretation. Keep vials tightly capped to prevent contamination. Rotate stock to use the earliest expiring material first.
Regulatory and Safety Information
For in vitro diagnostic use only. Handle all clinical isolates under biosafety level 2 precautions. Wear PPE when performing tests and dispose of contaminated materials in accordance with institutional biohazard protocols.
