BD 228341 - Shigella Anti Group A Antiserum High-Specificity Reagent for Serological Identification

BD 228341 - Shigella Anti Group A Antiserum High-Specificity Reagent for Serological Identification

The BD 228341 Shigella Anti Group A Antiserum is a high-quality serological reagent formulated for the rapid and accurate identification of Shigella Group A isolates. Manufactured to BDs strict quality standards, this antiserum provides reliable agglutination reactions for confirming group-level classification in clinical microbiology laboratories. Its well-characterized antibody formulation supports dependable results in stool culture workups, outbreak investigations, and routine enteric pathogen identification.

Key Benefits

This antiserum delivers strong, specific agglutination with reduced cross-reactivity, enabling clear interpretation of Group A Shigella strains. The sterile, ready-to-use liquid format enhances workflow efficiency, while BDs rigorous lot consistency ensures reproducible performance across testing runs. Its high sensitivity and specificity make it an essential confirmatory reagent for laboratories processing enteric samples.

Compatibility and Applications

BD 228341 is designed for slide or tube agglutination procedures commonly used in:

• Enteric bacteriology workups
• Stool culture pathogen confirmation
• Public health and epidemiologic surveillance
• Clinical laboratories differentiating Shigella species

It is compatible with standard saline suspensions, culture media, and identification workflows used for Gram-negative enteric pathogens.

Usage Guidelines

Emulsify a suspected colony in saline to create a smooth suspension. Add one drop of the BD Anti Group A Antiserum and gently mix on a clean glass slide. Observe for visible agglutination within the recommended timeframe. Always perform controls in parallel. Store the vial refrigerated at 28C and avoid freezing. Do not use if the reagent shows discoloration, contamination, or expired dating.

Certifications, Safety Standards, and Regulatory Approvals

The BD Shigella Anti Group A antiserum is manufactured under ISO 9001 and ISO 13485 certified quality systems. It complies with FDA and CE requirements for in vitro diagnostic (IVD) reagents. Each lot undergoes potency, sterility, specificity, and stability testing to ensure diagnostic accuracy.

Comparison with Competitor Products

Compared with generic antisera, BD formulations offer superior specificity and reduced false-positive reactions. Competitor reagents may exhibit broader cross-reactivity or weaker agglutination patterns, leading to ambiguous results. BDs robust QC process ensures clearer reactivity and more consistent identification of Group A Shigella isolates.

Typical User Profile and Application Scenarios

This reagent is commonly used by:

• Clinical microbiology laboratories processing stool cultures
• Hospital infection control units
• Public health and reference laboratories
• Academic and teaching laboratories studying enteric pathogens

Best Practices for Use and Maintenance

Bring the reagent to room temperature before testing. Always use clean slides, applicators, and saline to avoid false reactions. Confirm questionable results with control strains. Store reagent upright at recommended temperature and protect from excessive light exposure. Discard immediately if contamination is suspected.

Regulatory and Safety Information

For in vitro diagnostic use only. Handle all clinical samples and reagents using biosafety level 2 precautions. Wear appropriate PPE, and dispose of used slides, pipettes, and biological waste according to institutional biohazard protocols.
