Thermo Scientific™ Oxoid™ Cefotaxime CTX Antimicrobial Susceptibility Discs

Thermo Scientific™ Oxoid™ Cefotaxime Antimicrobial Susceptibility Discs are precision-formulated disc diffusion AST reagents used to evaluate bacterial susceptibility to Cefotaxime, a third-generation cephalosporin. These discs are suitable for manual Antimicrobial Susceptibility Testing (AST) using the Kirby-Bauer agar diffusion method.

Packaged in shatterproof, spring-loaded cartridges and individually sealed with desiccant (<2% moisture), these discs are designed for high accuracy, long shelf life, and ease of handling. They support quantitative assessment of microbial resistance, identification of resistant mutants, and detection of beta-lactamase activity or synergy between antibiotics.

Key Features and Benefits

• Validated for Global Standards: Complies with CLSI, EUCAST, BSAC, DIN, and SFM guidelines
• High Disc Integrity: Individually sealed cartridges protect against humidity and contamination
• Multiple Potencies Available: Choose between 5 µg or 30 µg disc formats depending on testing needs
• Precision Dispensing: Spring-loaded cartridges enable consistent disc placement
• Reliable Test Results: Delivers clear and reproducible inhibition zones
• Flexible Use: Ideal for clinical laboratories conducting resistance monitoring, therapy selection, or antibiotic efficacy screening

Intended Use

Oxoid Cefotaxime AST discs are intended for use in semi-quantitative in vitro diagnostic workflows to assess susceptibility of microorganisms to Cefotaxime, both clinically and in vitro. These discs must be used with pure, agar-grown bacterial cultures, and are designed for professional use only in microbiology labs.

Applications

• AST of Gram-negative organisms (e.g., Enterobacteriaceae, Pseudomonas spp.)
• Screening for ESBL-producing bacteria
• Therapy guidance for urinary, respiratory, and systemic infections
• Phenotypic confirmation of cefotaxime resistance
• Routine diagnostic microbiology and antimicrobial stewardship programs

Thermo Scientific™ Oxoid™ Cefotaxime Antimicrobial Susceptibility Discs are a trusted choice for clinical laboratories performing routine or specialized AST. With validated performance, convenient cartridge format, and availability in multiple concentrations, they support precise evaluation of bacterial susceptibility to Cefotaxime, enabling clinicians to make informed treatment decisions.
