Thermo Scientific™ Oxoid™ Ceftazidime Antimicrobial Susceptibility Discs are precision-formulated paper discs used in manual Antimicrobial Susceptibility Testing (AST) to determine the in vitro activity of ceftazidime, a third-generation cephalosporin antibiotic. These discs are applied using the Kirby-Bauer agar diffusion method to classify bacterial isolates as susceptible, intermediate, or resistant based on inhibition zone diameters.
Packaged in spring-loaded, shatterproof cartridges, each disc is individually sealed and moisture-controlled with desiccant to ensure long-term performance and stability. These discs provide clear and reliable results in both routine diagnostic microbiology and antimicrobial resistance (AMR) surveillance workflows.

Key Features and Benefits
- Validated to International Standards: Complies with DIN, EUCAST, and SFM guidelines
- Accurate Results: Consistent inhibition zone formation for reliable AST interpretation
- Dual Potency Options: Available in 10 µg and 30 µg concentrations to suit various testing needs
- User-Friendly Format: Spring-loaded cartridges simplify handling and reduce contamination risks
- Moisture-Controlled Storage: Individually sealed with desiccant (<2% moisture) for stability
- Visual Assessment Tools: Useful for detecting resistance mechanisms, synergy, and beta-lactamase production
Intended Use
These discs are designed for semi-quantitative agar diffusion testing in microbiological laboratories. They are used to determine bacterial susceptibility to ceftazidime and assist clinicians in selecting appropriate antimicrobial therapy. For use with pure, agar-grown cultures by trained professionals only.
Applications
- Phenotypic testing of Gram-negative bacilli, including Pseudomonas aeruginosa
- Extended-spectrum beta-lactamase (ESBL) detection in Enterobacteriaceae
- AST panels for bloodstream, urinary, and respiratory pathogens
- Hospital antimicrobial stewardship programs
- Public health AMR surveillance laboratories
