Thermo Scientific™ Oxoid™ Aztreonam ATM Antimicrobial Susceptibility discs, 30 µg

Thermo Scientific™ Oxoid™ Aztreonam Antimicrobial Susceptibility Discs are high-performance paper discs impregnated with 30 µg of aztreonam, designed for standardized disk diffusion testing in microbiology laboratories. These discs support the manual determination of antimicrobial susceptibility profiles for Gram-negative bacteria using the Kirby-Bauer method on agar media.

Aztreonam is a monobactam β-lactam antibiotic effective primarily against aerobic Gram-negative bacteria, including Pseudomonas aeruginosa. It is particularly valuable in resistance surveillance, infection diagnosis, and antimicrobial stewardship programs in clinical and veterinary microbiology.

Key Features & Benefits

• Reliable Performance: Delivers accurate, reproducible zone diameters for clinical interpretation of resistance and susceptibility.
• Pharmacopoeia Compliance: Meets CLSI, EUCAST, DIN, BSAC, and SFM guideline requirements for AST.
• Ease-of-Use: Features shatterproof, spring-loaded cartridges with clear labeling and end-of-cartridge indicators.
• Optimized Stability: Each cartridge is individually foil-sealed with desiccant to maintain <2% moisture content and ensure extended shelf life and performance consistency.
• Visual Interpretation: Allows detection of additional phenomena such as resistant mutants, beta-lactamase production, and synergy or antagonism between antibiotics.

Typical Applications

• Clinical Microbiology: AST testing of Escherichia coli, Klebsiella spp., Pseudomonas aeruginosa, and other Gram-negative pathogens.
• Infection Control: Surveillance of monobactam susceptibility in hospital and community-acquired infections.
• Research & Public Health: Resistance monitoring and investigation of treatment efficacy in drug development.
