Thermo Scientific™ Oxoid™ Nalidixic Acid Antimicrobial Susceptibility Discs are high-quality, ready-to-use paper discs designed for manual antimicrobial susceptibility testing (AST) via the standardized disk diffusion method. Containing 30 µg of nalidixic acid per disc, these cartridges are used to determine the susceptibility profiles of Gram-negative organisms, particularly members of the Enterobacteriaceae family, to the first-generation quinolone nalidixic acid.
These discs are ideally suited for clinical microbiology, surveillance of antimicrobial resistance (AMR), and infection control programs. They comply with CLSI, EUCAST, BSAC, and SFM guidelines, ensuring robust, reproducible results for both diagnostic and quality control purposes.
Key Features & Benefits
- Accurate and Reliable: Delivers standardized zone diameters for reliable interpretation of bacterial susceptibility.
- Pharmacopoeia Compliance: Conforms to leading global AST guidelines (CLSI, EUCAST, BSAC, SFM).
- Ease-of-Use: Provided in shatterproof, spring-loaded cartridges with clearly marked labels and end-of-cartridge indicators.
- Enhanced Stability: Each cartridge is individually sealed with desiccant to maintain moisture levels below 2%, preserving disc potency and shelf life.
- Broad Application: Effective in detecting nalidixic acid susceptibility and resistance in urinary pathogens and enteric bacteria.
Typical Applications
- Clinical Diagnostics: AST for E. coli, Shigella, Salmonella, Proteus, and other Gram-negative bacilli.
- Public Health Surveillance: Monitoring quinolone resistance trends in community-acquired and hospital-acquired infections.
- Veterinary & Food Safety Testing: Identifying resistant strains in animal-derived or foodborne samples.
