Thermo Scientific™ Oxoid™ Cefsulodin Antimicrobial Susceptibility Disks are designed for use in manual antimicrobial susceptibility testing (AST) of microorganisms using the disk diffusion method. Each disc is pre-loaded with 30 µg of Cefsulodin, a third-generation cephalosporin antibiotic effective primarily against Pseudomonas aeruginosa and Yersinia enterocolitica.
These high-quality disks enable accurate classification of bacterial isolates as susceptible, intermediate, or resistant, while also offering a visual indication of additional microbiological phenomena such as resistant mutants, inoculum density, and beta-lactamase activity.
Key Features and Benefits
- Preloaded with 30 µg Cefsulodin: Ensures consistent and reliable results across batches.
- Spring-Loaded Cartridge Format: Easy to dispense, minimizes risk of contamination or breakage.
- Cartridge Protection: Individually sealed with desiccant, maintaining <2% moisture for extended shelf life.
- Visual Indicators: Supports detection of resistance mechanisms, antagonism, or synergy between antibiotics.
- Conforms to Standards: Compliant with DIN and SFM guidelines for AST.
- Part of Thermo Scientific’s Oxoid Range: Known for reliable, validated, and IVD-compliant microbiology tools.
