Thermo Scientific™ Oxoid™ Tetracycline Antimicrobial Susceptibility discs, 30µg

Thermo Scientific™ Oxoid™ Tetracycline Antimicrobial Susceptibility Discs are designed for reliable, manual antibiotic susceptibility testing (AST) using the disk diffusion method. These discs are available in two concentrations—10 µg and 30 µg—to meet standard clinical and veterinary microbiology testing requirements. Conforming to CLSI, EUCAST, and BSAC guidelines, they are used for assessing bacterial susceptibility to tetracycline, a broad-spectrum antibiotic effective against both Gram-positive and Gram-negative organisms.

Each disc is precisely loaded with the stated amount of tetracycline and packaged in individually sealed, spring-loaded cartridges with built-in desiccants. This maintains disc potency and moisture levels below 2%, ensuring accurate and reproducible inhibition zone readings even with long-term storage.

Key Features & Benefits

• Two Available Concentrations: 10 µg and 30 µg discs support flexible susceptibility profiling in clinical and veterinary applications.
• CLSI/EUCAST Compliant: Meets international standards for quality and performance.
• Shatterproof Cartridges: Easy-to-load spring-loaded design prevents breakage during handling.
• Desiccant-Sealed Packaging: Maintains disc stability and potency by controlling humidity.
• Visual Diagnostic Support: In addition to zone diameter measurement, diffusion patterns may reveal contamination, inoculum density, resistant mutants, or beta-lactamase activity.
• Reliable Zone Interpretation: Suitable for semi-quantitative testing of tetracycline susceptibility for multiple bacterial strains.

Applications

• Phenotypic determination of bacterial resistance or susceptibility to tetracycline.
• Diagnostic microbiology for treatment guidance in human and veterinary infections.
• Use in quality control and surveillance studies of antimicrobial resistance (AMR).
• Suitable for Gram-positive and Gram-negative organisms such as E. coli, Staphylococcus aureus, Enterococcus spp., and Salmonella spp.
