Thermo Scientific™ Oxoid™ Gentamicin CN Antimicrobial Susceptibility Discs

Thermo Scientific™ Oxoid™ Gentamicin Antimicrobial Susceptibility Discs are high-quality, ready-to-use discs designed for manual Antimicrobial Susceptibility Testing (AST) using the Kirby-Bauer agar diffusion method. These discs contain calibrated concentrations of gentamicin, an aminoglycoside antibiotic used to treat a wide range of Gram-negative and selected Gram-positive bacterial infections.

Each disc is housed in a spring-loaded, shatterproof cartridge, individually sealed and desiccant-protected (<2% moisture) to ensure maximum stability, potency, and performance. These discs are compliant with CLSI, EUCAST, DIN, and BSAC guidelines, supporting global standards for accurate phenotypic resistance testing.

Intended Use

These discs are designed for semi-quantitative agar diffusion susceptibility testing of pure agar-grown cultures. Used in clinical diagnostic workflows, they support therapy decisions by determining in vitro susceptibility to gentamicin. For professional use only.

Applications

• Routine AST of Gram-negative bacilli (e.g., E. coli, Pseudomonas spp., Klebsiella spp.)
• Resistance detection in Gram-positive cocci, including Enterococcus spp.
• High-level aminoglycoside resistance (HLAR) screening with CN120–CN500
• Hospital AST panels and infection control programs
• Teaching and training in academic microbiology labs
• AMR surveillance in public health and veterinary settings

Thermo Scientific™ Oxoid™ Gentamicin Antimicrobial Susceptibility Discs provide a robust and reliable solution for detecting resistance to gentamicin across a range of clinical pathogens. With six potency options, cartridge-pack efficiency, and international regulatory compliance, these discs support standardized AST workflows in clinical, veterinary, academic, and public health laboratories.
