Thermo Scientific™ Oxoid™ Ertapenem ETP Antimicrobial Susceptibility discs, 10 μg

The Thermo Scientific™ Oxoid™ Ertapenem Antimicrobial Susceptibility Discs (10 µg) are precision-manufactured paper discs used for semi-quantitative determination of microbial susceptibility to ertapenem, a broad-spectrum carbapenem-class β-lactam antibiotic. Designed for manual antimicrobial susceptibility testing (AST) using the Kirby-Bauer disk diffusion method, these discs support the accurate identification of resistant, intermediate, and susceptible bacterial strains—critical for guiding appropriate clinical treatment decisions and resistance surveillance.

Each disc is housed in a shatterproof, spring-loaded cartridge that is individually sealed with a desiccant to maintain moisture levels below 2%, ensuring long-term stability and performance. The clear cartridge labeling and end-of-cartridge indicators simplify handling and enhance workflow efficiency in microbiology laboratories.

Key Features and Benefits

• Potent 10 µg Ertapenem Formulation
  Enables accurate detection of carbapenem susceptibility in Enterobacteriaceae, Klebsiella spp., Escherichia coli, and other clinically significant Gram-negative bacteria.
• High-Quality Cartridge Design
  Spring-loaded and shatterproof cartridges provide ease of use and contamination prevention.
• Enhanced Interpretation Capability
  Disc diffusion method offers both categorical results and visual cues such as:
  • Inoculum density
  • Mixed cultures or contamination
  • Resistant mutants
  • Synergistic or antagonistic antibiotic interactions
  • β-lactamase activity
• Validated to International Standards
  Complies with CLSI, EUCAST, and BSAC guidelines for reliable global use.
• Long-Term Stability
  Each disc cartridge is sealed with desiccant for extended shelf-life and consistent potency.

Applications

• Clinical microbiology laboratories
  Detection of resistance to carbapenems in Gram-negative rods, especially CRE surveillance.
• Hospital antimicrobial stewardship programs
  Phenotypic detection of resistance mechanisms for infection control.
• Pharmaceutical microbiology and R&D
  For antimicrobial screening and efficacy validation in drug development pipelines.
• Public health and reference laboratories
  Monitoring resistance trends and validating phenotypic testing protocols.

Specifications

Intended Use Statement

Thermo Scientific™ Oxoid™ Ertapenem Discs are intended for in vitro diagnostic use in the semi-quantitative disk diffusion (agar diffusion) method. These discs help clinicians evaluate the susceptibility of bacterial pathogens to ertapenem in pure cultures grown on agar. They are not intended for use with automated AST platforms and are not companion diagnostics. Professional use only.

Thermo Scientific™ Oxoid™ Ertapenem 10 µg Discs provide a robust, reproducible, and standards-compliant solution for detecting carbapenem susceptibility in clinically important pathogens. With user-friendly cartridge technology and reliable performance, they are an essential tool in AST workflows focused on combating antimicrobial resistance (AMR).
