Thermo Scientific™ Oxoid™ Erythromycin Antimicrobial Susceptibility Discs are designed for manual disk diffusion testing using the Kirby-Bauer agar diffusion method to evaluate bacterial susceptibility to erythromycin, a macrolide antibiotic effective primarily against Gram-positive cocci and select Gram-negative organisms.
Each disc is precision-loaded and individually housed in a spring-loaded, shatterproof cartridge, sealed with a <2% moisture desiccant to maintain stability and potency. These discs meet global regulatory standards, including CLSI, EUCAST, DIN, and BSAC, and are used in routine diagnostic workflows to guide effective antimicrobial therapy.

Key Features and Benefits
- Multiple Potencies Available: Choose from 5 µg to 30 µg for diverse AST applications
- Cartridge-Based Format: Spring-loaded and color-coded cartridges ensure clean, reliable dispensing
- Desiccant-Sealed Packaging: Maintains <2% moisture content to preserve antimicrobial activity
- Validated and Compliant: Conforms with CLSI, EUCAST, DIN, BSAC guidelines for AST
- Reliable Visual Indicators: Allows for qualitative classification of resistance, contamination, and synergism
- Trusted Macrolide Profiling Tool: Ideal for detecting resistance in Staphylococcus spp., Streptococcus spp., and other erythromycin-sensitive bacteria
Intended Use
These discs are intended for use in semi-quantitative in vitro antimicrobial susceptibility testing using pure agar-grown bacterial cultures. They help determine microbial susceptibility to erythromycin, assisting clinicians in selecting appropriate treatments. For professional diagnostic use only.
Applications
- Routine AST for Gram-positive cocci, including Streptococcus pneumoniae, Staphylococcus aureus, Enterococcus spp.
- Erythromycin resistance profiling in respiratory, skin, and soft tissue infections
- D-test confirmation in inducible clindamycin resistance testing
- Public health AMR surveillance
- Diagnostic microbiology workflows in hospital labs
- Teaching and training in AST procedures
Thermo Scientific™ Oxoid™ Erythromycin Antimicrobial Susceptibility Discs offer accuracy, regulatory compliance, and versatility in manual AST workflows. Available in four disc strengths, they are an essential component of AST panels for macrolide resistance detection in clinical and public health laboratories.
