Used for Antimicrobial Susceptibility Testing (AST). The discs are placed on a bacterial culture spread across an agar plate (such as Mueller-Hinton agar). As the antibiotic diffuses into the agar, it prevents the growth of susceptible bacteria.
No specifications have been listed.
- Clear Identification: Discs are typically printed with an abbreviated code (like CTR or CRO) and the drug concentration (e.g., 30 μg) to prevent errors in the lab.
- Zone of Inhibition: The efficacy of the antibiotic is visually indicated by a clear, circular zone where bacteria have failed to grow around the disc. The diameter of this zone is measured in millimeters and compared against standardized charts to classify bacteria as susceptible, intermediate, or resistant.
- Quality Assurance: Manufactured with strict quality control strains to ensure the potency and reliability of the diffusion gradient.
