Description
Key Features
Product Type: Antimicrobial Susceptibility Testing (AST) Disc.
Antimicrobial Agent: Cefazolin (a first-generation cephalosporin antibiotic).
Disc Potency: 30 µg (micrograms) of Cefazolin per disc.
Brand: BBL™ Sensi-Disc™.
Format: Supplied in a cartridge of 50 discs, designed for use with an appropriate disc dispenser.
Function: The disc contains a precise, standardized amount of the antibiotic for diffusion testing.
Uses
The primary use of the Cefazolin Sensi-Disc is in clinical and industrial microbiology laboratories for Antimicrobial Susceptibility Testing.
Antimicrobial Susceptibility Testing (AST): Used to determine the in vitro sensitivity or resistance of a bacterial isolate (often Gram-positive organisms like Staphylococcus) to the antibiotic Cefazolin.
Procedure:
The disc is applied to an agar plate (typically Mueller-Hinton) inoculated with a bacterial isolate.
After incubation, the diameter of the zone of inhibition (clear area where bacteria did not grow) is measured.
This measurement is compared to standardized criteria (e.g., CLSI) to classify the bacteria as Susceptible, Intermediate, or Resistant to Cefazolin.
Clinical Relevance: The results guide clinicians in selecting appropriate antibiotic therapy for infections where Cefazolin is a potential treatment option (e.g., skin infections, surgical prophylaxis).
