CAUTION
This article is worded and codified by unit to make the order easier, but is always packaged in kit of 250 discs
Definition
A susceptibility testing disc impregnated with a defined amount of a specific antibacterial is intended to be used to determine the susceptibility of a specific bacterial organism (excluding mycobacteria) isolated from a clinical specimen by culture, using an agar diffusion method.
Specifications
- CEFTRIAXONE, 30 μg
- Code: CRO
- clsi
- eucast
- Compatibility with disc dispensor
- 1st choice
Quality Standards Comment
This method is based on a standardized procedure published by the WHO and adopted as consensual standard by the CLSI (Clinical and Laboratory Standard Institute), CA-SFM (Comité de l'Antibiogramme, Société Française de Microbiologie), and EUCAST (European Committee on Antimicrobial Susceptibility Testing).
Technical specifications
- 6 mm filter paper discs
- Absorbent paper impregnated with precise concentrations of antimicrobial agents
- The discs are clearly identified by a code: 1 to 3 letters for the antimicrobial agent and 1 to 3 figures for the concentration of the antimicrobial agent, printed on each side of the disc
- Discs dispenser needs ideally to be from the same brand as the discs to fit the cartridges
Packaging & Labelling
- 5 x 50 discs.
- Cartridges are individually packed in a foil-sealed blister pack with a desiccant
Transport Dangerous Goods
Transport not regulated
To be Ordered Separately
- Discs dispenser: must be from the same brand as the discs. Only discs from Oxoid are compatible with the disc dispensor (Oxoid). Discs from other brands need to be placed manually on the plate using a forceps.
- Culture media
- Bacterial strains for quality control
- Densitometer
Instructions for use
- Follow the instructions in the leaflet.
- Follow the instruction of the current guidelines (CLSI, CA-SFM, EUCAST).
- Susceptibility testing quality controls should be done with the quality control strains detailed in the SBQC chapter, with the frequency described in the SOP.

Precautions for Use
All biological samples must be considered as potentially infectious and handled with the usual precautions (compulsory wearing of gloves, hand washing, etc.).
Storage
- Shelf life : 36 months
- Guaranteed minimum remaining shelf life at delivery: 1/3 of the total shelf life.
- Not to be used beyond the expiry date
- Unopened cartridges must be stored at -20°C to 8°C. Unopened cartridges should be allowed to come to room temperature before removing them from the packaging to minimize condensation as this may reduce the potency of the antimicrobial agent.
- Once the cartridges are open they need to be stored within the dispenser in the container provided with a charged desiccant, or other suitable opaque air tight container with a charged desiccant to protect the discs from moisture.
- Dispensers should be stored within the container in the refrigerator.
- Once a cartridge is open, it is recommended that it is stored for no more than 7 days.
Waste management
After use, sterilise the cultures and all contaminated material. Please contact your watsan referent for advice on proper disposal.
