RESISTANCE QUALITY CONTROL MICROORGANISM
Definition
Phenotypically characterized resistant strains that are developped according to the recommendation of/made available by the European Society of Clinical Microbiology and Infectious Diseases (EUCAST) for quality control.
The microbial strains have specific resistance mechanisms (ESBL, MRSA, ...) and phenotypically reproducible levels of susceptibility.
They are lyophilized into pellets.
The microbial strain preparations are derived from ATCC® (American Type Culture Collection), NCTC® (National Collection of Type Cultures, operated by the UK Health Security Agency (UKHSA)

Quality Standards Comment
EUCAST recommendations - version 8
Components
The quality control microorganisms are packaged in a resealable vial that contains five lyophilized pellets of a single microorganism strain and a desiccant to prevent adverse accumulation of moisture
Technical specifications
- Freeze dried bacterial strains
- ATCC: Each lyophilized microorganism preparation is less than or equal to four (4) passages from a reference culture.
- NCTC: Each lyophilized microorganism preparation is one (1) passage from the reference NCTC culture.
- Microorganisms for standard protocols should be used within five passages of the ATCC reference culture.
Packaging & Labelling
1 vial contains 5 lyophilized pellets
Transport Dangerous Goods
