CCUG is dedicated to archiving, characterizing and identifying microorganisms
CCUG maintains an extensive number and taxonomic range of bacteria and some yeast and fungi. The mandate of CCUG is focused on clinically-relevant bacteria. Microbial strains are accepted within the recommendations of the Convention on Biological Diversity (CBD) and the regulations of the Nagoya Protocol on Access and Benefit Sharing (ABS). Strains are lyophilized and may be exported promptly to qualified laboratories under United Nations guidelines. Strains are received from clinical, industry and environmental sources for characterisation; the CCUG typing service employs phenotyping, chemotyping, genotyping and genomic sequence determination and analyses for reliable, high-resolution classification and identification.

CCUG is in collaboration with EUCAST Development Laboratory offering a panel of S. pneumoniae with varying susceptibilities to beta-lactam for validation (more ).
Beta-lactam resistance in Streptococcus pneumoniae is best detected by screening isolates with the oxacillin 1 µg disk.
However, benzylpenicillin susceptibility can be quantitated only by MIC determination.
Some methods are well calibrated to broth microdilution (reference methodology) and others not.
In collaboration with the EUCAST Development Laboratory, a panel of 10 S. pneumoniae strains with varying susceptibilities to benzylpenicillin (and other beta-lactam agents) has been defined according to broth microdilution reference assay.
The panel is to be used for validating the performances of susceptibility testing methods.
