Clinical Isolates Collection

An intelligent solution to a global problem

The ATCC® Clinical Isolates Collection comprises a targeted set of antimicrobial-resistant clinical isolates that support drug discovery and assay development. Each strain in the collection has validated genotypic and phenotypic activity against a variety of critical drug classes, and is provided with: 

  • Susceptibility data – MIC values and susceptibility profiles provided*
  • Genetic data – NGS-assembled whole genome sequence with predicted annotated antibiotic resistance and rRNA genes provided in multiple file formats (.pdf, .txt, .xls, .zip) 
  • Source information – Data such as geography, collection date, and collection site

What’s more, we have taken all of the guesswork out of strain selection! With our new selection tool, you can quickly search for the strains you need by gene activity or drug resistance, enabling you to get your research started faster.

*The minimum inhibitory concentration (MIC) ranges for resistant, intermediate, and susceptible are based on criteria within the Clinical and Laboratory Standards Institute (CLSI) Performance Standards for Antimicrobial Susceptibility Testing, 26th Edition. Please note that several drug types, including Ceftazidime-avibactam, Ceftrixone, Colistin, Colistin-P80, and Tigecycline, may not currently have CLSI-recommended MIC ranges available for all of the strains tested, and thus cannot be classified as resistant, intermediate, or susceptible. However, the MIC values for these drug types will be provided upon purchase. Breakpoints on some of these compounds have been set by regulatory bodies in individual geographies or countries, and breakpoints are also provided for some organisms by manufacturers.
