The CDC & FDA Antibiotic Resistance (AR) Isolate Bank provides curated collections of resistant organisms to help microbiologists, drug and diagnostic manufacturers, and researchers combat one of the world’s greatest infectious disease threats.

Isolates are gathered through CDC’s outbreak response and surveillance programs, validated and sequenced for testing, and then thoughtfully curated to increase lab efficiencies and public health innovations. The isolates represent samples from healthcare-associated, foodborne, gonorrhea, and community-associated infections.

Please use the following citation for any publications, protocols, or any written materials using AR Bank Isolates.
