What is the ABCs Isolate Bank?

The Active Bacterial Core surveillance (ABCs) Isolate Bank is an extensive collection of isolates for some ABCs pathogens. Learn more about ABCs.

ABCs sites send bacterial isolates from a normally sterile site (e.g., blood, cerebrospinal fluid) to CDC and partner reference laboratories for antibiotic susceptibility testing and serotyping. Identifying data are limited to ensure that all information associated with the isolates is anonymous.

On this website, you will find information about the available isolates, as well as the proper procedure for requesting them.

The ABCs Isolate Bank is a joint project of CDC’s Division of Bacterial Diseases, the National Center for Immunization and Respiratory Diseases, and the CDC Biorepository – or CBR.
