Isolate Bank Requests

Consult the Isolates Currently Available webpage before filling out this form.

An extensive collection of isolates for some bacterial pathogens are available through the Active Bacterial Core surveillance (ABCs) Isolate Bank.

Available pathogens include:

  • Group A Streptococcus
  • Group B Streptococcus
  • Haemophilus influenzae
  • Neisseria meningitidis
  • Streptococcus pneumoniae

CDC isolate bank custodians review requests for isolates prior to approval and release. CDC strictly enforces a limited distribution policy that prohibits the secondary distribution of ABCs isolates to third-party researchers.

Please contact us for the current price per isolate, which applies to for-profit institutions only. All requestors are required to pay shipping fees. The CDC Biorepository (CBR) stores and ships the isolates.

To request isolates, please fill out the following information and provide a 1 to 2 page summary document as described below.
