Deposit your bacteria

Why deposit with us?

There are two main reasons why scientists and clinicians deposit bacteria strains with the National Collection of Type Cultures (NCTC).  Firstly, when they isolate a novel species of bacteria, as part of the process of naming and describing the organism, authors are required to deposit the type strain in at least two culture collections located in different countries to comply with the Bacteriological Code.  They must also provide documentary evidence that the strains have been deposited, are viable and available to other researchers without restrictions on their use for taxonomic research.     

Secondly, many researchers ensure the bacterial strains they isolate (for example as part of an outbreak investigation and/or for their particular characteristics) are preserved and available to the wider scientific community.

How to deposit bacteria

The process for depositing strains is relatively simple and requires a dialogue between the depositor and NCTC. We will ensure that relevant biosafety and culture information is captured. The system is deliberately flexible to allow for any depositor restrictions or requirements.

If you have difficulty obtaining dry ice or shipping infectious material please contact us for assistance.

Please note: when depositing a proposed novel species of bacteria all information associated with the strain will be held as confidential, and the strain will not be made available by NCTC for three years or until the depositor receives a response to their literature submission. The three years can be prolonged if, in any circumstance, the depositor requires an extension in the future. However, in this case, we rely on depositors keeping us informed on the progress of their publication

Please wait for notification of acceptance of your strain(s) before shipping.
