Our molecular methods use sequencing of the 16S region of rDNA for bacteria and sequencing of the ITS region of rDNA for filamentous fungi and yeasts. Results from each sample are matched, by our specialists, against global databases of sequenced organisms to establish their identity. For fungi and yeasts, alternative loci and morphological methods are also used where necessary to provide a fully rounded approach to finding the closest species match.
We also offer bespoke molecular services such as fingerprinting, identification of nematodes, barcoding of insects, etc. Morphological identifications are also available on request for fungi and we also offer a MALDI-ToF service for bacteria as well Next Generation Sequencing options. We are happy to tailor our services to your needs so please contact us to discuss your requirements. With our experts and contacts, if we can’t provide what you need, then we usually know someone who can.
Please note: CABI does not accept samples that are considered hazardous or any materials clearly labelled as such. If you believe your sample may present a hazard, please contact CABI to discuss the sample in more detail.
Any costs incurred through incorrect packaging and labelling or sending of restricted/hazardous samples without prior consent will be the responsibility of the sender.
It is highly recommended that any individual sending samples for testing undertakes a shipping and handling course in order to ensure that samples are correctly packaged and labelled appropriately and in accordance with the law.
CABI does not handle microorganisms in Category A. Category A organisms are classified as infectious substances which are capable of causing permanent disability, life-threatening or fatal disease in otherwise healthy humans or animals. These include all microorganisms in hazard group 3. For further information about Category A organisms, please see the WHO Guidance on regulations for the Transport of Infectious Substances. In order to achieve the fastest identification processing times, we recommend the provision of pure cultures or we can offer an optional isolation service.
Please contact microbialservices@cabi.org for an Identification Request Form.
CABI Member Country identification
If you are a CABI Member Country and your samples are causing disease to agricultural crops, you may be eligible for our free service. This service is limited and we cannot accept potential human pathogens so for details, contact us at microbialservices@cabi.org before sending your samples to us.
