Fungal & Bacterial Identification

Fungal & Bacterial Identification

Our accredited 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 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.

As well as our accredited service, we offer bespoke molecular services such as fingerprinting, identification of nematodes, barcoding etc. Morphological identifications are also available on request for fungi and we also offer a MALDI-ToF service for bacteria. Other methods are available such as Next Generation Sequencing. 

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 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 2019-2020.

Normal service:

From receipt of a pure sample, expected turnaround times are up to 14 days for bacteria and 14-21 days for moulds (filamentous fungi) and yeasts.

Priority service:

The expected turnaround times from receipt of a pure sample are 7 days for bacteria and 7-10 days for fungi and yeasts. Please contact us in advance for this service via

Top priority service:

Processing of your sample will be fast-tracked. Expected turnaround times are 2-5 working days depending on the nature of the sample. Please contact us in advance for this service via

Please note: Timescales given are based on receipt of pure samples in suitable condition for processing. Pure samples are preferable and will lead to a faster service, but we can isolate if required for an extra charge.

We provide a comprehensive identification report with the following options:

Name of organism only: 

Provides the scientific name of each organism, process used and level of identity to sequences of validated type strains or reference strains.

Detailed sample report:

Provides in addition:

Details of the occurrence, habitat and geographical distribution of the organism
An indication of the pathogenicity, toxicity and hazard status of the organism
Literature references

Sequence data:

Provides the molecular sequence and list of top matches.

If you belong to one of our Member countries 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 before sending your samples to us.
