DNA sequencing can be performed to identify bacterial isolates to a species or pathovar level. Testing can be performed on fresh isolates sent in to our labs or as an additional service to identify bacteria isolated from a sample sent in for testing. DNA is extracted from the bacterial isolates and prepared for sequencing which is carried out off site by Eurofins Genomics. Sequence analysis is carried out by comparison with publicly available sequence data as well as in-house generated phylogenetic data from known reference strains obtained from the National Collection of Plant Pathogenic Bacteria (NCPPB) and other official collections.

When sending plant pathogens and invertebrate samples from outside England and Wales for testing please email the Crop health team (crophealth@fera.co.uk) who will issue you with the relevant Letter of Authority to ensure your samples are not delayed upon entry to the UK.
