Standardization of diagnostic protocols (Diagpro) for Erwinia amylovora in the European Union.
Different reagents and methods have been reviewed, selected, improved, standardized and validated for the detection and diagnosis of E. amylovora. The validated methods and protocols will be published on an Internet web-site for comments and will be included as the European Union official scheme for the detection and identification of the bacterium. A combination of two different methods based on serology and PCR in addition to isolation, followed by a pathogenicity test, will be required to officially confirm the E. amylovora presence. The detection of the bacterium in symptomless plant material must be assayed after a validated enrichment step.
