EPPO activities on diagnostics

Since 1998, EPPO has established a work programme in the area of diagnostics to harmonize procedures across the EPPO region. This programme mainly focuses on the diagnostics of pests which are regulated as quarantine pests. The different activities conducted in this framework are described below.

EPPO diagnostic Standards

More than 140 EPPO diagnostic Standards have been published

Since 1998, more than 140 EPPO diagnostic Standards have been prepared by EPPO. All have been published in the EPPO Bulletin and are also stored in the EPPO Global Database. This set of Standards includes horizontal and pest-specific Standards.

- Horizontal Standards include Standards related to quality assurance issues, Standards on how to perform specific methods, such as ELISA test for viruses, DNA barcoding as an identification tool for a number of regulated pests etc.

- Pest-specific diagnostic Standards (Diagnostic protocols) are related to specific pests (a single species or groups of species) and provide the guidance necessary for an expert or competent staff who are specifically trained to detect and positively identify these pests by a single test or combination of tests.

How EPPO diagnostic Standards are prepared?

Preparation

The preparation of Standards involves close collaboration between different EPPO Panels involved in diagnostics. These Panels are composed of diagnostic experts nominated by the NPPOs of the EPPO member countries. The EPPO Panels involved in diagnostics are the following (click on the links to view their composition):

Drafts of pest specific Diagnostic Standards (Diagnostic protocols) are initially prepared by an individual expert or a group of experts (drafting team) according to a common format which ensures that the draft contains all necessary information to detect and positively identify a particular pest (instructions for authors ). Whenever available, validation data is also provided for the different tests included in the diagnostic protocols. The draft protocols are reviewed by the relevant Panels and submitted to a consultation phase among all EPPO member countries to ensure their wide acceptance.

For horizontal Standards no specific format exist but as pest Specific ones, draft are usually prepared by an individual expert or a drafting group.

Approval

As it is the case for all EPPO Standards, diagnostic Standards are officially approved and then published in the EPPO Bulletin.

Evaluation of the need for revision

For each pest-specific diagnostic protocol one (or more) expert from the relevant Panel is responsible for reviewing the new literature for this pest before each Panel meeting and informing the EPPO Secretariat if there is a need to revise the protocol (e.g. due to new improved tests being developed which should be included or changes in taxonomy).

EPPO pictorial glossary of morphological terms in nematology

Since 2013, the EPPO Panel on Diagnostic in Nematology has been developing a pictorial glossary of morphological terms in nematology. This document lists all nematological terms used in the EPPO diagnostic protocols on plant parasitic nematodes with their definitions.

EPPO databases on diagnostics

EPPO database on diagnostic expertise

In 2004, EPPO Council stressed that the implementation of phytosanitary regulations for quarantine pests was jeopardized by decreasing knowledge in plant protection and made an official declaration (Plant Health Endangered, also known as the ‘Madeira declaration’). The Panel on Diagnostics proposed that an inventory should be made of the available expertise on diagnostics in Europe. A database on Diagnostic Expertise was then created to allow identification of experts who could provide diagnosis of regulated species or help in the identification of new or difficult species. Experts from more than 100 diagnostic laboratories of the EPPO region have provided details about the pests they can diagnose and the methods they use. EPPO member countries are encouraged to continue to provide data on their laboratories and expertise.

In May 2020, EPPO launched a renewed version of the database. The new version was prepared in the framework of an EU funded project VALITEST and the outcome of the redesign is a more searchable and user-friendly database.

EPPO-Q-bank

EPPO-Q-bank is a database to support diagnostic activities on plant pests which was transferred to EPPO and officially launched in May 2019. The primary aim of EPPO-Q-bank is to host sequence data for a number of pests, as well as to provide information on biological material, in particular from where this material can be obtained. Information is provided per discipline (arthropods, bacteria, fungi, nematodes, phytoplasmas, viruses & viroids, and invasive plants).

Workshops and Conferences on Diagnostics

Since 1985, EPPO has organized a series of workshops and conferences on diagnostics.

Conferences on diagnostics (1985, 1994, 2000 and 2012 in NL - 2009 in GB - 2015 in FR)
Workshops on Quality Assurance (2007 in DK - 2009 and 2014 in GB)
Workshop for Heads of laboratories (2011 in AT - 2013 in TN - 2015 in IT)
Workshop on 'cut-off data' for real-time PCR (2013 in FR)

Partnerships and special projects

EPPO and IPPC Diagnostic protocols

EPPO Panels are reviewing Diagnostic protocols prepared at IPPC level to prepare regional positions to be used by EPPO Countries during the IPPC consultations.

Ms Petter (EPO Assistant Director) is also invited to attend the IPPC Technical Panel on Diagnostic Protocols (and several meetings of that Panel have been hosted in the EPPO Headquarters).

Euphresco

Since 2014, EPPO is hosting Euphresco, a network of organizations (e.g. NPPOs, research institutes) funding and coordinating research in plant health. Many projects funded by the Euphresco network relate to diagnostic issues.

Euphresco website

European Commission

EPPO has a close collaboration with the European Commission (EC) and an expert from the EC attends all EPPO Diagnostic Panels.

European Union reference laboratories

EPPO has a close collaboration with the 5 European Union Reference Laboratories (EURLs) with the objective to work in synergies and avoid the duplication of the work. An expert from each EURLs attends the relevant EPPO Diagnostic Panels and the EPPO Secretariat is invited to the workshops organised by the EURLs. Some EURLs experts are also involved in other EPPO activities (e.g. in the curation of EPPO-Q-bank).

European Co-operation for Accreditation (EA)

The European Co-operation for Accreditation (EA) is the European network of nationally recognised accreditation bodies located in the European geographical area. In 2009, a joint communiqué was signed by EPPO and EA stating that 'EA will recommend that assessors from Accreditation Bodies take note of EPPO documents when evaluating plant pest diagnostic laboratories'. Since 2011-01 EPPO is a 'recognized stakeholder' for EA. A revised version of this communiqué was signed in October 2018.

European Association of Phytobacteriologists

EPPO collaborates with the European Association of Phytobacteriologists (EAP) and the Panel on Diagnostics in Bacteriology and the EAP regularly have back to back meetings.

European Mycological Network

EPPO collaborates with the European Mycological Network (EMN) and the Panel on Diagnostics in Mycology and the EMN regularly have back to back meetings.

Special projects

In addition to its regular programme of activities, EPPO participates in various projects that are conducted over a fixed period of time and that may be funded by the Organization itself, part of its members, or other organizations. In the field of diagnostics, EPPO has participated in several projects, such as Q-detect, Q-collect and TESTA. EPPO is currently a partner in the EMPHASIS, XF-ACTORS and VALITEST projects.
