Central Veterinary Institute, part of Wageningen University and Research Centres – Lelystad

Dutch National Reference Laboratory

The Central Veterinary Institute (CVI) collaborates with public and private partners to safeguard animal and public health. CVI contributes to the prevention, eradication and control of animal infectious diseases through research, diagnostics and consultancy. By doing so, CVI helps to guarantee international trade and to preserve the international top position of the Dutch livestock industry. In 1904 we started as the National Serum Institute in Rotterdam. In 1959 this institute merged with the Governmental veterinary research institute (situated in Amsterdam) into the CVI. CVI is the national reference institute for notifiable animal diseases in the Netherlands. For these diseases CVI has an important and decisive task to determine the final diagnosis.

Rabies in the Netherlands

In the period from 1875 to 1923 several laws were installed to eradicate dog as well as sylvatic rabies in the Netherlands, leading to the official OIE rabies free status in 1923. In the period from 1974-1988 the free status was lost however, due to a reintroduction of sylvatic rabies through foxes from the east through Belgium and Germany. After 1988 the country regained it OIE free status but by then was confronted with a new phenomenon, European bat lyssavirus. Since 1987 a nationwide surveillance system was set up, and since then, over 5000 bats have been tested for EBLV, resulting in 377 cases of EBLV-1 in serotine bats and 5 cases of EBLV-2 in pond bats. Since that time the only classical rabies cases were import cases.
The last incident occurred in 2012 when a 8,5-week-old puppy was imported from Morocco. A day after arrival in Amsterdam the puppy showed aggressive behaviour and two days later suspicion of rabies arose and was confirmed by CVI. Over forty people were given post-exposure-prophylaxis and several contact animals were euthanized for rabies testing.

Laboratory and staff

Rabies diagnostics at CVI is performed by the Diagnostic Unit. All suspect cases, bats as well as larger mammals (mostly foxes and dogs) are tested by FAT and real-time RT-PCR. The FAT is ISO17025 accredited, as well as the EBLV-1 real-time PCR. Other PCR tests such as the RABV and EBLV-2 real-time PCR and several conventional PCR are extensively validated and run under ISO9001 standards. The Fluorescence Antibody neutralisation test (FAVN) is used for determination of antibody titres in pets as well as humans. These tests are performed by a team of technicians and staff to authorize results.
Since CVI has a 24/7 duty to perform rabies diagnostics in cases of direct contact of humans with suspect animals such as bats or sometimes foxes we maintain a minimum of eight people per team. Besides the diagnostics tasks, CVI has limited resources for rabies research. Besides phylogenetic analyses of all the positive bat cases and a study on molecular species determination we have been involved in several studies aiming at further analysis of bats in search of other potential zoonotic viruses. In 2012 we co-authored a paper on bat Coronaviruses in the Netherlands and to date we are involved in a study on the Dutch ABC islands (Aruba, Bonaire and Curacao).

The annual online activity questionnaire was submitted to all National Reference Laboratories (NRLs) early 2016 to collect and collate data on methods used and results of tests carried out in the Community in the frame of rabies control programmes (Commission regulations (EU) N° 737/2008 and N°415/2013). This document reviews the 2015 analysis performed in 27 NRLs from the European Union and in 7 NRLs from third countries involved in a rabies control programme. The report is available n the private part of the EURL for rabies website for private members only.

The inter-laboratory test for rabies diagnosis is now over. A total of 54 laboratories, including 28 non-EUMS laboratories participated to the 2016 session of the test. This year the test was composed of a panel of 10 samples to be tested with the chosen technique(s) (FAT, RTCIT, Conventional and/or Real Time RT-PCR) and a corresponding online technical questionnaire for each tested technique. The report should be available in autumn 2016. In the meantime, participants will receive an online satisfaction questionnaire regarding this test.
 

♦ 16 June 2016 ♦

Despite the unfortunate Alsatian weather of the day, the annual Workshop for Rabies was a frank success. Forty-five rabies European scientists attended the meeting in the European Capital City of Strasbourg, leading to constructive exchanges on rabies. Additionally to the representative of the European Commission, Pedro Rosado Martin (G5 Unit of EC DG Santé), the EURL team was pleased to welcome for the first time speakers from the Food and Agriculture Organization of the United Nations (FAO) and from the French Directorate General for Food (DGAl).

The analysis of the results of inter-laboratory tests for rabies diagnosis organized in 2015 by the EURL for rabies was, as usual, presented with an open discussion on the subject. The EURL for rabies also presented on one hand a performance study of disinfectants used in the context of molecular biology techniques, and on the other hand the progress of the study on the evaluation methods of Real Time RT-PCR.

The Balkan region was in the spotlight this year, and several laboratories attended the meeting (Albania, Bosnia and Herzegovina, Republic of Kosovo, Former Yugoslav Republic of Macedonia and Serbia) as well as other eastward countries such as Moldova, Ukraine and Turkey. Each of them presented both the rabies situation and the rabies programmes in progress in their country.

Presentations are available on the EURL for rabies website for private members only.

Next workshop for rabies will be organized in June 2017 in Spain, together with the meeting of the EURL for rabies serology.

“The first issue of Euroreference (Journal of Reference) was launched in June 2009 as a free online AFSSA publication in both French and English. The original aim was to facilitate the dissemination of information about refe¬rence activities among stakeholders both at national and European levels. The topics covered included all scientific and technical aspects of analytical methods and their role in surveillance plans and reference-related regulatory issues. As a common forum for members of reference laboratory networks and all the players concerned, it was geared to National and European Reference Laboratories, animal health and food safety diagnostic laboratories, Ministries and decision-makers, directors of institutions, etc. The AFSSA/ ANSES Editorial board was rapidly joined by representatives of CODA-CER¬VA (Belgium), ISS (Italy) then PIWET (Poland).” The new of EuroReference is “co-edited by CODA-CERVA (Belgium), ANSES and SCL (France), BfR and FLI (Germany), ISS, IZSAM and IZSLER (Italy), PIWET (Poland), APHA and FERA (UK) in addition to the EPPO.” A .pdf version of EuroReference can be downloaded on the website.
