This real-time RT-PCR is a molecular tool for detection of Foot-and-mouth disease virus lineage O/ME-SA/SA-2018, as it is an emerging lineage in South Asia since 2018. The assay has been tested on 34 FMDV positive samples (including 12 SA-2018 samples) with a specificity of 91,7% (11/12 SA-2018 samples detected). The primers and probes are indicated hereafter:

NB: This system has been validated on a small number of samples and should therefore be tested against other samples from this lineage.
An outbreak of Foot-and-Mouth Disease has been reported in Germany in water buffaloes. The outbreak is located in the Brandenburg region, close to Berlin (first reports of this disease in Germany since 1988). This is the first case in the EU since 2011 in Bulgaria. According to the regional authorities, three water buffaloes are confirmed as infected. Restriction zones have been set up around the outbreak. The identification of the serotype is pending.

We’re glad to inform you that the report of the inter-laboratory test evaluating the performance characteristics of the pan-lyssavirus real-time RT-PCR tests has just been released.
We would like to warmly thank all the participants for their implication and their contribution in a better understanding of the available pan RT-PCR techniques, their variations and implications.
The report is available under restricted access here (onglet ILT reports).
The Centre is celebrating the publication of its eighth scientific article as a result of the work carried out in Activity 3 in 2023-2024.
The aim of this study was to assess the performance of latency-to-lie tests without the addition of water, making them more practical for use on farm.
This article named "Research Note: Testing the validity of latency-to-lie tests without water for objective on-farm assessment of walking ability of broiler chickens" has been published in Poultry Science and is available here.
EURCAW Aquatic Animals has their website up and running.
Like the other EURCAWs, Aqua will be posting all of their publications, news and training on their website.

On November,13th 2024, Anja B. Riber participated in the NordCAW Poultry Welfare Conference 2024, at the Swedish University of Agricultural Sciences (SLU) in Uppsala, Sweden.
Her oral communication was entitled "What’s on the European poultry welfare agenda". The talk addressed specific poultry welfare topics that are currently of interest to many EU stakeholders, including growth rate of broilers, on-farm hatching; male layer chicks, keel bone fracture, end-of-cage age, mutilation, enrichment and assessment of positive welfare.
The conclusions were that:
1) topics important to the welfare of poultry in the EU are discussed,
2) there are, not surprisingly, some gaps of knowledge,
3) solutions for improving poultry welfare often exist, but progress still seems slow likely because of the clash with other interests, such as economy and the climate change agenda.
The presentation was part of the subactivity 1.1 Network building.
