Project Details:
Tick-borne diseases are a major health concern, with Lyme disease and early summer meningoencephalitis (TBE) among the most important. Although it is known that ticks infected with Borrelia in particular are almost ubiquitous, there is no comprehensive, area-wide picture of tick infection rates and thus the human risk of infection. Using a sample set of thousands of ticks, a reliable picture of Borrelia prevalence in Germany will be obtained for the first time.
The data on tick infections obtained, together with the data on tick density from the previous project, will enable the identification of factors associated with high local Borrelia prevalence.
In addition, tick pools from selected locations, e.g. TBE endemic areas or those where human TBE cases have occurred in the respective county, will be examined for TBE virus infections.

Project Details:
The genus Pestivirus belongs to the virus family Flaviviridae and comprises RNA viruses of great relevance, like Bovine viral diarrhea virus (BVDV) and Classical swine fever virus (CSFV), which are causative pathogens of notifiable diseases. Since decades, it was commonly accepted that pestivirus infections are restricted to cloven hooved (ungulate) hosts. In the past years, several atypical pestiviruses have been discovered in non-ungulate hosts. These newly discovered pestiviruses show the typical genome organization, but are genetically highly distinct. Obviously, these novel viruses represent a new group within the pestiviruses with so far uncharacterized biological properties. In addition, such a novel pestivirus was also discovered in pigs and designated "atypical porcine pestivirus" (APPV). APPV causes a neurological disease in newborn piglets (congenital tremor) and involvement in other diseases (e.g. infertility, abortion, neonatal malformations) appears likely.
Within this research project, it was possible to adapt APPV to cell culture conditions and to propagate it. The availability of a virus isolate provided the basis for further studies to characterize the biological properties of the pathogen. Our work demonstrated that there are obviously significant differences in the cell entry of APPV and CSFV. It has been believed for long time that the complement-regulating protein CD46 is the key for pestiviruses to penetrate the host cell, but our work showed that some pestiviruses - including CSFV - use a CD46-independent mechanism for cell entry. Which cellular surface structures are used instead for cell entry is still unclear and will be the subject of further research.
The aim of the study is to provide insights into the complex, probably multi-step process of cell entry. Within this project is the aim to identify the molecular determinants of cell entry of pestiviruses and to characterize them in more detail. Several host cell factors have already been identified which apparently interact with the viral envelope proteins during early phases of viral replication and can influence virus replication. First, it has to be elucidated whether these factors directly interact with the virus particles or whether these are indirect effects, e.g. caused by binding to other cellular proteins or by an altered cell metabolism. Knowledge of the key factors for the entry of porcine pestiviruses into the host cell can make a valuable contribution to understanding the biology of the new and widespread pathogen in the pig population, APPV, as well as the properties of the long-known animal disease pathogen CSFV.

The aim of the study is to begin recording the zoonotic potential of raccoon dog, nutria and raccoon populations in Lower Saxony, taking into account the distribution of these and other susceptible animal species in the region. For this purpose, a small number of animals are sampled and autopsied from the hunting grounds. This study is funded by the hunting levy of the MELV.

Project Details:
With Alexa, Siri and Cortana, voice recognition and control software has become an integral part of our everyday lives. Animal voices also contain a huge number of information about the sender animal, such as species, identity, gender, age, body size, emotional state, diseases and hormone status. Bioacoustics therefore enables the development of non-invasive, time- and cost-efficient, automatic bioacoustic monitoring systems for animals. For this purpose, microphones can be installed recording animals' vocalisations around the clock without disturbing or influencing them. The recordings can be automatically analysed using mathematical algorithms to extract specific information. In addition, psychoacoustic tools can be used to elicit specific positive behaviours. Such bioacoustic tools can be used for clarification of taxonomic questions, to monitor wildlife as well as to improve animal husbandry and thus play an increasingly important role in species conservation and animal management. The aim of this project is to explore the wide range of possible applications and to develop bioacoustic monitoring systems for species conservation and animal management.

Project Details:
Farmed seafood is an important source of protein for food and feeds with a low-carbon footprint which has an important role to play in helping to build a sustainable food system. A strategic and long-term approach for the sustainable growth of a resilient EU aquaculture is, therefore, more relevant today than ever. However, the efficient and cost-effective control of pathogens remains among the main challenges for the sector, particularly relevant for Europe, where there is a great variety of species and production systems, which hinders the implementation of good husbandry practices tailored to each aquatic species. Through active engagement with key stakeholders, Cure4Aqua aims to jointly improve the resilience of EU aquaculture under environmental,biological, and socio-economic stress, by improving aquatic animal health and welfare and supporting the environmentally friendly, inclusive, safe, and healthy production of seafood. Cure4Aqua will do so by 1) developing cost-effective vaccines to prevent disease caused by 5 pathogens of economic significance to EU aquaculture; 2) Identifying markers with diagnostic capacity to be integrated to selective breeding programs to improve stress and disease management; 3) Developing innovative, bio-based and sustainable solutions as an alternative to antibiotics for controlling fish pathogens at various life stages and alleviate the pressure of global antimicrobial resistance; 4) Developing new tools and technology to improve health and welfare monitoring at the fish farm level and
diagnostics of fish pathogens both at the laboratory and the fish farm levels; 5) Placing fish welfare at the foreground of aquaculture production, through the development of high welfare standards that consider different life-stages, production systems, and knowledge of welfare needs, and 6) Ensuring effective external communication, dissemination and exploitation of project activities and results to all relevant target groups.

Project Details:
Parkinson’s disease (PD) is the second most common progressive neurodegenerative disorder, which is characterized by loss of nigrostriatal dopaminergic neurons and both motor and non-motor clinical features. There is no disease-modifying therapy available and the cause of the disease remains unknown. The presence of alpha-synuclein (αSyn)-positive neuronal inclusions called Lewy bodies in the substantia nigra is the pathological hallmark of PD. αSyn is a small acidic protein predominantly expressed in neurons. An unspecified pathomechanism leads to a misfolding of soluble monomeric aSyn into fibrils, which transfers "prion-like" across the brain.
We hypothesize that spread of this pathology to a given brain region is sufficient to induce the motor and non-motor symptoms observed in PD patients. Specifically, we focus on the under-treated psychiatric symptoms fear and anxiety, which may originate from pathology in the basolateral amygdala. To test our hypothesis we will stereotactically inject αSyn-preformed amyloid fibrils (PFF) in different brain regions in a mouse model with alpha-synuclein overexpression (Thy1-αSyn). Readouts are (i) spread of pathology across brain tissue and (ii) the concurrent development of progressive behavioral phenotypes.

Project Details:
MERMAID proposes to further develop tissue-based in vitro mucosa models and assays to serve as in vitro models for
infection and to study immune protection with selected immune components. As such, the models will consist of a pathogenmucosal interface with a third dimension added, i.e. the interaction with selected immune mediators mimicking a relevant
(protective) natural immune response that can or should be obtained by vaccination. The models that will be developed will
also account for the heterogeneity existing in the population. The resultant next-generation mucosal tissue models will then
be validated using specimens derived from controlled human infection model (CHIM) studies and natural infections to
confirm the relevance of the model for the in vivo situation and the selected immune mediators. Subsequently, samples from
vaccine trials will be used to assess the induction of these immune responses in vivo and prove their efficacy ex vivo in next
generation models.
