Project Details:
Schwere COVID-19-Krankheitsfälle sind durch das Auftreten einer schweren Lungenentzündung charakterisiert, die häufig einen Krankenhausaufenthalt erfordern. Bis zu einem Drittel der hospitalisierten Patienten entwickeln kritische Komplikationen, wie einen diffusen Alveolarschaden, welcher zum akuten Atemnotsyndroms (ARDS) führt. Ein detailliertes Verständnis der komplexen Pathogenese und der daraus resultierenden Krankheitskomplikationen ist dringend erforderlich, um wirksame Behandlungsstrategien für die SARS-CoV-2-Infektion zu entwickeln. Mehrere erfolgreiche Präventionsstrategien wie Impfstoffe wurden entwickelt und für ihre Anwendung beim Menschen zugelassen. Wir sind jedoch noch weit von einer Eindämmung der Krankheit entfernt und könnten mit dem vermehrten Auftreten von Virusvarianten vor zusätzlichen Herausforderungen stehen. Zwar ist bereits viel über die Pathogenese und Behandlung der akuten COVID-19 Erkrankung bekannt, jedoch wissen wir immer noch sehr wenig über die potentiellen Langzeitfolgen. Es wird immer deutlicher, dass eine protrahierte Genesung ein häufiges Merkmal COVID-19 ist, ein Phänomen, das allgemein als "Long-COVID" oder Post-COVID-Syndrom bezeichnet wird. 30-60% der Personen leiden nach der Genesung von einer akuten Virusinfektion an anhaltenden Symptomen wie Müdigkeit, Kurzatmigkeit und verringerter Belastbarkeit. Dieses Projekt soll dazu beitragen, die Mechanismen von "Long-COVID" besser zu verstehen und daraus neue Behandlungsstrategien abzuleiten.

Die Zusammensetzung und Reaktivität des lungenspezifischen Immunsystems wird durch verschiedene Mechanismen gesteuert. Wichtig ist hierbei insbesondere die körpereigene, genetische Disposition des Individuums. Genetische Varianten sind wichtige Determinanten der kindlichen Asthma- und Virusinfektionsanfälligkeit . Aber auch äußere Faktoren wie Infektionen, Rauchen oder Umweltgifte können das Immunsystem des Lungengewebes prägen. Neuste Studien zeigen, dass auch dem Lungenmikrobiom eine bedeutende Rolle bei der Regulierung und Aktivität des Lungenimmunsystems zukommt. Das Lungenmikrobiom wurde spät entdeckt, da man lange Zeit davon ausging, dass die Lunge eine pathogenfreie, sterile Umgebung darstellt. In diesem Projekt soll der Einfluss der Lungemikrobioms auf die Schwere einer SARS-CoV-2 Infektion untersucht werden.

Wild animals can serve as reservoir for causative agents of important livestock diseases including African and Classical swine fever, Foot and mouth disease, Bluetongue as well as for zoonotic viruses like SARS coronaviruses, Rabies virus, and Hepatitis E virus. In recent years, a growing number of emerging viruses were identified in domestic and wild animals. These include novel bunyaviruses, reoviruses, astroviruses, birnaviruses, circoviruses and parvoviruses from wild boar detected during the first funding period of VIPER. Another example is the identification of pestiviruses from non-ungulate hosts including rodents, bats, pangolin, and a whale. Further characterization of these newly identified viruses, including studies on viral replication, innate immune responses and other virus-host interactions, depends on successful virus isolation and propagation in tissue culture cells. Preliminary work revealed that the whale pestivirus can efficiently infect swine kidney cells and viral antigen is detectable by a monoclonal antibody. However, for several other viruses virus isolation was not successful. The recent establishment of airway and intestinal epithelial cells organoid cultures from pigs and cattle at our institute can be very useful for isolation and subsequent characterization of selected novel viruses. It is expected that the results of this project will enhance our understanding of viral evolution, origin, cross species transmission and virus-host interactions of human and animal viruses, and thus improve outbreak preparedness and infectious disease control.

Project Details:
Antimicrobial resistance (AMR) is a global challenge worldwide, and generally results from consumption of antimicrobials. Antimicrobial use (AMU) in animal production is part of these processes and has been recognized as a source of global burden of AMR. Surveillance of veterinary AMU and AMR and its reduction is one of the strategic objectives of many regional and global initiatives on antimicrobial resistance crisis. Since, the resistance to critically important antimicrobials like colistin, particularly due to mobile colistin resistance gene (mcr-1), has already been reported in Pakistan from commercial broilers, wild birds and human. Therefore, data on antimicrobial usage and its association with resistance should be prioritized in food animals. Although Pakistan?s National Action Plan on AMR urged to monitor and reduce antimicrobials use and resistance in animals, little effort has been done to curb AMR in food animals. The objective of this project is to quantify AMU in commercial broiler farms in Pakistan and its association with the emergence of AMR in commensal E. coli isolates from broilers. The proposed study will fill the important knowledge gap on the AMU of critical importance antimicrobials in broilers farming, phenotypic antibiotic resistance and genomic characteristics of multidrug resistant E. coli using next generation sequencing approach. The association between AMU and AMR will be determined using statistical approaches. Our work will be an important contribution toward understanding the interplay between AMU and AMR at farms-level in Pakistan and other low- and middle-income countries with comparable farming practices.
This project comes under One-Health remit on antimicrobial resistance and aligns perfectly with the work at University of Veterinary Medicine, Foundation, Hannover which has been also designated as the WHO Collaborating Centre for Research and Training for Health at the Human-Animal-Environment Interface.

The project "DEALS- Decontamination with alternative methods as a hurdle concept on carcasses and cuts of pork, broiler and turkey" investigates the combined application of several innovative decontamination methods in connection with meat production. The aim is to reduce the number of carcasses to be discarded (resource conservation) and to improve or ensure the food safety of the meat (consumer protection). For this purpose, plasma water as well as UV-C treatment, the application of starter cultures and the newer application of plasma water in the form of EWNS (engineeres water nano structures) are to be used. Step by step these decontamination methods will be applied in vitro on pure cultures of relevant microorganisms, on carcass surfaces of pigs, broilers and turkeys, and finally on meat cuts. Within the project, a prototype for the combined application of the methods is to be developed in cooperation with the HAWK, which has already proven itself in another EiP project. The close exchange with the OG partners from the downstream primary production (slaughterhouses) is particularly essential for the practical implementation of the ideas.

It is widely recognised that noise entering the underwater environment from shipping and other human activities can disturb and harm aquatic animals. Studies have already shown these disturbance effects, while other research has suggested ways to reduce some of the noise generated by shipping. However, there are still gaps in our knowledge and understanding of how underwater noise can affect individual animals and entire populations.

This is now set to change with the SATURN consortium, which for the first time brings together leading European experts in bioacoustics, veterinary medicine, population biology, plus naval architecture and engineering in an EU-funded project. Key issues include:
- Identifying sounds that are most harmful to aquatic species and how they are generated and propagated;
- What are the short-term and cumulative long-term negative effects of noise from ships and boats on aquatic species in rivers and the sea;
- What are the most promising options for measuring and reducing the negative impacts of ship noise that can be applied to current and future ships.

Prof. Prof. h. c. Dr. Ursula Siebert, Director of the Institute for Terrestrial and Aquatic Wildlife Research at the TiHo, is the leader of the biological working group in this consortium, which investigates the influence of underwater noise on the behaviour, health and energy balance of aquatic organisms. Another important aspect supported by ITAW is public relations and communication.

The aim of the project is to analyse host-parasite interactions between the Fasciola hepatica as parasite and dairy cows as host, taking into account the genome of both interaction partners. Until now, studies on endoparasite resistance have focused exclusively on the genome of the host or the parasite, without considering genotype-genotype interactions between these two players. Therefore, for the first time, interactions will be modelled considering bovine genotypes (Gh) and F. hepatica genotypes (Gp).

SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus Type 2) is the causative agent of COVID-19. The course of the COVID-19 pandemic so far has emphatically shown that a coordinated bundling of interdisciplinary and complementary expertise is necessary in order to decode the diverse aspects of the biology, pathology and epidemiology of SARS-CoV-2 and to use the knowledge gained clinically for the treatment of patients as well as for modeling the course of infection in the population. In order to be able to provide and implement such a holistic approach, the federal state of Lower Saxony offers ideal conditions with its internationally renowned science locations. We are therefore applying for financial support for collaborative research to set up a COVID-19 research network in the state of Lower Saxony (COFONI).

The retreat of sea ice and the melting and retreat of tidewater glaciers are particularly visible signs of the changes taking place in the Arctic due to global warming. The deterioration of these two physical features of Arctic marine systems is occurring faster in the northern Barents Sea than elsewhere in the circumpolar Arctic, making the Norwegian High Arctic an indicator of climate change in the Arctic region as a whole. The changes will undoubtedly have profound effects on marine ecosystems in the High Arctic and consequences for endemic Arctic marine mammal species.
The ARK research programme will use a variety of data time series (occurrence, ecology, diet, contaminant levels, health parameters, infectious diseases, trophic interactions, etc.) to quantitatively assess different hypotheses on climate change impacts on Arctic marine mammals: 1) Habitat decline will lead to declines in ice-dependent species, changes in distribution patterns and, in the long term, species extinction. 2) Endemic species will increasingly compete with temperate species, which are expanding their habitats. 3) Exposure to new pathogens and increased levels of pollutants will have a negative impact on endemic species. 4) Atlantification of food webs will negatively impact Arctic species and affect the entire Arctic ecosystem.
Within the ARK project, the Kongsfjord, on the west coast of Spitsbergen, will be used in a case-study approach to investigate changes in the ecosystem, apply physical-biochemical food web models and complex risk analyses to make predictions and provide management information.
