Ermittlung des Schallpegels in der Ferkelaufzucht mit Bezug zu Tier- und Arbeitsschutz
Project Investigators: Kroll, Laura; Fels, Michaela; Kemper, Nicole
Duration: May 2021 until Novemer 2022
Funding: QS-Wissenschaftsfonds, 30.000 EUR
Project Details:
The aim of this study is to determine the sound level in pigs' nursery compartments and to detect the effects of animal behaviour and barn technology on the sound level.
In addition, occupational safety will be considered in the study by identifying particular sound events to which both, animals and humans are exposed, and quantifying them with regard to the sound pressure level. The aim is to generate representative data on noise pollution in today's piglet rearing in Germany, to determine the origin of noise pollution and - if necessary - to identify potential for improvement in terms of animal welfare and occupational safety.

Detection Dogs as first line screening method for SARS-CoV-2-infections
Detection Dogs as first line screening method for SARS-CoV-2-infections
Project Investigators: Holger Volk; Friederike Twele; Claudia Schulz
Duration: September 2021 until September 2022
Funding: COVID 19 Forschungsnetzwerk Niedersachsen COFONI, 48.638 EUR
Project Details:
Early detection of individuals with a SARS-CoV-2 infection remains the most important tool to interrupt the chain of infection. Several studies have already proven canines? extraordinary olfactory acuity to detect SARS-CoV-2-infected individuals. However, with increasing knowledge about the virus, the variety and chronicity of the disease expression and an increase in the number of people that are vaccinated, some questions have not yet been answered. We will test a variety of hypotheses to further explore the use of detection dogs as a screening method for SARS-CoV-2-infections.
Results:

Dogs can distinguish SARS-CoV-2-infections from other viral infections. However, compared to earlier studies our scent dogs achieved lower diagnostic sensitivities. To deploy COVID-19 detection dogs as a reliable screening method it is therefore mandatory to include a variety of samples from different viral respiratory tract infections in dog training to ensure a successful discrimination process.

Evaluation of MVA MERS S immunogenicity and protective efficacy in dromedary camels
Evaluierung von MVA MERS S hinsichtlich Immunogenität und protektiver Wirksamkeit in Dromedaren
Project Investigators: Prof. Dr. Asisa Volz; Prof. Dr. Wolfgang Baumgärtner
Duration: January 2021 until April 2022
Funding: BMBF, 95.000 EUR
Project Details:
Das MERS-CoV (Middle East Respiratory Syndrome Coronavirus) ist die Ursache einer schweren und oft auch tödlich verlaufenden Atemwegserkrankung beim Menschen. Da das Virus natürlicherweise im Dromedar zirkuliert, welches vor allem auf der Arabischen Halbinsel ein sehr bedeutsames Nutztier mit engen Kontakt zum Menschen ist, stellt das Virus eine große Herausforderung als zoonotisches Pathogen dar. Dromedare scheiden das Virus in großen Mengen mit Ex- und Sekreten aus, sodass eine Übertragung auf den Menschen sehr produktiv ist, wohingegen die Mensch-zu-Mensch-Übertragung weniger epidemiologisch bedeutsam ist.
Um die derartige Infektionskette zu unterbrechen und um den Menschen vor einer Infektion zu schützen, ist es demnach von Bedeutung, die Virusausscheidung des natürlichen Virusreservoirs und damit des Dromedars zu verhindern. Die hierbei vielversprechendste Methode scheint die wirksame Vakzinierung des Dromedars als natürlicher Viruswirt zu sein.
Bei dem zu untersuchenden Impfstoff handelt es sich um MVA-MERS-S. Hierbei wird das Gen des S Proteins von MERS-CoV in das Genom von MVA (Modifiziertes Vaccinia Virus Ankara) eingebaut, sodass dieses replikationsdefiziente und als sicher getestetes Vektorvirus das MERS CoV S Protein exprimiert und so voraussichtlich zu einer Immunität des Dromedars gegen MERS CoV führt.
Das Ziel des Projektes besteht darin, die Immunogenität und protektive Wirksamkeit des Impfstoffes im Dromedar zu überprüfen. Dabei wird die bestwirksamste Applikationsroute des Impfstoffes ermittelt, das Level und die Langlebigkeit der Immunantworten (inklusive T Zellen), welche aufgrund der Vakzinierung induziert werden, charakterisiert und letztlich die Fähigkeit des Impfstoffes eine Virusausscheidung zu verhindern, untersucht.

Possibilities and limits of salt reduction in raw fermented sausages and cured cooked products
Möglichkeiten und Grenzen der Salzreduktion in Rohwurst und Kochpökelware
Project Investigators: PD Dr. Carsten Krischek; Prof. Dr. Madeleine Plötz
Duration: January 2021 until December 2022
Funding: Drittmittelprojekt, gefördert durch die Fritz-Ahrberg-Stiftung., 46.000 EUR
Project Details:
The reduction of the salt content is a regularly discussed topic in recent years, which should be considered by the food processing industry, for example through a reduction or the replacement of sodium chloride with other substances such as potassium or magnesium chloride. In addition to the sensory properties that are mainly perceived by consumers, however, technological and microbiological parameters are also important. The aim of this study is therefore to produce raw sausages and cooked cured meats both with reduced sodium chloride concentrations and with the addition of potassium and magnesium chloride and to analyse both the sensory and other parameters. The aim is to show which (minimum) concentrations of sodium chloride or salt substitutes can be used to produce products that are acceptable for consumers in terms of food quality and, in particular, safety.

Infection of intestinal cells by SARS-CoV2 and its effects on intestinal function
Infektion von Darmzellen durch SARS-CoV2 und Auswirkungen auf die Darmfunktion
Project Investigators: Prof. Dr. Hassan Y. Naim
Duration: April 2021 until September 2022
Funding: Deutsche Forschungsgemeinschaft (DFG), Bonn plus ein Doktorandenstipendium (HGNI, 1 Jahr, je 1300 ?), 75.850 EUR
Project Details:
CoVid-19 is characterized by infection of the airways by SARS-CoV-2. Apart from the respiratory tract, other organs are also involved, e.g. the intestinal tract. The importance of the intestinal infection is increasingly recognized. In a large proportion of pediatric patients, virus was detected in rectal swabs and virus shedding from the intestine was found even when oral swabs had become negative. Therefore, prolonged virus shedding and fecal-oral transmission have to be considered. This notion is supported by detection of the virus in wastewater.
The aim of this short project is to apply intestinal cell cultures to characterize the infection of differentiated intestinal epithelial cells by SARS-CoV-2 and thereafter intestinal orgranoids.
This in vitro infection approach will target the following aims:
1. Characterization of the replication efficiency of SARS-CoV-2 (virus yield, virus exit, virus entry, apical, basolateral).
2. Localization of the cellular receptor(s) in human intestinal Caco-2 cells
3. Investigation of the trafficking of the cellular receptor(s), determination and subsequent modulation of their mode of interaction with membrane microdomains (lipid rafts, LRs)
4. Effects of glycosylation modulators on the spike glycoprotein and its interaction with intestinal cells
5. Implication of virus infection on the trafficking and function of crucial enzymes of the intestinal physiology (APN, SI, LPH, DPP4).
This project will provide substantial information on the replication of SARS-CoV-2 in intestinal epithelial cells, evaluate its effects on the intestinal function and provide solid hypotheses on the molecular and biochemical basis for the symptoms elicited by SARS-CoV-2 infections. These hypotheses can be then examined at a later stage in intestinal organoids. Further, unravelling the biosynthetic pathway, glycosylation pattern and mode of interaction of the SARS-CoV-2 receptors and its modulation could constitute exquisite targets for potential therapy.

COVID-Protect - Efficacy of Nrf2 activators for preventing cell injury in COVID-19 - Subproject toxicity and efficacy studies
COVID-Protect - Wirksamkeit von Nrf2 Aktivatoren für die Verhinderung von Zellschädigung bei COVID-19 - Teilprojekt Toxizitäts- und Wirksamkeitsstudien
Project Investigators: Prof. Dr. Gisa Gerold
Duration: July 2020 until June 2022
Funding: BMBF, 261.911 EUR
Project Details:
Inflammation and associated lung injury, such as the acute respiratory distress syndrome (ARDS) are major causes of morbidity and and mortality in COVID-19. The Nrf2 transcription factor activates a comprehensive cell-protective and anti-inflammatory program. It is known from mouse models that pharmacological activation of Nrf2 and induction of this program protects animals from LPS-induced ARDS. In a cell line-based screen for agents against COVID-19, we found 2 Nrf2 activators that prevent the cytopathic effect of SARS-CoV-2 at nontoxic doses. Therefore, the aims of the present project are,
- the establishment of infection models based on
human respiratory epithelial cells, a model for the alveolar
epithelial cell barrier, and ex vivo culture of lung explants,
- Evaluation of the importance of the endogenous Nrf2 program for
the cellular response against SARS-CoV-2, and
- Verification of the 2 identified Nrf2 activators and
identification of additional protective agents via a
comprehensive screening of known Nrf2 activators.
