Investigation of phages for innovative mitigation of antibiotic use in dairy farming
Untersuchung von Phagen für eine innovative Minimierung des Antibiotikaeinsatzes in der Milchviehhaltung
Project Investigators: Univ. Prof. Dr. Martina Hoedemaker, PhD; Prof. Dr. Madeleine Plötz; Dr. Sophie Kittler; Dr. Elisa Peh; Dr. habil. Nadja Jeßberger
Duration: May 2022 until May 2024
Funding: Milchwirtschaft Niedersachsen e.V. (LVN), 30.000 EUR
Project Details:
Klinische und subklinische Mastitiden führen zu Einbußen in der Qualität und Wirtschaftlichkeit der Milchwirtschaft. Häufig werden Staphylococcus aureus (S. aureus) und Streptococcus
uberis (S. uberis) als Erreger nachgewiesen, durch die Antibiogrammpflicht neuerdings vermehrt auch multiresistente Escherichia coli (E. coli). Der Einsatz von Antibiotika soll in
Hinblick auf die mögliche Verbreitung resistenter und ultiresistenter Erreger so weit wie möglich gesenkt werden. Es wird daher dringend nach alternativen Behandlungsmethoden
mit einer hohen antibakteriellen Wirksamkeit gesucht.
Die Ziele des Projektes sind:
a) Isolierung und Charakterisierung geeigneter Phagen
b) Auswahl von Phagen mit hoher Wirksamkeit gegenüber klinischen
Bakterienisolaten aus der Milchviehhaltung
c) Langfristig soll eine Erhöhung der Wirtschaftlichkeit der Milchviehhaltung dadurch erreicht werden, dass innovative und naturnahe Therapien ohne Wartezeiten entwickelt werden, die die Lieferfähigkeit der Milch nicht beeinträchtigen.
d) Zusätzlich wird mit dem Einsatz naturnaher Alternativen zur Antibiotikatherapie sowie der Verbesserung des Tierschutzes durch wirksame Behandlungsstrategien, dem Wunsch des Verbrauchers nach natürlichen Lebensmitteln Rechnung getragen. Damit liefert dieses Projekt durch Reduktion des Antibiotikaeinsatzes in der Milchproduktion neben der Verbesserung des Tierschutzes auch einen Beitrag zum gesundheitlichen Verbraucherschutz.

In vivo pharmacology of 2nd generation 3CL corona virus protease inhibitors
In-vivo-Pharmakologie von 3CL-Coronavirus-Protease-Inhibitoren der 2. Generation
Project Investigators: Prof. Dr. Asisa Volz
Duration: October 2022 until March 2024
Funding: DZIF, BMBF, 115.000 EUR
Project Details:
The main protease 3CLpro is a prominent drug target to control corona virus (CoV) replication and associated disease. The target is structure-enabled, structurally conserved and believed to offer an opportunity for multi-/pan-CoV-inhibitor designs. Pfizer have received an Emergency Use Authorization for their first-generation 3CL inhibitor Paxlovid. This serves the important clinical target validation for Covid-19 but also demands a differentiation strategy for second generation drugs as outlined herein. We will be applying our University of Marburg (UMR) based mouse transduction CoV challenge model, optimized for SARS-CoV-2 variants-of-concern and the dosing of the herein pursued second generation 3CL inhibitors as designed and synthesized by the Lead Discovery Center (LDC). In addition, the frontrunner compound will be tested head-to-head against Paxlovid in the hamster SARS-CoV-2 disease model maintained at University of Veterinary Medicine Hannover. In so doing we contribute to the preclinical proof-of-concept and hopefully the nomination a lead compound of the second generation 3CLpro inhibitors by LDC.

The return of the Eurasian Otter in Schleswig-Holstein - Investigations on the ecology, potential conflicts with fisheries management and conservation
Die Rückkehr des eurasischen Otters in Schleswig-Holstein - Untersuchungen zur Ökologie, sowie zum fischereiwirtschaftlichen und artenschutzrechtlichen Konfliktpotential
Project Investigators: Prof. Prof. h. c. Dr. Ursula Siebert; Lotte Caecilia Striewe
Duration: May 2022 until October 2024
Funding: MELUND, 749.985 EUR
Project Details:
The Eurasian otter (Lutra lutra) is (re-)expanding in all parts of the German federal state of Schleswig-Holstein (SH) nowadays. As an aquatic mammal, otters mainly inhabit rivers, streams and lakes but also forage along the coastlines. Otters primarily feed on fish, whereas they are considered food generalists and also target amphibians, crustaceans, birds, mammals and other invertebrates. It is assumed that the decline of certain endangeredeD fish species can be linked to the growing otter population. Furthermore, there is an increase in conflicts between fisheries and otter conservation, both nationally and internationally. Therefore, an extensive evaluation of the current conflict potential between the growing otter population, fisheries situation and conservation conflicts between species is needed. This will be covered in the frame of this research project that focuses on fisheries, natural otter habitat and spawning areas of endangered salmonids in comparison:
-Installing wildlife cameras to assess the local abundance of otters
-Dietary analysis to investigate the prey spectrum of otters
-Determination of otter individuals using spraints (genetic fingerprinting)
-Evaluation of a potential conservation conflict between otters and salmonids
-Development of acustic deterrents to protect fisheries from otters
-Analysing reproduction parameters to assess the population health of otters using specimens found dead

Conflict management in the area of fisheries/shellfish farming with eider ducks and health checks of eider ducks
Konfliktmanagment im Begegnungsbereich Fischerei/Muschelzucht mit Eiderenten sowie Gesundheitsuntersuchungen von Eiderenten
Project Investigators: Prof. Prof. h. c. Dr. Ursula Siebert; Luca Aroha Schick
Duration: May 2022 until May 2024
Funding: Ministerium für Energie­wende, Klimaschutz, Umwelt und Natur, 308.493 EUR
Project Details:
Common Eider (Somateria mollissima) is classified as endangered in Europe due to continuous The population declines. Meanwhile, its occurrence along the coast of Schleswig-Holstein has potential for conflict with the culturally established and economically important fisheries.
This pilot study will develop approaches to startle common eiders from mussel farms and allow a sustainable coexistence of conventional fisheries in the Baltic habitat and protected species. The main focus is the protection of mussel farms against common eider predation. However, the results can potentially be transferred to fisheries, to prevent unintentional bycatch of birds in gillnets.
Post-mortem examinations of common eiders will be carried out simultaneously, to find out about potential pathological causes for the population decline and gain an insight into the health status of the population. These examinations include bacteriological, virological and parasitological analyses. Furthermore, toxicological analyses will deliver information about environmental pollution load.

Air filtration in natural ventilated barns in transition periods to prevent from AI entry
Zuluftfiltration in frei gelüfteten Ställen als Übergangslösung in AI-gefährdeten Monaten
Project Investigators: Sake, Björn; Schulz, Jochen; Kemper, Nicole
Duration: June 2022 until May 2024
Funding: Niedersächsische Tierseuchenkasse, 134.050 EUR
Project Details:
The project aims to develope and to evaluate a filtration system that can be used in natural vetilated poultry houses in transistion periods to prevent from AI entries via air. The lifespan of filters, filter efficiencies and the impact of air filtration on the quality of climate in natural ventilated barns are unknown. Therefore, investigations will be conducted at a natural ventilated turkey barn, equiped with a fine dust filtration system.

Development of a turtle-simulator for veterinary teaching purposes using additive manufacturing
Entwicklung eines Schildkröten-Simulators für die Lehre mithilfe additiver Fertigung
Project Investigators: Marie-Therese Knoll; Prof. Dr. Andrea Tipold; Dr.Sandra Wissing; Dr. Johannes Hetterich
Duration: Beginning 2022 until Mid 2024
Project Details:
Bisher existieren in der veterinärmedizinischen Lehre keine 3D- gedruckten Simulationsmodelle für Reptilien. Um die klinische Ausbildung der Studierenden zu verbessern soll ein praxisnahes Schildkröten-Simulationsmodell entwickelt und angefertigt werden. Im Rahmen einer Dissertation soll anschließend evaluiert werden, inwieweit das Modell in der praktischen Anwendung von Studierenden im Rahmen von Wahlpflichtkursen an toten Tierkörpern erfolgreich umgesetzt werden kann.
