The role of ANTi-RVFV Immunity in GermliNe infection and bEhavior modulation in insects (ANTIGoNE) 2: CNS infections and behavioural changes in insects
The role of ANTi-RVFV Immunity in GermliNe infection and bEhavior modulation in insects (ANTIGoNE) 2: CNS infections and behavioural changes in insects
Project Investigators: Michael Stern
Duration: Novemer 2019 until October 2023
Funding: DFG STE 1428/5-2, 191.719 EUR
Project Details:
Arboviruses are transmitted between vertebrate host and arthropod vectors. Many of these viruses cause neurological defects or abortions in mammalian hosts. However, infection phenotypes in insects are not well characterized. The insect immune response to these arthropod-borne (arbo) viruses is key to keep infected insects sufficiently healthy to enable host finding and production of offspring, two of the major influencing factors for virus transmission. The insects' immune system relies mainly on antiviral RNA interference to combat a larger variety of different viral pathogens. This RNAi mechanism is initiated by the recognition and cleavage of double-stranded (ds) RNA by the RNAseIII enzyme Dicer-2 (Dcr-2) which then leads to degradation of intruding viral genomes by the RNA-induced silencing complex (RISC) including the Argonaute 2 (Ago2) protein. Furthermore, piRNA pathways are active in the germline cells to protect genomes form massive disruption through movement of transposable elements. In the past years, also piRNAs originating from arbovirus genomes were described raising the question of their role in insect’s immune responses. Pi and siRNA responses in germline tissues are of special interest in arbovirus infection since many of those viruses are transmitted vertically within a mosquito population. Especially viruses of the order Bunyavirales are efficiently transmitted through the germline to mosquito offspring without affecting the health of mosquito offspring. In contrast, the transmission of bunyaviruses to the offspring of mammals leads to severe abnormality in fetus development and often results in abortion. This raises the question how insects keep the delicate balance of allowing viral replication and the protection of offspring health to allow transovarial transmission. Furthermore, pathogen infection in mosquitoes can induce behavioral changes; for example Aedes triseriatus mosquitoes infected with La Crosse virus (Bunyaviridae) show a higher probing frequency than uninfected siblings and Zika virus (Flaviviridae) infection on neuronal cells increases neuronal activity in Aedes aegypti. These observations raise the question: By which mechanisms do arboviruses affect neuron function in insects (direct damage to neurons by infection or indirect damage by immune pathway activation).To tackle both questions, we will use the infection models for Rift valley fever virus (Bunyaviridae, RVFV) in the model insect Drosophila melanogaster and measure virus growth in different tissues, immune reaction in germlines and neuronal tissues and behavior in infected individuals by a different behavioral assays and electroantennograms. The proposed studies will help us to analyze adaptive changes in insects host seeking behavior and the underlying molecular mechanisms as well as the role of antiviral pathways in infection of germline cells.

Influence of "vaginal seeding" on early calf health

Duration: Beginning 2018 until December 2023
Funding: Gesellschaft der Freunde, 18.000 EUR
Project Details:
In human medicine caesarean section seemed to be a risk factor for the development of immunologic and metabolic diseases in children, which can be partially counteracted with "vaginal seeding", the exposure of the offspring to maternal vaginal fluids directly after caesarean section. The aim of this study was to investigate the effect of "vaginal seeding" on early calf health born via caesarean section.

Development of the prerequisites for a national animal welfare monitoring. Selection and testing of suitable indicators for important terrestrial and aquatic farm animals for husbandry, transport and slaughter. Preparation and publication of a prototype for a monitoring report
Entwicklung der Grundlagen für ein nationales Tierwohl-Monitoring der Nutztierhaltung in Deutschland. Auswahl und Erprobung von geeigneten Indikatoren für die wichtigsten Nutztiere für Haltung, Transport und Schlachtung. Erstellung und Veröffentlichung eines Prototyps für einen Monitoring-Bericht
Project Investigators: Jung-Schroers, Verena
Duration: December 2018 until July 2023
Funding: Bundesanstalt für Landwirtschaft und Ernährung, 290.391 EUR
Project Details:
Tierwohl in der Nutztierhaltung ist ein kontrovers diskutiertes Thema. Gleichzeitig ist die Informationslage zum Stand des Tierwohls äußerst gering. Daten zu tierbezogenen Indikatoren für alle relevanten Gesundheitsbereiche (z.B. Lahmheiten, Verletzungen), Tierverhalten und Emotionen, zu ressourcenbezogenen Indikatoren (z.B. Platzangebot, Haltungsverfahren) und managementbezogenen Indikatoren (z.B. Eingriffe an den Tieren, Fütterung, Dauer der Säugeperiode) liegen kaum bzw. nur vereinzelt und nicht systematisch erhoben, vor. Zwar werden für die terrestrischen Nutztiere einige Daten, aus denen sich Aussagen zum Gesundheitsstatus der Tier und zu einzelnen Aspekten des Tierwohls ableiten lassen, regelmäßig erhoben (z.B. Schlachtbefunde, Antibiotikaverbrauch, Herkunftssicherungs- und Informationssystem für Tiere, Milchleistungsprüfung), sie können bisher aber nicht systematisch und im Zusammenhang ausgewertet werden. Gründe hierfür sind, dass die Daten nicht standardisiert erhoben werden und dadurch nicht vergleichbar sind, nur bestimmte Produktionsrichtungen und Tierarten erfasst werden oder keine Rechtsgrundlage für eine Tierwohl-bezogene Auswertung vorliegt. Ziel des Projektes ist es, die Grundlagen für ein regelmäßiges, indikatorengestütztes Monitoring und eine Berichterstattung über den Status des Tierwohls in der Nutztierhaltung in Deutschland sowie dessen Veränderung über die Zeit zu erarbeiten. Dieses Tierwohl-Monitoring soll die verschiedenen Dimensionen des Tierwohls in den relevanten Lebensabschnitten der Tiere (Haltung, Transport, Schlachtung) berücksichtigen. Neben den wichtigen terrestrischen Nutztieren (Rinder, Schweine, Geflügel) wird auch die Aquakultur einbezogen.

Diagnostic imaging and therapy of pelvic-femoral disorders in horses.
Bildgebende Diagnostik und Therapie von Erkrankungen im Beckenbereich bei Pferden.
Project Investigators: Prof. Dr. F. Geburek; Dr. M. Hellige; Dr. Fay Sauer, PhD; Prof. Dr. P. Stadler; Prof. Dr. A. Beineke
Duration: January 2001 until December 2023
Project Details:
Erkrankungen der Beckenregion des Pferdes stellen u.a. aufgrund der starken Bemuskelung dieser Region und der Unzugänglichkeit einzelner Strukturen oft eine diagnostische Herausforderung dar. Zum Teil ist die Wertigkeit von klinischen und bildgebenden Befunden im Beckenbereich hinsichtlich ihrer Bedeutung als Lahmheitsursache unklar.
Pferde mit Erkrankungen der Beckenregion (d.h. des knöchernen Beckens, der Beckengürtelmuskulatur, des Hüftgelenks, des Kreuz-Darmbein-Gelenks, des Lumbosakral-Gelenks) werden klinisch, ggf. mittels diagnostischer Betäubungen, ultrasonographisch und röntgenologisch untersucht. Es erfolgt eine vergleichende Auswertung der bildgebenden Befunde hinsichtlich ihres diagnostischen Wertes, ggf. unter Einbeziehung von Sektionsbefunden. Die Erkrankungen werden falls möglich medikamentell oder anderweitig behandelt, und der Behandlungserfolg wird langfristig nachverfolgt.
