Project Details:
As part of the SeroFaSt - Mhyo project, a serological on-farm rapid test for the detection of
Mycoplasma hyopneumoniae infections in pigs. This test is intended to
differentiate between vaccinated and infected animals directly on the farm,
without the need for time-consuming and cost-intensive laboratory tests. The rapid identification of
infected animals should enable immediate, targeted treatment and thus lead to greater animal welfare and
and better consumer protection.

Project Details:
The aim of the project is a survey of the local grey seal population in the entire Lower Saxony and Hamburg Wadden Sea during the birthing season (November-December) 2023 and at the time of the fur change (March-April) 2024.
On five trilaterally coordinated dates (three during the birthing season; two during the fur-change period), airborne surveys will be conducted with a single-engine aircraft. During the aerial surveys of the tidal flats, a high-resolution SLR camera will be used to photograph the haul-outs. In order to determine the number of young born as well as the total population, the photos taken are subsequently analyzed on the computer.

Project Details:
In this project, the population of harbor seals and grey seals will be surveyed over a period of 12 months (2023-2024) to assess their abundance and distribution in the Tidal Elbe area. The aerial surveys of the seal population in the Elbe estuary will take place from August 2023 to July 2024. During the flight along all known and potential haul-out sites, images will be taken with a high-resolution digital SLR camera and subsequently analysed. This conversion to the photo-based method was successfully carried out in previous projects and innovatively further developed in order to be able to provide the client with reliable figures and the highest possible transparency as well as reproducibility of the results.

Project Details:
On behalf of the University of Aarhus (Denmark), data from observer-based aerial survey flights to determine the abundance and distribution of small cetaceans in the southern Danish North Sea will be analyzed. The main target species is the harbor porpoise (Phocoena phocoena). The aerial surveys are conducted following line-transect survey methodology and data will be collected according to the so-called SCANS protocol. The data are expected to come from at least three surveys in May, June and October 2023. ITAW has been commissioned to perform quality assurance and analysis of the collected data. Densities and abundances of harbour porpoises will be estimated for each survey and the inaccuracies (95% confidence intervals and coefficient of variation (CV)) associated with the estimation will be determined. The processed data and results will be submitted to the client.

Results:

engl.: For the surveys of the study area in the southern North Sea, densities and abundances of harbour porpoises were estimated and the inaccuracies (95% confidence intervals and coefficient of variation (CV)) associated with the estimation were determined. The processed data and results were submitted to the client.

Project Details:
Studierenden der Tiermedizin soll eine Kategorisierungsstrategie für die Haltungsumgebung und Erkrankungen von Schweinen bereits in den ersten beiden Fachsemestern vermittelt werden, um in den späteren Semestern erworbenes Wissen zur Nutztiermedizin besser einordnen und damit besser lernen zu können. Damit wird auf fehlendes landwirtschaftliches Vorwissen der Studierenden und auf den Mangel an Nachwuchs für die Nutztiermedizin reagiert. Die Lehreinheit fokussiert sich auf die technischen Bedingungen in der Stallumgebung (z.B. Fütterungstechnik, Bodenbeschaffenheit), welche die Tiergesundheit maßgeblich beeinflussen. Diese bleiben den Studierenden bisher besonders fremd, sofern sie nicht auf einem landwirtschaftlichen Betrieb aufgewachsen sind. Es sollen dafür vier unterschiedliche Haltungssysteme für Schweine als 360°-Rundgänge gefilmt, für die interaktive Tourengestaltung vorbereitet und mit Informationsmaterial hinterlegt werden. Dazu wird jeweils ein klinischer Fall so aufgearbeitet, dass nur ein offener Blick sowie technischer und biologischer Grundverstand, der ab Studienbeginn vorausgesetzt werden kann, nötig sind, um die Arbeitsaufgabe im Sinne einer Schnitzeljagd zu lösen, bzw. das Grundproblem zu identifizieren. Alle Informationen, die darüberhinausgehend benötigt werden, um den Fall zu lösen, werden an Infopunkten zur Verfügung gestellt. Die Lernkontrolle erfolgt anhand eines weiteren Falls in einer der virtuellen Stallumgebungen ohne Infopunkte und wird asynchron durch den Lehrenden bewertet.

Project Details:
Every year, about 750,000 people die from mosquito-borne diseases, including malaria, dengue fever, rift valley fever and chikungunya fever. The incidence of these diseases is expected to increase significantly over the next few decades, as the ranges of several mosquito species are expanding due to climate
change. Mosquitoes not only transmit diseases, but can also influence the severity of the diseases they transmit. It has been shown in experimental infections of animals, the transmission of arboviruses by mosquito bites compared to artificial infection can lead to an increase in the severity of the disease. In
addition, it is known that the saliva of insects and ticks can promote the progression of vector-borne diseases. The skin is the first organ to be exposed to an arbovirus infection, thus the initial infection events also significantly determine the course of the disease. It is therefore essential for many to investigate a natural infection of the skin via a mosquito bite. So far, this could only be achieved by in-vivo experiments (animal experiments). In this project, an alternative is to be developed by replacing animal models with human skin explants for ethical and physiological reasons. The challenge of this study will be to establish an assay in which mosquitoes can use the skin implants as potential hosts. The goal is a successful biting of the skin explants by mosquitoes. Exemplarily, in a second step the skin explants should be infected via bite of Rift Valley Fever Virus (RVFV) and/or Chikungunya Virus (CHIKV)-infected mosquitoes. If
successful, the project results will allow to choose from different models for future research questions.
