The Institute for Terrestrial and Aquatic Wildlife Research supports the University of Aarhus in the implementation and planning of an aerial surveys to estimate abundance of harbour porpoises in the Danish North Sea in the summer of 2023. In June-July 2023, ITAW supports with the selection of survey blocks and the transect design of the surveys to achieve the most complete coverage of the Danish North Sea. ITAW will collect data in five of the seven survey strata in the Danish North Sea in August 2023, and ITAW will analyzing the data to obtain abundance estimates of harbour porpoises. A Partenavia 68 twin-engine aircraft is used as the observation platform. Flight speed during data collection will be 90-100 kn (167-186 km/h) at an altitude of 600 feet (183 m). The study areas are to be covered on one flight day each under predominantly good sighting conditions.

The occurrence of harbor seals in the waters of Schleswig-Holstein has increased in recent years. At the same time, the seals are exposed to an increasing amount of human activity. These include chemical pollution, offshore wind turbine constructions, the Fehmarnbelt crossing, shipping, military and civilian detonations (munitions disposal), fishing, litter, habitat loss and other disturbances such as tourism. The increasing grey seal population in the North Sea has also led to the predation and rape of seals by grey seals in recent years.
As part of this research project, a total of 30 dead seals from the Schleswig-Holstein North Sea and Baltic Sea are to be examined in-depth for their state of health. These 30 individuals will be examined in addition to the 30 seals that will be necropsied as part of the project, which is funded by the Supreme Hunting Authority in the Ministry of Agriculture, Rural Areas, Europe and Consumer Protection of Schleswig-Holstein (MLLEV), bringing the total number of necropsied seals from Schleswig-Holstein to 60. Histological, microbiological and parasitological examinations will be carried out. The parasite fauna and its prevalence provide important information about its influence on the health of the seals. Furthermore, samples that were taken and not examined as part of the necropsies financed by the supreme hunting authority will be taken as part of this research project. This includes, for example, age determination and histological examinations. Furthermore, samples collected during the post-mortem examinations will also be taken for investigations into pollutants, litter, reproductive biology and nutritional ecology and preserved for later projects.
These investigations are to be used in future research projects for development of evaluation parameters of the GES (Good Environmental Status) in the North and Baltic Sea and applied for OSPAR, HELCOM and the Marine Protection Framework Directive.
Overall, the systematic studies of seals are very important in order to fulfill Schleswig-Holstein's obligations under the Trilateral Wadden Sea Agreement, HELCOM and OSPAR.

Project Details:
Antibiotic resistance is a growing public health problem worldwide and particular a challenge in low- and middle-income countries (LMICs). In order to combat antibiotic resistance, it is necessary to address this in line with the One Health approach.
The aim of the project is to develop a harmonized protocol for monitoring data on antibiotic resistance in an integrated One Health approach for humans, animals and the environment and to link the data from all three One Health areas directly with each other. Furthermore, the transmission pathways of antibiotic resistance or resistance genes are to be evaluated in order to be able to take measures against the transmission and development of resistance. Support for the development of international collaboration with cooperation partners from sub-Saharan Africa served to expand cooperation through on-site visits, discussions on currently used protocols and the identification of potential challenges.

Project Details:
Uniferon is an injectable 20% iron dextran for prevention and treatment of anaemia in swine. 200 mg iron is routinely administered to piglets within the first days of life to prevent development of anaemia. Empirical observations show, that iron deficiency can develop within the first four weeks of life despite this early preventive measure due to the high growth rates of modern cross-bred pigs. While the product Uniferon can be used in flexible volumes, so that an adaptation of the iron amount administered is possible, the competitor product Forceris can only be used in a fixed dosage of 1.5 ml containing 200 mg iron -gleptoferron in combination with 45 mg toltrazuril as a coccidiostaticum. The advantage of this combinatory product to address two different diseases by one single shot is counteracted by the lack of adjustment of the necessary amount of iron to prevent anaemia as long as possible. Different iron treatments in suckling piglets should be evaluated to review the traditional recommendations for iron applications and adjust them according to the higher genetic potential for growth in modern pig breeds if necessary.

In May 2022, an unprecedented multi-country outbreak of monkeypox affecting Europe, North America, the Middle East, and Australia was recognized. Monkeypox (MPX) is a re-emerging, zoonotic, and potentially life-threatening viral disease caused by monkeypox virus (MPXV), an orthopoxvirus endemic in Central and West Africa. As of June 28th 2022, a total of 4119 confirmed cases have been reported worldwide (ECDC), including 676 confirmed cases in Germany (RKI). This is the first time that chains of human-to-human MPXV transmission are documented without epidemiological links to West or Central Africa. At present, most cases are detected in young men, self-identifying as men who have sex with men, and associated with mild clinical symptoms. However, MPXV may cause severe disease in risk groups of the population (young children, pregnant women, immunosuppressed persons), and a spread of MPX into the general population is to be expected as most of the younger population (<50-60 years of age) lack virus specific immunity because of the end of smallpox vaccination programmes in the 1980ties. Thus there is a risk of an extended period of MPX circulating also outside of Africa, and ongoing efforts in the public health response must interrupt MPX transmission chains and clear MPXV from its new environment as soon as possible. Current countermeasures include the use of a licensed smallpox vaccine (IMVANEX) based on Modified Vaccinia virus Ankara (MVA) and a licensed drug against smallpox (Tecovirimat). STIKO recommends vaccination with IMVANEX as post-exposure prophylaxis for contacts of MPX patients and for persons at high risk of exposure.
The aim of this application is to support this counteraction measures against the MPX outbreak by preparing for the development and clinical use of the DZIF MVA-SARS-2-S candidate vector vaccine as bivalent vaccine against MPX and COVID-19 including the establishment of a preclinical model for immunogenicity and efficacy testing.

Project Details:
Entomophagy has traditionally been practised in many regions and is now gaining popularity in Europe. Commercial production reduces the burden on wild populations, ensures safety and quality and generates new streams of income. However, like all other domesticated animals, insects reared in large quantities need oversight to ensure animal welfare and health. This does not happen yet.
The aim of this project is therefor to train students of veterinary and biological sciences to work in this field. As an elective module veterinary students learn how to care for and assess insect rearing, while students of biology learn to how to identify edible insect species. Students will raise their own insect charge and will become a potential advisor for farmers interested in commercial insect rearing.

The FBF funded project "Influence of stress during rearing management and later eligibility in sperm production" revealed a clear difference in a developed management score and in mean testosterone concentrations between young bulls with good versus poor sperm quality. However, due to a lack of sensitivity, hormone measurements could not be used as adequate diagnostic tests to identify very good or bad bulls with regard to their later performance and performance persistence, neither at an age of four months nor later at the first semen collection.
This more in-depth study is designed to search for better biomarkers using proteomics as non-target approach. Bulls with a very good versus bad performance persistence over two years will be analyzed by mass spectrometry using the plasma samples collected close to the first semen collection during the preliminary project. Data sets of the mass spectrometric measurements with identified peptides will be matched with a bovine protein database to finally name proteins of the plasma samples. Both groups of bulls will be compared with respect to the proteins identified and the amounts of the same.
In order to establish test methods that are as practicable as possible, promising fertility-associated proteins will subsequently be measured in the blood samples from all age classes investigated during bull calf rearing using commercially available ELISA kits. These data will be used to establish reference ranges and thresholds using receiver operating characteristic (ROC) analyses. Optimally, suitable biomarkers in the blood allow an early preselection of bull calves that are eligible for the collection of quantitatively and qualitatively good semen.

For these project dead found seals, stranded at the polish coast, will be collected.
Within the scope of this project the ITAW will conduct health investigations of the stranded seals.
In the course of these investigations ITAW researchers will perform pathological examinations of internal organs and analysis of reproductive organs. The species of parasites the marine mammals potentially are infected by will be identified. Their age will be estimated and histological, virological and microbiological analysis conducted. So health reports based on postmortem analysis for each investigated animal will be prepared.
