Due to the frequent use of antibiotics, there are more and more diseases caused by resistant germs in both human and veterinary medicine. Unfortunately, more and more germs on our dogs' skin are showing this problem, so that skin infections that were previously easy to treat are now difficult to treat. Therefore, alternatives to antibiotics are increasingly being sought. A team led by Dr. Jessica Meißner from the Institute for Pharmacology, Toxicology and Pharmacy at the Hannover University of Veterinary Medicine Foundation is now checking whether products based on manuka honey or ozone oil can help in the fight against multi-resistant skin germs (especially Staphylococcus pseudintermedius) in dogs.

The cHillYGIENE project will be carried out in three stages. First, the microbiological contamination of cooling fan units and their surroundings in meat processing plants will be investigated, while simultaneously recording various metadata (including design, materials, temperature range, operating zones, defrosting processes, and refrigerated goods). This will be done through a broad-based status quo survey and long-term monitoring in selected companies. This will provide comprehensive information on the usual microbial colonization, hygienically relevant areas, and the development of microflora in air coolers. Furthermore, the influence of various surface coatings on relevant cooling fan components on microbial contamination is being investigated. Preliminary laboratory-scale tests provide basic information on the extent to which coatings influence the adhesion, detachment, proliferation, and biofilm formation potential of selected microorganisms under practical conditions. Based on this, the previously identified hygienically relevant components of a standard cooling fan are coated, or coated pieces of material are installed in them as sentinels. The modified cooling fan is installed in a practical operation or in a room suitable for simulating practical conditions in order to generate information on the hygienic benefits of surface coatings on cooling fans. Finally, the results are evaluated jointly and discussed with the participating commercial enterprises. Based on the synthesis of all available data, the final report identifies problems and formulates recommendations for implementing the results in practice.

The protozoan parasite Toxoplasma gondii is capable of being transmitted to humans via under-cooked meat or contaminated raw foods and has been identified as a potential health risk to the immunocompromised and pregnant population. In the absence of an efficient, rapid test method for foodstuffs that enables early identification of the source of contamination, work is underway on the development of a LAMP assay, with funding provided by the Fritz Ahrberg Foundation. This method should enable the rapid and sensitive detection of even small amounts of parasites in various, sometimes complex food matrices. In a subsequent phase of the project, the presence of pathogens along the food processing chain will be determined. Consequently, potential measures for risk minimisation can be evaluated.

This project aims to develop a system for the visualization and modification of carbohydrate structures on the surface of neuronal cells within 3D neurosphere models. By employing chemically modified sugar derivatives and bioorthogonal ligation chemistry, surface epitopes will be selectively labeled and functionalized for fluorescence imaging. This approach enables the investigation of changes at the cell surface during early brain development in a complex, biomimetic system that recapitulates fetal brain development. The innovative strategy holds the potential to significantly deepen our fundamental understanding of the role of glycans in neuronal development. In the long term, this technology could advance research into the impact of infections on the developing brain and may open new avenues for preventive strategies to reduce the risk of neurological sequelae and neurodevelopmental disorders following fetal infections.

The planned project will serve to prepare a multilateral project proposal on research and innovation at EU level in order to improve the integration of Eastern Partnership countries into the European Research Area.
The multilateral AgriTransEUROPE consortium consists of six excellent research groups from two
European Member States (D, NL) and three Eastern Partnership countries (GE, UA, ARM). The planned
EU application aims to provide alternative treatment strategies that can replace or complement current antibiotic treatments. The aim is to further develop the use of bacteriophages as a model in the three animal husbandry systems poultry, cattle/pigs and aquaculture. Bacteriophages are viruses that can infect and kill bacterial pathogens. The planned project aims to address global challenges in the food and livestock sector with innovative concepts for the use of bacteriophages.

Project Details:
Gaining knowledge about the anatomy and physiology of the forestomaches of ruminants is an important part of veterinary education. This sets the basis for proper diagnosis of diseases and surgical interventions on this organ system in their future professional practice. During their preclinical study part at the University of Veterinary Medicine Hannover, Foundation (TiHo), all veterinary students attend certain anatomical and physiological practical courses related to this topic. These courses also include the work with living animals, hence defined as animal experiments. However, the goal of thorough and sustainable veterinary training, conflicts with the raising legal and public pressure to reduce the number of animal experiments and desired improvement of animal welfare. This project aims to develop a virtual anatomical model of the ruminant forestomaches to be implemented into the Virtual Learning Lab of the Clinical Skills Lab (CSL). This virtual resource can be accessed by all students online at any time, providing flexible learning opportunities. According to the 2022 teaching report, students rated the opportunities for deepening their knowledge at the CSL very positively and expressed a desire for additional offerings that allow for independent and needs-based learning of practical, job-relevant skills. Therefore, a second aim of this project is the development of a malleable 3D model of the rumen, simulating its motility and allows for manual palpation of the organ. Simulations play an important role in medical education and are assessed as very useful by the students when linked to practical relevance. The planned project ranges within the framework of the 3Rs concept for animal experiments providing both, a refinement and a reduction method. Using the simulator, students can learn how to palpate the rumen before they do it on a living animal during the practical course. This helps to reduce anxiety and leads to a more skilled and animal-friendly handling. The virtual forestomach model offers the opportunity for independent preparatory learning and thus contributes to reduce the number of animals used in the anatomical practical courses. During the clinical study phase, both models can be used for repetition of anatomical and physiological basics to support final exam preparation and the acquisition of clinical and surgical skills. Therefore, both models can be used across semesters, promoting the development of learning- and career-related skills and competences.

Project Details:
The protozoan parasite Toxoplasma gondii is the causative agent of toxoplasmosis, a zoonosis that can be transmitted to humans by infected cats or through the consumption of contaminated foodstuffs or inadequately heated meat from infected intermediate hosts. Primary infections during the early stages of pregnancy are of particular concern due to the absence of maternal immunity, which allows the pathogen to cause severe foetal damage and abortions. There is currently no comprehensive and systematic monitoring of the pathogen in the food chain in Germany. Moreover, the accessibility of the pertinent testing methodologies is constrained. The project therefore aims to develop a rapid, field-proven detection method based on the loop-mediated isothermal amplification (LAMP) technique and to corroborate its validity for pertinent food matrices. Thereafter, the method will be employed to appraise the impact of diverse manufacturing techniques employed on sample products on the pathogen load, and to extrapolate recommendations for industrial manufacturing processes.
