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:
The two invasive fungi Batrachochytrium dendrobatidis (hereafter referred to as Bd) and B. salamandrivorans (hereafter referred to as Bsal) originate from Asia. Bd is known to infect more than 700 species of amphibians of all three clades (caecilians, salamanders, frogs). A Bd infection can lead to clinical disease and ultimate death of affected animals. Clinical disease though, like the characteristic skin lesions, are not present in all cases. The so-called chytridiomycosis is therefore versatile and difficult to predict. Bsal was first discovered in Europe in the Netherlands in 2013, where the pathogen has been associated with a decline of more than 95% of the fire salamander (Salamandra salamandra) population since 2010. Since then, outside of Asia, it was found in several European countries, including Germany. The overall aim of the project is to provide better knowledge of the actual distribution of both invasive fungi Bd and Bsal in Schleswig-Holstein over a period of two years. Therefore, different amphibian species sharing the same habitats in Schleswig-Holstein are targeted. Sampling uses sterile skin swabs, which represents an amphibian friendly method. Right after sampling, animals are released. Ideally, the outcome of this pilote study will give first ideas of regional, seasonal and species specific characteristics of the pathogens and will thus shape future research in this field.

The following questions will be addressed:
-Is there a direct link between the detection of Bd and Bsal and clinical symptoms or even an increased mortality?
-Which species typically show symptoms of clinical disease? Which species
are infected without symptoms (subclinically), function as asymptomatic carriers or as a reservoir?
-Are there regional differences in the prevalence of the pathogens?

Due to the critical situation of Schleswig-Holsteins amphibians, it is of utmost concern to apply management measures to protect amphibian populations of additional threats like infectious diseases. Additionally, the outcome of the project will therefore directly serve conservation efforts and help improve reintroduction efforts and management measures for amphibians.

Project Details:
Enteropathogenic Bacillus cereus are responsible for a diarrhoeal type of food poisoning. In earlier studies, we could show that milk inhibits the toxic activity of B. cereus enterotoxins towards human colon epithelial cells. At this, caseins as well as lactoferrin seem to hinder the interaction between the single toxin components. In this project, the influence of lactoferrin on growth and enterotoxin production of different B. cereus isolates is tested at first. Strain-specific differences are made visible, as well as the influence of different lactoferrins and their derivatives. The molecular mechanisms underlying the enhanced enterotoxin production after lactoferrin exposure are investigated via RNA sequencing. It is further tested which genes are up- or downregulated under iron deficiency and especially after lactoferrin contact. This gives an overview on the transcriptional changes in the organism. The second point is the detailed investigation of the inhibiting effect of lactoferrin towards the B. cereus enterotoxins in cell culture systems. For this, different commercially available lactoferrin products and derivatives will be tested, as well as their impact on different B. cereus toxins such as haemolysin BL, the non-haemolytic enterotoxin, cytotoxic K and the emetic toxin cereulide. Finally, the issue of lactoferrin-sensing and motility (chemotaxis) of selected B. cereus strains will be investigated. Next to the general ability of active movement, it will be tested if lactoferrin has a repelling or attracting effect on a certain isolate.

Recent studies show that after processing pork and turkey meat frozen stored at -80°C for up to 48 weeks to raw sausages, red values of the sausages were higher and aw values lower compared to unfrozen or at -18°C frozen stored meat samples. These results suggest that when producing products from such frozen meat, the concentrations of cooking salt and nitrite salts might be reduced, as red values and aw values would change in the opposite sense when salts are reduced. However, a reduction of common salt and nitrite salts must be proportionate, as the shelf life and texture of the products could be changed. In the study, meat from beef, pork, chicken and turkey is therefore stored for 24 weeks at -18°C and -80°C and, after thawing, processed into raw and cooked sausages with reduced NaCl and nitrite concentrations. The meat products are analysed microbiologically, sensory and physicochemically during maturation and further storage in a protective gas atmosphere.

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.

Ausbildungsforschung der Stiftung Tierärztliche Hochschule Hannover soll die
aufgrund der COVID-19-Pandemie eingesetzte hybride Form der universitären Lehre
auf ihre Nachhaltigkeit und die Übertragbarkeit auf vergleichbare Situationen

Präsenzlehre verglichen werden. Im Fokus dieser Arbeit stehen das Wintersemester
2020/2021 sowie das Sommersemester 2021. Die hybride Form wird hier als
Kombination aus Präsenz- und digitaler Lehre definiert.

Dazu soll im Besonderen erfasst werden, welche Ansprüche speziell das Studium der Veterinärmedizin in dieser Phase stellt. Zum anderen werden die bereits bestehenden Angebote untersucht, die das selbstregulierte Lernen der Studierenden fördern. Zusätzlich wird in dieser Arbeit weiterer Bedarf der Studierenden bezüglich der institutionellen Hilfestellung insbesondere in diesem Studienabschnitt ermittelt.
