Comparative investigation of functional heart parameters by means of magnetic resonance imaging, computed tomography and echocardiagraphy
Vergleichende Untersuchung funktioneller Herzparameter beim Hund mittels Magnetresonanztomographie, Computertomographie und Echokardiographie
Project Investigators: Stephan Hungerbühler; Anne Sieslack; Judith Meyer; Patrick Wefstaedt, Peter Dziallas, Davina Wolf; Ingo Nolte
Duration: Beginning 2011 until 2014
Project Details:
Goldstandard für die exakte Ermittlung kardialer Funktionsparameter ist in der Humanmedizin die Magnetresonanztomopgraphie. In der Veterinärmedizin beim Hund fehlen bisher vergleichende Erkenntnisse zur Wertigkeit der Untersuchungsverfahren CT, MRT und Echokardiographie für die kardiale Funktionsdiagnostik. Neben der Durchführung dieses Vergleiches ist ein weiteres Ziel dieses Forschungsprojektes auch den Einfluß der im Rahmen der Durchführung kardialer Funktionsprüfungen mittels MRT und CT erforderlichen Narkose im Vergleich zur Echokardiographie mit und ohne Narkose zu untersuchen.

Collaborative Research in Rural and Commercial farming of Chile
Collaborative Research in Rural and Commercial farming of Chile
Project Investigators: Prof. Dr. L. Kreienbrock
Duration: 2011 until 2014
Project Details:
We are preparing projects in close collaboration with the University of Chile, San-tiago, the Agricultural and Fisheries Services, Chile in the area of animal health and food production.
Chile is composed of a large variety of aboriginal ethnic groups that have lived in its territory for thousands of years. Although initially only the groups in the north domesticated animals (Llamas & Guanacos), nowadays all of them practice animal husbandry at some level. In 2007 a full scale agricultural census took place in Chile, generating valuable information regarding both key elements: ethnic group of the owners and number of animals of each species simultaneously. Additional other information of agricultural interest was also integrated into the census data. This study therefore focuses on this association and describes the relationship of different Chilean ethnic groups and their animals especially with their non-aboriginal counterparts for the first time.
The analyses are conducted in a multi-step stratified approach using administrative regions as well as geographical measures (altitude, agricultural zone etc) as classes to adjust for possible confounding and to study interactions in the different live-stock systems.
The results of this study can be of great interest to develop a new series of studies exploring the animal husbandry traditions of Chilean aboriginal ethnic groups, and by doing so, helping the government to develop their agricultural policies according to each specific group.

Project Details:
BioBricks? sind austauschbare, standardisierte DNA-Bausteine, die vom MIT entwickelt wurden. Hierbei handelt es sich um DNA-Sequenzen, die für bestimmte zelluläre Funktionen kodieren und so als genetische Bausteine fungieren. Solche Funktionen können z.B. die Synthese eines Proteins (kodierende Gensequenz) oder die Regulation von Genen sein (Promotor). Sie sind frei miteinander kombinierbar und können in eine Zielzelle eingebracht werden. Ein zentraler Vorteil dieser Technologie ist, dass bereits eine umfangreiche Sammlung von BioBricks? existiert, auf die man unter http://Parts-Registry.org zugreifen kann. Diese lassen sich mit Hilfe einer standardisierten Klonierungstechnik frei miteinander zu genetischen Systemen kombinieren, die dann eine bestimmte komplexere biologische Funktion erfüllen.
Sie bieten ein hohes Maß an Flexibilität. Ein mittels BioBrick?-Technologie entwickelter Prototyp-Salmonellenindikatorstamm könnte zum Beispiel individuell hinsichtlich seines Ausgabesignals mit relativ geringem Aufwand verändert werden. Umgekehrt kann bei einem Indikatorstamm mit einem gut funktionierenden Ausgabesignal das Salmonellen erkennende BioBrick? gegen ein BioBrick? ausgetauscht werden, welches beispielsweise für einen Rezeptor kodiert, der andere Krankheitserreger spezifisch erkennen kann. Das von uns entwickelte Produkt würde somit vielfältige Perspektiven für einen wachsenden Markt bieten.

Development of the e-learning course "Food-borne zoonoses associated with pork meat and pork meat products"
Erstellung eines Casus E-Learning Moduls zum Thema "Lebensmittelassoziierte Zoonosen beim Schwein"
Project Investigators: Dr. N. Sudhaus; Prof. G. Klein
Duration: 2011 until 2014
Funding: Gesellschaft der Freunde der Tierärztlichen Hochschule Hannover (GdF), 5.000 EUR
Project Details:
Wie die WHO bereits feststellte ist "die menschliche Gesundheit unauflöslich verknüpft mit der Tiergesundheit und Tierhaltung." So sind laut WHO 75% aller neuen Erkrankungen beim Menschen Zoonosen. Zur Kontrolle der lebensmittelassoziierten Zoonosen müssen insbesondere die Tierärztinnen und Tierärzte, die im Bereich der Schlachttier- und Fleischuntersuchung tätig sind, geschult werden. Daher ist es von enormer Wichtigkeit, diesen Tierärzten eine Fortbildungsmöglichkeit zu schaffen, die sie zeitlich und örtlich unabhängig absolvieren können. Hierzu soll das Modul "Lebensmittelasoziierte Zoonosen beim Schwein" einen wichtigen Beitrag leisten.

Diagnosis of goats shedding Mycobacterium avium spp. paratuberculosis after vaccination with Gudair® by PCR in faecal, milk and colostrum samples
Diagnostik der Paratuberkulose bei Ziegen, nach Impfung mit Gudair(R) mittels PCR in Kot-, Milch- und Kolostrum-Proben
Project Investigators: Prof. Dr. M. Ganter; Sarinya Rerkusuke
Duration: September 2010 until December 2014
Funding: Ohne Drittmittelfinanzierung. Kosten im Untersuchungsbetrieb wurden durch die Tierseuchenkasse NRW abgedeckt.
Project Details:
Recent serological investigations in over 150 sheep and goat flocks showed that Johne?s disease is prevalent in over 2/3 of all flocks. In a dairy goat flock we found the highest intra flock prevalence of 19%. For sanitation of the flock lambs are reared motherless, seropositive goats will be slaughtered and all goats and the replacements will be vaccinated with Gudair®. Numerous investigations show that vaccination with Gudair® reduces the clinical symptoms of Mycobacterium avium spp. paratuberculosis (MAP) infections, and the shedding of MAP. After vaccination differentiation between infected and non infected animals is not feasible by serological investigations. Therefore detection of MAP in faeces and milk is performed. Preliminary investigations show that intersection between seropositive animals before vaccination and animals shedding MAP by faeces or milk is relatively low. Therefore the PCR methods have to be optimized to detect infected and shedding animals.

Acoustic communication in nonhuman primates (ACIP). Loud calls of Proboscis monkeys - a suitable tool for conservation?
Akustische Kommunikation bei nicht-menschlichen Primaten: Fernkontaktrufe bei Nasenaffen - ein geeignetes Werkzeug für den angewandten Arten- und Naturschutz?
Project Investigators: Prof. Dr. Elke Zimmermann
Duration: 2010 until 2014
Funding: DAAD
Project Details:
Comparative bioacoustic studies in nonhuman primates have shown that loud calls may provide important non-invasive tools for identifying and monitoring species, for assessing their abundance and for the reconstruction of their phylogeny. Proboscis monkeys represent a strictly folivorous primate taxon, endemic to Borneo. They were assigned to the category endangered by the IUCN Redlist 2010 with an estimated population size of a few thousand animals in the remaining patchy forests in Sarawak and Sabah in Malaysian Borneo and in Kalimantan in Indonesian Borneo. The major cause for the species decline is anthropogenically caused habitat destruction. Proboscis monkeys are very difficult to monitor in the wild, as they are arboreal and prefer dense foliage in riparian-riverine forests swamp forests and mangroves. The longer-term goal of the project is therefore to develop a new censusing method for these animals based on presenting species-typical loud calls in order to elicit antiphonal calling from resident males. The immediate aim of this project is to describe the acoustic structure of male loud calls in two geographically isolated proboscis monkey populations in Borneo and to explore to which degree subspecies and individual differences are reflected in those acoustics. In addition, video recordings and analysis will be made of vocalizing males in order to test the hypothesis that males producing loud calls inflate their unusually large noses to produce additional vocal resonance. Furthermore video-recordings and analysis will be made on the behaviour of the Proboscis monkey group to playback of loud calls to assess call function.
