Molecular genetic analysis of epidermolysis bullosa in the sheep
Molekulargenetische Aufklärung der Epidermolysis bullosa beim Schaf
Project Investigators: Prof. Dr. O. Distl; Prof. Dr. M. Ganter; Prof. Dr. M. Hewicker-Trautwein; Dr. S. Mömke

Funding: Schafzuchtverbände, 5.000 EUR
Project Details:
Die Epidermolysis bullosa ist eine kongenitale Anomalie beim Schaf, die bei einigen Rassen weit verbreitet ist. Deshalb soll für diese kongenitale und letale Anomalie die kausale Mutation aufgedeckt werden und der Zuchtpraxis ein Gentest zur Verfügung gestellt werden. Die bisherigen Arbeiten beim Schwarzköpfigen Fleischschaf zeigten, dass die Epidermolysis bullosa monogen autosomal rezessiv vererbt wird. Die potenziellen Kandidatengene werden jetzt auf kausale Mutationen untersucht.

Kongenitale Anomalien sind beim Schaf weitverbreitet. Viele dieser Anomalien sind erblich bedingt. Deshalb sollen mittels klinischer, pathologisch-morphologischer, zytogenetischer und molekulargenetischer Methoden die erbliche Genese aufgeklärt werden. Die Fälle werden von Tierärzten, Schafhaltern und Schafgesundheitsdiensten gemeldet. Weiterhin soll das Meldesystem verbessert werden. In Einzelfällen werden Zuchtversuche durchgeführt.

Control of the intestinal flora ecology in poultry for ensuring the products safety for human consumers
Kontrolle der Instestinalflora beim Geflügel zur Sicherstellung des gesundheitlichen Verbraucherschutzes
Project Investigators: Prof. Dr. G. Klein; Dr. V. Atanassova; Dr. Al-Masri; F. Reich; M. Langen
Duration: April 2005 until March 2008
Funding: EU-Kommission, FP 6 Projekt: POULTRYFLORGUT
Project Details:
European consumers are becoming increasingly concerned over the safety and nutritional quality of their food, which must be free from chemical and biological contaminants. At the same time, food production systems must meet the concerns of consumers for animal welfare, the environment and public health. This leads to, for instance, rapid changes in both poultry nutrition (e.g. abandoning of the use of infeed antibiotics regulating the intestinal microflora, banning of meat-meal and animal fat products from animal feed, and use of the 100%-vegetal diets) and rearing (e.g. reduction of the number of available anticoccidial substances, development of outdoor breeding and organic farming) context. These drastic changes raised questions in the scientific community and the Agro-Food industry concerning an increasing risk of microbiologic contamination of poultry products (meat, eggs), and therefore demands a thorough and comprehensive investigation of all parts of the poultry industry.
The over-all objective of the project is to provide a strong factual basis for the optimisation of the hygienic quality of the poultry products meant for human consumption, in conformation with the new European regulations concerning feed additives, and the changes occurring in poultry production in response to public concerns in terms of animal welfare, the environment and health. A special focus is given on the control of the intestinal flora of the broilers and laying hens, including the food-borne pathogens. The approach to reduce microbial risks associated with consumption of poultry products (eggs, meat) concerns the different steps of poultry products production from the farm to marketing. It concerns perfection of housing systems, poultry flocks management and feeding, slaughterhouse processing, and it can be applied whatever the poultry production system, in particular to new poultry housing systems (in-doors, out-doors, new cages?) independent of the size of the flock. Looking at the consequences of the new poultry production system and management on poultry products safety should provide supplementary information to adapt, if needed, the new EU regulations concerning feed additives but also foodborne pathogens control. Improving the safety of poultry products will contribute for satisfying European consumer demand for better and safer food products. The subobjective of the project is to develop methodologies, using mainly novel molecular techniques, allowing the global and integrative study of the intestinal flora of the poultry. These methodologies will make it possible to define and validate intestinal health or pathological microbiological criteria in poultry.
Strategic objectives addressed This project has two main goals. The first goal is to determine to what extend the bacteriological safety of poultry products (meat, eggs) is affected by the new European regulations concerning feed additives, and by the changes occurring in poultry production in response to public concerns in terms of animal welfare, environment, and health. The second goal is to find solutions to monitor and control the intestinal flora ecology in poultry and on poultry products in order to reduce the food-borne pathogens prevalence and to improve the safety of the poultry products for consumers.
The strategic objectives of this proposal can be summarized as follows:
1-Associate the occurrence of food-borne pathogens in poultry farms, in different European countries, with different production systems (in-doors, out-doors?) and to determine how to improve management in order to decrease the prevalence of food-borne pathogens.
2-Quantify the food-borne pathogens at the different steps of processing in slaughterhouses in different European countries and to determine possible improvements.
3-Create an European molecular data-base on traditional and (re)emerging foodborne pathogenic strains/species in European poultry production.
4-Improve the characterisation of the digestive troubles occurring in the field since the banning of the in-feed antibiotics and specification of their prevalence, of the incidence and of some causal factors.
5-Assess novel techniques allowing the study of the intestinal flora and of the relation-ship between the whole flora and the food-borne pathogens in poultry.
6-Create a European database on intestinal flora profiles of the animals in European poultry production.
7-Estimate the socio-economic consequences of the changes occurring in poultry production in response to the new European regulations and to the (public) European citizens concerns.
The workplan has a total duration of 36 months. 15 partners representing 11 member states inclunding two new member states are working within the project.
The Institute for Food Quality and Food Safety is involved in objectives 1-3 and is a work-package co-ordinator.
