Here you will find information about Research groups in the PathoGenoMics fields from the ERA-NET partner countries (Austria, Finland, France, Hungary, Israel, Latvia, Portugal, Slovenia and Spain).
This information is supposed to support cooperation between researchers from different European countries
and thus enhance the development of a European Research Area for PathoGenoMics .


The following information is available and can be searched for:

  • researcher names
  • Institution of the respective researcher, city and country of his/her institution
  • Contact data of the researcher (address, phone, email)
  • Research topics and studied microorganisms of the researcher
  • Special techniques applied by the researcher
  • Potential cooperation topics suggested by the researcher

Research Topics:
Food safety, is a public health priority. Bacterial contamination during food processing can be limited by the use of processes (sterile room…) which are currently developed by the food industry. Raw food is thus among the main sources of bacterial contamination in the food chain. In this context, the research team focuses on bacteria that contaminate food raw materials from animal origin and that can be transmitted to humans. Among pathogenic bacteria, priority is given to Listeria, and Salmonella. Both bacteria are facultatively intracellular and their main route of entry into the body is through the digestive tract. Asymptomatic animal carriers, i.e. animals harbouring potentially pathogenic bacteria without developing clinical signs, are the main source of contamination by Salmonella and Listeria. The mechanisms at the origin of the persistence of bacteria within a host remain poorly understood. The main aim of our team is to understand the mechanisms of virulence and persistence looking at both pathogen and host sides. Concerning Listeria we especially focuse on the low virulence L. monocytogenes strains


Organisms studied:
  • Listeria spec.
  • Salmonellae


Special methods / technologies:
microarrays (Salmonella and poultry) cell culture models (quantitative method to assess the low virulence of Listeria monocytogenes strains) Experimental infection models of sheep and chicken


Suggestions for potential research cooperations:
I know insufficiently the scientific aims of ERA net.we are interested by the works on the interaction of bacteria with intestinal cells
