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

Name: Dr. Nassif, Xavier

Research Topics:
Extra-cellular bacterial pathogens are the main cause of infections in developed countries and are often responsible for nosocomial infections. Paradoxically these bacteria are mostly commensal, and become invasive only in certain circumstances linked to the host. Among the great variety of commensal bacteria that colonize a human only a small fraction of these are responsible for systemic infections. Furthermore, it should be pointed out that some of these, once septicemic, have the ability to cross the blood brain barrier. Our goal is (i) the identification of the mechanisms by which a bacteria can stop being a commensal and disseminate from its normal niche ; and (ii) once it is septicemic how it can cross the blood brain barrier. To achieve these goals we intend to use two different bacterial pathogens, Neisseria meningtidis and Escherichia coli.


Organisms studied:
  • Escherichia coli
  • Neisseria meningitidis


Special methods / technologies:
We use microarrays
