The adherent-invasive Escherichia coli (AIEC) pathotype could play a role in the course of Crohn’s disease. This is characterized by its capacity to adhere to and to invade intestinal epithelial cells as well as to replicate and survive within macrophages. At present, identification of the AIEC pathotype relies on time-consuming techniques based on the phenotypic screening of cultured bacteria, which are not standardized. In this thesis, we focused on the study of AIEC genetics in order to look for key characteristics that could assist the development of a molecular tool for the identification of the pathotype.
To sum up, the results of this work provide meaningful information that contributes to our understanding of AIEC genomics. In this case, two putative molecular markers resulting from a combination of genetic and/or phenotypic features have been presented and these could assist in AIEC screening. Finally, gene expression results provide new insights to better describe genes putatively involved in AIEC virulence
