The development of multi-resistant bacteria is a key concern in medicine as individual patients cannot longer be treated successfully (“post antibiotic era”). The Extended-ß-lactamase (ESBL) producing E. coli of Sequence type 131 (ST131) is of particular concern as it is a virulent extraintestinal pathogenic E. coli (ExPEC) that has spread pandemically. The reason for this success is unclear, but it is discussed that a combination of virulence, multi-resistance and a particular genomic backbone confers this potential due to the ability of a genetic link between biofilm production and resistance. Starting with a total of 71 ST131 strains from humans, the environment and several animal hosts from two continents (Europe and Asia) which will be extended by our current and future clinical studies we will perform WGS and phenotypical assays for bacterial fitness to challenge our hypothesis. Furthermore we will unravel the microevolution of this highly virulent pandemic ST131.
