Molecular characterization of human reservoirs potentially pathogenic Escherichia coli, animal and environmental

Characterization of potentially pathogenic E. coli samples from different origins.


  • Detection of virulence genes using quantitative real time PCR to distinguish the samples intended for isolation of a positive strain.
  • Studies of antibiotic resistance in strains from healthy animals.
  • Assess the genetic diversity of STEC isolates by pulsed field gel electrophoresis (PFGE) and Next Generation Sequencing (NGS).
  • Detection serogroups / serotypes related-genes associated with hemolytic uremic syndrome (HUS).
  • Shigatoxin producing E. coli prevalence studies in healthy animals.
