Epidemiology of ST131 in Besançon University Hospital
Epidemiology of ST131 in Besançon University Hospital
The sequence type 131 (ST131) is a predominant lineage among extraintestinal pathogenic
 Escherichia coli. It plays a major role in the worldwide dissemination of E. coli that
 produce extended-spectrum beta-lactamase (ESBL). The aim of this study was to describe the
 epidemiology of ESBL producing ST131clonal group in our university hospital. All patients
 with an infection due to ESBL E. coli will be prospectively included for a 2-year period.
 ST131 isolates will be identified and risk factors associated to ST131 will be determined in
 comparison to non-ST131 ESBL E. coli.
Inclusion Criteria:

 -  Patients infected with ESBL producing E. coli

 Exclusion Criteria:

 -  Patients known to be carrier or infected in the previous year, patients only colonised
 with ESBL producing E. coli.
