  • 2-a ER, early recurrent ileal lesion;

  • 2-b CIL, chronic ileal lesion;

  • 2-c CDH, healthy ileal mucosa from CD patients without recurrent lesion;

  • 2-d controls, biopsy specimens from patients with non-inflammatory bowel disease and stools from healthy non-hospitalised individuals;

  • 2-e one patient was considered twice because he presented early endoscopic recurrence at two and three years after surgery;

  • 2-f some patients harboured more than oneE coli isolate distributed in several groups;

  • 2-g another patient was also considered twice because he was operated on for CD (chronic lesion) and presented early endoscopic recurrence after surgery.
