| Total Gram negative | Total Gram positive | E coli | Klebsiella spp | Proteus spp | Streptococcus spp | Enterococcus spp | Staphylococcus spp | |
|---|---|---|---|---|---|---|---|---|
| n (%) | n (%) | n (%) | n % | n (%) | n (%) | n (%) | n (%) | |
| CD, Crohn’s disease; IC, indeterminate colitis; LNH, lymphonodular hyperplasia; n, number of bacterial isolates; UC, ulcerative colitis; %, percentage of strains isolated in ileum mucosa biopsy specimens calculated as number of isolates found with respect to total Gram-negative or Gram-positive isolates detected in each group. | ||||||||
