| Reference | Dogs in study | Type of RT-PCR | Small intestine | Colon | Histology done? |
| 15 | 12 disease-free 4 IBD 2 nonresponders 10 small intestine bacterial overgrowth | Semiquantitative | X | Yes | |
| 44 | 6 disease-free 14 IBD 6 nonIBD diarrheic | Semiquantitative | X | Yes | |
| 41 | 18 disease free 39 chronic enteropathy | Real-time | X | Yes | |

Objective grading criteria were used during histology to characterize mucosal inflammation.
