Comparison between indirect fluorescent antibody (IFA), direct immunohistochemistry (D-IHC), and reverse transcription-PCR (RT-PCR) results to detect turkey coronavirus from intestine sections (n = 50) obtained from experimental-infected turkey embryos
| Samples | IFA | D-IHC | RT-PCR |
|---|---|---|---|
| Ileum | ++ (43/50) | ++ (45/50)1 | 40/502 |
| Ileum-cecal junction | ++++ (50/50) | ++++ (50/50) | 50/50 |
| Ceca | ++++ (50/50) | ++++ (50/50) | 50/50 |

The intensity of dark red deposit was arbitrarily rated on a scale of − (undetectable) to ++++ (the pattern present at its highest intensity).
