Comparison between indirect fluorescent antibody (IFA), direct immunohistochemistry (D-IHC), and reverse transcription-PCR (RT-PCR) results to detect turkey coronavirus from field samples (n = 100) obtained from commercial turkey poults presenting acute enteritis
| Samples | IFA | D-IHC | RT-PCR |
|---|---|---|---|
| Ileum | ++ (55/100) | ++ (58/100)1 | 60/1002 |
| Ileum-cecal junction | ++++ (100/100) | ++++ (100/100) | 100/100 |
| Ceca | ++++ (100/100) | ++++ (100/100) | 100/100 |
