| Abstract | ||||
| The course of turkey coronavirus (TCoV) infection in young turkey poults was examined using a field isolate (TCoV-MG10) from a diarrheal disease outbreak on a commercial turkey farm. One day old and 25-day-old poults were inoculated orally with TCoV-MG10 to examine the effect of age on viral shedding. The presence of coronavirus particles measuring 105.8±21.8 nm in the cloacal contents was confirmed using transmission electron microscopy. The pattern of cloacal TCoV shedding was examined by RT PCR amplification of the nucleocapsid (N) gene fragment. Poults were found equally susceptible to TCoV infection at day of age and at 3 weeks of age and turkeys of either age shed virus in their feces starting as early as 1 day postinoculation up to 17 days post-inoculation. Infected birds had profound villus atrophy with some compensatory crypt hyperplasia at 5 to 7 days post infection (7 dpi). | ||||
