Causes: Unclassified virus (possibly a reovirus). Spread by faecal-oral route.

Effects: Incubation period is 1-7 days. Depression, sudden death, morbidity to 100% and mortality to 50% can occur. Dehydration, diarrhoea and stunting are common signs.

Young turkeys are susceptible to this acute and highly contagious disease. This is an unclassified virus (possibly a reovirus).

Spread of faecal-oral route.

Birds are severely immunosuppressed.

(There is a 1-7 day incubation period). Depression, sudden death and morbidity at 100% and mortality to 50% can occur. Dehydration, diarrhoea and stunting.

Lesions include enteritis and peritonitis.

Clinical signs and gross lesions in the intestine of young turkeys are characteristic. Isolation of the virus from the liver in the yolk sac of embryonating eggs is helpful and reinoculate day-old poults to reproduce the disease.

Biosecurity is important and depopulate infected flocks for two consecutive growing cycles.

None.
