hemorrhagic enteritis is an acute digestive disorder affecting young turkeys. marble spleen disease is an acute respiratory disease of pheasants. both diseases are caused by similar viruses. infection typically occurs when birds ingest the virus, which is often introduced to a flock through contaminated clothing or equipment.
clinical signs
turkey poults and pheasants less than four weeks of age are typically resistant to infection due to the presence of maternal antibodies.
