Experimentally transmitted marble spleen disease in pen-raised wild turkeys.

Pen-raised North American wild turkeys (Meleagris gallopavo L.) were experimentally infected with marble spleen disease (MSD) to determine their susceptibility to this disease. Gross and microscopic lesions were consistent with experimental MSD in pheasants and domestic turkeys: an enlarged mottled spleen, intranuclear inclusion bodies, and absence of pulmonary edema and hemorrhage. Detectable levels of viral antigen were not demonstrable in sera of turkeys using the agar gell precipitin test.
