Gross lesions will be similar to those found in canines. Animals will suffer photophobia (excessive sensitivity to light). Gross lesions will include oculonasal discharge, hyperkaratosis of the planum nasale and footpads, papular rashs around chin and bronchopneumonia. Microscopic lesions will include brightly eosinophilic intracytoplasmic and intranuclear inclusions often in epithelial cells, neurons, WBCs and megakaryocytes. (Studies have shown that the biliary epithelium, urinary bladder and renal pelvis are the most productive places to look for these inclusions. A non-suppurative encephalitis with de-mylination may also be seen.
