Meningoencephalitis in a Boelen's python (Morelia boeleni) associated with paramyxovirus infection.
An adult male Boelen's python, Morelia boeleni, presented with acute neurologic disease and was euthanatized. Histologic examination revealed nonsuppurative meningoencephalitis. Occasional eosinophilic intracytoplasmic inclusions were noted in glial cells. On the basis of clinical signs and histopathology, inclusion body disease of boid snakes was suspected, but inclusions were not seen in other organs commonly affected with the disease. Moreover, electron microscopy revealed that the inclusions contained stacks of filaments 13-14 nm wide. With the use of a generic paramyxovirus cDNA probe, sections of brain and esophageal ganglion demonstrated hybridization. The findings indicate that paramyxovirus was the likely cause of the encephalomyelitis in this python, and this virus should be included in the differential diagnosis of pythons exhibiting central nervous system disease.
