Abstract
Neurological disease attributed to migration of the rat lungworm (Angiostrongylus cantonensis), is described in three captive rufous bettongs (Aepyprymnus rufescens). Clinical signs, including ascending paralysis and multifocal neurological deficits, were similar to those seen in other species. Histologically, the severity of meningoencephalomyelitis ranged from mild to moderate. In one animal cerebrospinal fluid contained a high percentage of eosinophils but peripheral blood cell counts were within normal limits. Treatment with dexamethasone, diazepam and vitamin E was unsuccessful. The prognosis for bettongs with this disease is poor. The susceptibility of this species to this disease has implications for enclosure design.
