Naturally occurring neurologic disease in a fallow deer infected with meningeal worms.

Neurologic disease resulting from infection with Parelaphostrongylus tenuis was diagnosed in a fallow deer (Dama dama) from Georgia, with clinical signs and histopathologic lesions similar to those reported for other accidental hosts of P. tenuis. Early fifth stage parasites were found in the spinal meninges and immature parasites were found in the neural parenchyma, but none were recovered from the brain and cranial meninges.
