Naturally occurring cerebrospinal parelaphostronglylosis

An isolated case and an outbreak of parelaphostrongylosis in goats are described. Signs included tetraparesis, hemiparesis, tetraplegia, spastic gait, scoliosis, vestibular strabismus, blindness, and death. Five cases were necropsied and nematodes were seen in the brain and spinal cord of four of these. Intact adult nematodes from two cases were identified as Parelaphostrongylus tenuis, the meningeal worm of white-tailed deer. Cerebrospinal fluid analysis from affected goats showed a moderately elevated protein content, evidence of hemorrhage, and mononuclear cell and eosinophil pleocytosis. Recoveries are recorded.
