Abstract

Neural angiostrongyliasis and neosporosis are the two most common infectious causes of spinal cord disease in young dogs. The former is caused by migration of Angiostrongylus cantonensis (rat lungworm) larvae following ingestion of mollusc intermediate hosts, while the latter is caused by the apicomplexan protozoan Neospora caninum, acquired transplacentally, during parturition or in the neonatal period. This article gives the reader the perspective of a veterinarian confronted with the diagnosis and treatment of these two potentially life-threatening infections, taking into account differences in epidemiology and pathogenesis, and listing diagnostic tests available and affordable for most owners. The broader implications of these infections for other species, including people and wildlife, are discussed.
