| experimentally induced cerebrospinal nematodiasis in rabbits (oryctolagus cuniculus). | to determine if the rabbit can act as an intermediate host for ascarids from certain carnivorous animals (skunks, pigs, dogs), 12 rabbits were infected with ascaris columnaris, ascaris suum, or toxocara canis. clinical signs, microscopic lesions, and morphologic features of ascarids with naturally occurring and experimentally induced a columnaris infections were identical. of the 3 induced parasitic infections, a columnaris caused the most severe lesions in the central nervous system (cns). it a ... | 1975 | 1115433 |
| an epizootic of cerebral nematodiasis in rabbits due to ascaris columnarus. | an epizootic of cerebral nematodiasis due to ascaris columnaris occurred in a commercial rabbitry, and 80 diseased rabbits died or were killed. the morbidity was high in groups of recently purchased rabbits and in the offspring of 12 breeder rabbits. the breeder rabbits which had been on the farm for more than a yr survived the outbreaks. wild animals and birds had access to the facilities, but raccoons and skunks were never observed. a columnaris larvae were found on histopathologic examination ... | 1975 | 1121166 |
| an epizootic of cerebrospinal nematodiasis in cottontail rabbits. | a progressively debilitating neurologic syndrome characterized by torticollis, ataxia, circling, and abnormal posture was observed in 16 of approximately 60 cottontail rabbits (sylvilagus floridanus) captured in a 12-hectare portion of a woodlot in southwestern virginia. inflammatory and degenerative alterations in cerebellum and midbrain regions were characterized principally by malacia, perivascular cuffing, and gliosis. single ascaris columnaris larvae were found in the cerebellum of 2 rabbit ... | 1975 | 1176355 |
