An unusual tracheal foreign body in a cat and the problems associated with its removal is described. A review of other documented feline tracheal foreign bodies is included.
A case of encephalomyelitis and polyradiculoneuritis caused by the protozoan parasite Neospora caninum is described in a 17‐week‐old bloodhound puppy exhibiting progressive paraplegia, Exposure of the dam and litter to N caninum was confirmed by serological testing for specific antibodies. A successful treatment regimen was employed in a littermate, and in two puppies from a subsequent litter from the same dam, all showing ataxia and hindlimb proprioceptive deficits.
An assay for the measurement of von Willebrand factor antigen has been established. In a period of 18 months, 13 dogs have been identified as suffering from von Willebrand's disease. The affected animals had levels of von Willebrand factor antigen which ranged from undetectable to 43 per cent of normal. Factor VIII levels were also reduced. Haemorrhagic episodes were usually associated with trauma or surgery, and often required transfusion with fresh blood or plasma to arrest haemorrhage.
I ABSTRACTA polyradiculoneuritis and polymyositis caused by a toxoplasma-like protozoan is described in two seven-week-old labrador pups. Examination of a centrifuged sample of cerebrospinal fluid was a useful diagnostic aid in one case and the successful treatment of the other pup is described. This case is discussed in the light of the recently described protozoan Neospom caninum which can also affect the neuromuscular system of neonatal pups.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
