Polimiosite por Neospora caninum em um filhote de golden retriever – relato de caso

Abstract

Neosporosis is a disease caused by the protozoan Neospora caninum that can lead to neurological signs and death in dogs. There are not many reports of this disease in Brazil. The aim of this paper is to describe a case of neosporosis in a young male golden retriever that presented limited mobility, pain and spasticity of the hind limbs. Result of serodiagnosis (IIF-IgG) was positive for Neospora (titer of 6400). The presence of clinical signs associated with high serology titers allowed the presumptive diagnosis of neosporosis. Antimicrobial therapy with trimethoprim sulfamethoxazole and pyrimethamine was instated for 120 days. The animal was monitored during this period and also underwent to physiotherapy sessions. There was partial improvement, although muscle contracture remained. This disease should be considered an important differential diagnosis in young dogs with extension stiffness and contracture of the hind limbs.
