Rhinitis and disseminated disease in a ferret (Mustela putorius furo) naturally infected with Sarcocystis neurona.
Naturally occurring Sarcocystis neurona infection in a ferret (Mustela putorius furo) with rhinitis and disseminated disease are described for the first time. The ferret exhibited severe rhinitis with intra-lesional S. neurona merozoites and schizonts. Diagnosis was confirmed immunohistochemically by staining with S. neurona-specific antibodies, and by phylogenetic analyses of conserved and variable portions of nuclear ribosomal DNA. On the basis of intense schizogony in the nasal mucosa, we propose the possibility of an olfactory nerve pathway route of infection for S. neurona meningoencephalitis.
