摘要
Borna disease virus (BDV) is a neurotropic agent with capacity to infect and cause encephalomyelitis in a wide range of animals, including horses, sheep, cattle and cats. Recent interest in BDV as a potential human pathogen has been stimulated by reports of BDV-specific antibodies and nucleic acid in patients with neuropsychiatric diseases. The pathogenesis of Borna disease (BD) in naturally infected animals is believed to be immune-mediated, mainly through the action of cytotoxic T cells. In this paper, a case of feline ED with atypical clinical and histopathological features is reported. Clinically, the cat showed muscle fasciculation and proprioceptive defects. Despite absence of encephalitis, numerous neurons were infected with BDV as shown by in-situ hybridization. This indicates that BDV infection may lead to various disease patterns, depending on differences in viral pathogenicity, or on as yet unidentified host-specific factors.
