Borna disease virus (BDV) is a neurotropic virus with a broad host
and geographic range. Lewis rats were immunized against BDV with a
recombinant vaccinia virus expressing the BDV nucleoprotein and were
later infected with BDV to evaluate protection against Borna disease
(BD). Relative to animals that were not immunized, immunized
animals had a decreased viral burden after challenge with infectious
virus, more marked inflammation, and aggravated clinical disease. These
data suggest that a more robust immune response in Borna disease can
reduce viral load at the expense of increased morbidity.
