  Bornavirus
BDV is a noncytolytic, neurotropic RNA virus and the causative agent of Borna disease, a severe (frequently fatal) neurological disease of horses and sheep, characterised by progressive, nonpurulent encephalomyelitis.
In 1926 the cause of Borna disease was identified as Borna disease virus (BDV).
The symptoms of Borna disease in horses and sheep include behavioural changes, hyperactivity and disturbances in gait during the early stages of infection, with ataxia and partial paralysis being observed during the terminal stages of the disease.

The viral antigen and nucleic acid of BDV persists in the brain tissue of cats causing chronic inflammatory lesions.

For example, antibodies to the virus have been found with higher frequency in the blood of people with diseases such as panic disorder than in controls.
Scientists only suspect that the virus is transmitted through the nasal passage, and it is not clear whether the virus passes from animals to humans or if there is a specific human strain.
Also, the disease occurs only sporadically in a small endemic region in central Europe, which suggests there is an animal reservoir, such as a rodent, but so far none has been identified.

In animals, BDV clinical manifestations range from inapparent infections, behavioral abnormalities (including depression, circular movement, standing in awkward positions, collapsing, and running into obstacles) obesity, fertility problems, and neurological diseases such as paralysis.
Studies have indicated that cases of inapparent BDV infection may be common in humans as well.

Borna disease is actually caused by side effects of the immune response to the viral infection, not by the virus itself.
BDV can infect a wide range of warm-blooded animals with horses and sheep being the main natural hosts; there is speculation that BDV can also infect humans.
Technical Abstract: The maturation of Borna disease virus (BDV) glycoprotein GP was studied in regard to intracellular compartmentalization, compartmentalization signal-domains, proteolytic processing, and packaging into virus particles.

Although a genetic component is likely, discordance for disease in monozygotic twin studies and epidemiology suggest the presence of cofactors.
BDV is a neurotropic RNA virus, worldwide in distribution, that causes movement and behavior disturbances in warmblooded animal hosts ranging from birds to primates.
Thus, the significance of BDV for pathogenesis of neuropsychiatric disease remains controversial.
