Border disease virus X818 An isolate of

Border disease virus.

Borna disease virus (BDV) The only species in the genus Bornavirus. Named after a town in Saxony where the first major outbreak in horses occurred. Negativestrand RNA virus which produces persistent infection in a variety of experimental animals. Virions are enveloped with spherical morphology 90 nm in diameter and contain a genome of single-stranded RNA, 8.9kb in length. Replication involves the cell nucleus. Horses and sheep appear to be the main natural hosts. Causes lassitude, followed by excitation with tonic spasms and later paralysis in horses. A similar disease is produced in sheep, cattle and probably deer. Experimental infection of rabbits produces a similar disease. Sporadic cases of natural infection have been reported in donkeys, mules and llamas. Guinea pigs, rats and mice can be infected experimentally. Human infection has been suggested by the reported detection of virus-related sequences in peripheral blood leukocytes of some patients with psychiatric disorders. These results require confirmation. The disease in horses has been detected mainly in Saxony but also in other parts of Germany, the Principality of Liechtenstein, Poland, Rumania, Russia, Syria and Egypt. A virus causing staggers in horses in Nigeria may be the same. The virus has been isolated from ticks of several genera and from the brains of herons and other wild birds. Transmission by oral and nasal secretions is possible. A virus vaccine has been used with success. Replicates on the CAM and in cultures of lamb testis and monkey kidney cells with CPE.
