TBEV is a member of the genus Flavivirus. It is the virus associated with tick-borne encephalitis. TBEV has three subtypes: Western European subtype, Siberian subtype and Far Eastern subtype.
Tick-borne encephalitis (TBE) is a viral infectious disease involving the central nervous system. The disease most often manifests as meningitis, encephalitis, or meningoencephalitis. Long-lasting or permanent neuropsychiatric consequences are observed in 10 to 20% of infected patients.
In dogs, the disease also manifests as a neurological disorder with signs varying from tremors to seizures and death.
In ruminants, neurological disease is also present, and animals may refuse to eat, appear lethargic, and also develop respiratory signs.
