Tick-borne encephalitis virus in dogs - is this an issue?
Parasites & Vectors 2011, 4:59 (13 April 2011)
Tick-borne encephalitis (TBE) is geographically spreading and emerging in many regions in Eurasia. Dogs are accidental hosts not capable of further spreading TBE virus but they readily seroconvert upon infection. Clinical disease used to be a rare finding but the number such reports is increasing. This warrants an update on the epidemiology, clinical presentation and possible prevention of TBE in the dog. Image: Transmission of TBE virus to a dog via the bite of an Ixodes tick.
