Tick-borne Encephalitis Virus in Wild Rodents in Winter, Finland, 2008–2009
نویسندگان
چکیده
Rodents might maintain tick-borne encephalitis virus (TBEV) in nature through latent persistent infections. During 2 subsequent winters, 2008 and 2009, in Finland, we detected RNA of European and Siberian subtypes of TBEV in Microtus agrestis and Myodes glareolus voles, respectively. Persistence in rodent reservoirs may contribute to virus overwintering.

Many infectious diseases are zoonoses, that is, they can be transmitted between vertebrate animals and humans. More than a fifth of zoonotic pathogens are transferred from one host to another by vectors, which are often blood-sucking arthropods, such as ticks. In Europe, Lyme borreliosis, spread by Ixodes ricinus tick, is the most prevalent tick-borne zoonosis. I. ricinus spreads also other zoo...

A national crowdsourcing-based tick collection campaign was organized in 2015 with the objective of producing novel data on tick distribution and tick-borne pathogens in Finland. Nearly 20 000 Ixodes ticks were collected. The collected material revealed the nationwide distribution of I. persulcatus for the first time and a shift northwards in the distribution of I. ricinus in Finland. A subset ...
متن کاملTick-borne encephalitis virus in ticks detached from humans and follow-up of serological and clinical response.
The risk of tick-borne encephalitis virus (TBEV) infection after a tick bite remains largely unknown. To address this, we investigated the presence of TBEV in ticks detached from humans in an attempt to relate viral copy number, TBEV subtype, and tick feeding time with the serological and clinical response of the tick-bitten participants. Ticks, blood samples, and questionnaires were collected ...
