Viruses, Vol. 11, Pages 1069: In Vivo Characterization of Tick-Borne Encephalitis Virus in Bank Voles (Myodes glareolus) Viruses doi: 10.3390/v11111069 Authors: Michelitsch Tews Klaus Bestehorn-Willmann Dobler Beer Wernike Tick-borne encephalitis is the most important tick-transmitted zoonotic virus infection in Eurasia, causing severe neurological symptoms in humans. The causative agent, the tick-borne encephalitis virus (TBEV), circulates between ticks and a variety of mammalian hosts. To study the interaction between TBEV and one of its suspected reservoir hosts, bank voles of the Western evolutionary lineage were inoculated subcutaneously with either one of eight TBEV strains or the related attenuated Langat virus, and were euthanized after 28 days. In addition, a subset of four strains was characterized in bank voles of the Carpathian linage. Six bank voles were inoculated per strain, and were housed together in groups of three with one uninfected in-contact animal each. Generally, most bank voles did not show any clinical signs over the course of infection. However, one infected bank vole died and three had to be euthanized prematurely, all of which had been inoculated with the identical TBEV strain (Battaune 17-H9, isolated in 2017 in Germany from a bank vole). All inoculated animals seroconverted, while none of the in-contact animals did. Viral RNA was detected via real-time RT-PCR in the whole blood samples of 31 out of 74 inoculated and su...

AbstractPurpose of ReviewIn this review, we present the overview of emerging and neglected viruses associated with liver involvement.Recent FindingsHepatitis E virus (HEV) emerged in the last two decades, causing hepatitis in many parts of the world. Moreover, liver involvement was also described in some emerging arboviral infections. Many reports showed dengue-associated liver injury; however, chikungunya, West Nile, tick-borne encephalitis, and Zika virus are rarely associated with clinically manifest liver disease. In addition, some neglected highly prevalent viruses such as adenoviruses and parvovirus B19 are capable o...

Intensive contact between herdsmen and their livestock, together with the use of pastures without fencing, allows contact between wildlife, domestic animals and humans, thus creating ideal conditions for epizoonos...

Transmission of vector borne pathogens are particularly sensitive to these changes due to the complexity of their cycle, where the transmission of a...

Abstract Tick-borne encephalitis virus (TBEV) is a zoonotic agent causing severe encephalitis. The transmission cycle involves the virus, the Ixodes tick vector, and a vertebrate reservoir, such as small mammals (rodents, or shrews). Humans are accidentally involved in this transmission cycle. Tick-borne encephalitis (TBE) has been a growing public health problem in Europe and Asia over the past 30 years. The mechanisms involved in the development of TBE are very complex and likely multifactorial, involving both host and viral factors. The purpose of this review is to provide an overview of the current lite...

TBEV represents a pathogen of high zoonotic potential and an emerging global threat. There are three known subtypes of TBEV: Far-Eastern, Siberian and European. Since 2001 there have been suggestions that two new subtypes may be distinguished: “178-79” and “886-84”. These assumptions are based on the results of the envelope gene fragment sequencing (Zlobin et al., 2001; Kovalev and...

Tick-borne encephalitis (TBE) is one of eight zoonoses carried by ticks in Norway (the others are Anaplasmosis, Babesiosis, Louping ill, Lyme borreliosis, Relapsing fever, Rickettsial spotted fever and Tularemia).  As displayed in the following graphs, rates of human TBE are considerably lower than those of other tick-borne diseases in Norway, and below TBE rates reported by neighboring countries.

Purpose: Pathogens of the genera Anaplasma, Borrelia and Rickettsia, and Tick-borne Encephalitis virus (TBEV) may be associated to various tick species which are hematophagous ectoparasites potentially hosted by any terrestrial vertebrate, humans included. This peculiarity makes ticks potential horizontal vectors of zoonotic importance.
