Importance of localized skin infection in tick-borne encephalitis virus transmission.
The results indicate that the local skin site of tick feeding is an important focus of viral replication early after TBE virus transmission by ticks, and supports the hypothesis that viremia is a product, rather than a prerequisite, of tick-borne virus transmission. Expand
Non-viraemic transmission of tick-borne encephalitis virus: a mechanism for arbovirus survival in nature
To reproduce natural conditions of virus transmission, infected and uninfected vectors (ticks) of tick-borne encephalitis virus, the most important arbovirus in Europe, were allowed to feed together on unin infecteded wild vertebrate hosts. Expand
Genetic relatedness of Sindbis virus strains from Europe, Middle East, and Africa.
The finding of strains similar to prototype SIN in Middle Sweden and of strains in South Africa relating to the northern cluster of SIN strains supports the notion of the dispersal of Sin by migrating birds as previously suggested for New World alphaviruses. Expand

It is demonstrated that natural hosts having neutralizing antibodies to TBE virus (and no detectable viremia) can still support virus transmission between infected and uninfected ticks feeding closely together on the same animal. Expand
Recombination in Tula Hantavirus Evolution: Analysis of Genetic Lineages from Slovakia
Genetic data suggest that homologous recombination events occurred in the evolution of hantaviruses, particularly in the eastern Slovakian TUL lineage. Expand
The role of small rodents and hedgehogs in a natural focus of tick-borne encephalitis.

- Bulletin of the World Health Organization
It was found that the frequency of antibodies was considerably higher in hedgehogs than in small rodents; this may be due to the longer life-cycle of the former, which makes the probability of reinfection greater. Expand
ISOLATION FROM IXODES PERSULCATUS TICKS OF CYTOPATHIC AGENTS (KEMEROVO VIRUS) DIFFERING FROM TICK-BORNE ENCEPHALITIS VIRUS AND SOME OF THEIR PROPERTIES.
Family outbreak of alimentary tick-borne encephalitis in Slovakia associated with a natural focus of infection

A family outbreak of tick-borne encephalitis involving 7 people, all of them hospitalized, was observed in the district of Považská Bystrica (central Slovakia), where the disease was associated with the drinking of unboiled goat milk and ticks recovered from places where goats were grazing. Expand
Change in phenotype of tick-borne encephalitis virus following passage in Ixodes ricinus ticks and associated amino acid substitution in the envelope protein.
The phenotypic change from virulence to attenuation was associated with a single amino acid codon change in the viral envelope gene of TBE virus, and it is recognised that amino acid substitutions in other parts of the viral genome have not been ruled out. Expand
