Abstract
Females and males of ixodid ticks (Ixodes and Dermacentor) infected parenterally with the tick-borne encephalitis virus at the adult or nymphal phase and containing the virus in the saliva are able to transmit the agent in the first minutes after the bite of the sensitive animal host. Preservation of the cement conus produced by saliva in the animal skin enhances the infection intensity because the quantity of the virus in the conus is comparable with that in the tick's body. The virus quantity in the fluid saliva, excreted by I. persulcatus females and measured during different periods of bloodsucking (at least during the first three days), increases 10 to 100 times in comparison with a comparable volume of hungry ones.
