[The characteristics of the accumulation and the possibility of the long-term preservation of the tick-borne encephalitis virus in ixodid ticks].

: A method for tick-borne encephalitis virus reproduction was developed in female Ixodes ticks in the period of postlarval development, if they were kept at elevated temperature (23-37 degrees C). It ensures further conservation of the agent in carriers by decreasing tick maintenance temperature to 4 degrees C.
