title: [Modeling a persistent infection by tick-borne encephalitis virus strains in a cell culture of the clawed toad].
abstract: Differences in the ability of 12 tick-borne encephalitis virus strains to induce persistent infection in the culture of clawed frog cells incubated at 26-32 degrees C were shown. In 8 strains the process of persistence was accompanied by the stable preservation of the infectious virus in the culture medium during 10 passages, while in 4 strains the virus disappeared already in passages 3-8.
