Flaviviridae): Западно-Европейский (ассоциирован с клещом. I. ricinus), Сибирский и Дальневосточный (ассоциированы с таежным клещом. I. persulcatus). Одним из основных путей циркуляции. ВКЭ в природе является невиремическая трансмиссия вируса между зараженными и незараженными клещами во время совместного питания, на одном прокормителе. Ранее было обнаружено, что эффективность невиремической трансмиссии, между клещами I. ricinus типового штамма Западно-Европейского субтипа «Hypr» (Hypr) составляет. 60 %, в то время как для. типового штамма Сибирского субтипа «Васильченко» (Vs) - только 5 %. Для. установления вирусных детерминант, определяющих эффективность трансмиссии, мы. создали ряд рекомбинантных вирусов с взаимозамененными генами структурных (str) и. неструктурных (ns) белков. Рекомбинантный вирус Hypr[str]Vs[ns] обладал 70 % эффективностью невиремической. трансмиссии. Введение отдельных структурных генов штамма Hypr в ифекционный клон Vs также увеличивало эффективность трансмиссии до 33 %. Таким образом, нами показано, что эффективность невиремической трансмиссии ВКЭ определяется, прежде всего, свойствами структурных белков вируса.</p></abstract><trans-abstract xml:lang="en"><p>There are 3 subtypes of tick-borne encephalitis virus (TBEV) distinguished, at present time: European (EU), Siberian (SIB) and Far Eastern (FE). The former one is associated with Ixodes ricinus tick, whereas the latter two - with I. persulcatus. The circulation of TBEV in nature is mediated by the non-viraemic transmission, between infected and. uninfected ticks co-feeding on the same hosts and. it was shown that transmission rate of «Hypr» strain (EU subtype) is much higher than rate of «Vasilchenko» strain (SIB subtype) - 60 and 5 % respectively. To reveal the viral determinants of transmission efficacy, we constructed the series of recombinant viruses with gradually exchanged genes coding structural (str) and. non-structural (ns) viral proteins. The recombinant virus Hypr[str]Vs[ns] achieved the rate of non-viraemic transmission of 70 %. The introduction of separate structural genes of Hypr into Vs infectious clone has enhanced the transmission efficacy as well, though not to such extent as entire structural region but up to 33 % only. Thus, it was shown that efficacy of non-viraemic transmission of TBEV depends from properties of viral structural proteins mainly.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вирус клещевого энцефалита</kwd><kwd>трансмиссия</kwd><kwd>рекомбинантный вирус</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tick-borne encephalitis virus</kwd><kwd>transmission</kwd><kwd>recombinant virus</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Борисов В.А., Малов И.В., Ющук Н.Д.
