По результатам эколого-эпизоотологического мониторинга в 2006–2012 гг. отслежены видовой состав, динамика численности и характера распределения птиц водного и антропогенового комплексов, кровососущих комаров и иксодовых клещей. Рассматриваются возможные причины расширения нозоареала ЛЗН, связанные с экологией перелетных птиц, зимующих в Африке. Устойчивая циркуляция вируса в интразональных пойменных биоценозах способствует формированию вторичных природных очагов лихорадки Западного Нила и приводит к эпидемическим осложнениям по этой особо опасной трансмиссивной инфекции. На основе анализа плотности гидрографической сети, структуры фауны и численности птиц и комаров – потенциальных носителей и переносчиков ВЗН, результатов эпизоотологического и эпидемиологического обследования разработана прогностическая картосхема, иллюстрирующая вероятность формирования устойчивых очагов этой инфекции в разных районах области.</p></abstract><trans-abstract xml:lang="en"><p>Local climate change (rise of mean temperatures and amount of precipitation, prolongation of frost-free season) triggers further distribution, and increase in numbers of animals – carriers and vectors of West Nile fever virus in the territory of the Saratov region. Based on the results of ecological-epizootiological monitoring (2006–2012) traced out have been the species composition, abundance dynamics, and character of distribution of birds habitant in aquatic and anthropogenic complexes, mosquitoes and Ixodidae ticks. Investigated are possible causes of West Nile fever nosoarea expansion, related to ecology of migrating birds wintering in Africa. Persistent circulation of the virus in intra-zonal inundated biocoenosis facilitates formation of secondary natural foci of West Nile fever and factors into epidemic complications as regards this particularly dangerous vector-borne infection. On the basis of analytical data concerning hydrographic network density, fauna structure, population numbers of birds and mosquitoes – potential carriers and vectors of WNF, epizootiological and epidemiological surveillance, designed has been expectation-driven forecasting map chart which illustrates possibility of sustainable WNF foci formation in various territories of the Saratov region.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лихорадка Западного Нила</kwd><kwd>птицы</kwd><kwd>комары</kwd><kwd>клещи</kwd><kwd>West Nile fever</kwd><kwd>birds</kwd><kwd>mosquitoes</kwd><kwd>ticks</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">Завьялов Е.В., Шляхтин Г.В., Табачишин В.Г., Якушев Н.Н., Хрустов И.А.
