Биологические образцы были собраны от 15 видов диких уток.

To isolate influenza A virus isolates from cloacal smears, cultivation on developing chicken embryos was used in three consecutive passages, following a standard procedure.</p><p>Cloacal smears were collected from 3,733 individuals of the Anatidae family. 163 A AIV VP isolates were isolated from samples taken in autumn, while 2 isolates were isolated in spring. The analysis of the data showed inter‐annual fluctuations in the infection rate of AIV from 1 to 10 % in different years. </p><p>Varying seasonal and inter‐annual dynamics of wild duck infection were determined in the study area and it can be assumed that this is caused by the specific characteristics of the carriers and environmental conditions. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>Миграция</kwd><kwd>сезонная динамика</kwd><kwd>межгодовая динамика</kwd><kwd>вирус гриппа птиц</kwd><kwd>экология птиц</kwd><kwd>дикие утки</kwd><kwd>юг Западной Сибири</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Migration</kwd><kwd>seasonal dynamics</kwd><kwd>inter‐annual dynamics</kwd><kwd>avian influenza virus</kwd><kwd>bird ecology</kwd><kwd>wild ducks</kwd><kwd>southern Western Siberia</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке гранта «Создание актуальной коллекции современных вирусов болезни Ньюкасла (ВБН) для разработки иммунологических биопрепаратов» РНФ № 24‐24‐00367.
