It was established that microorganisms of the Moraxella genius have strongest adhesive characteristic. The high hemolytic and hemagglutination activity is inherent in microorganisms of the Staphylococcus and Streptococcus genius. In the case of isolation from patients microbial associations the clinical symptoms and pathogenicity factors of microbes-associates were more apparent.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Резюме.</bold> Изучены следующие факторы патогенности у микроорганизмов, превалирующих при острых воспалительных процессах верхних дыхательных путей: адгезивные свойства, гемолитическая, гемагглютинирующая, нейраминидазная активность. Установлено, что наиболее выраженной адгезивностью обладают микроорганизмы рода Moraxella. Высокая гемолитическая и гемагглютинирующая активности присущи микроорганизмам родов Staphylococcus и Streptococcus. При выделении от больных микробных ассоциаций клинические проявления заболевания были более выраженными, так же как и факторы патогенности ассоциантов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Staphylococcus</kwd><kwd>Streptococcus</kwd><kwd>Moraxella</kwd><kwd>factors of pathogenicity</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>cтафилококки</kwd><kwd>стрептококки</kwd><kwd>моракселлы</kwd><kwd>факторы патогенности</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
