Целью настоящего исследования является анализ таксономического и метаболического состава микробиоты кишечника белой куропатки с использованием современных молекулярно-генетических методов, в частности NGS-секвенирования. Объектом исследования послужило содержимое подвздошной кишки и слепых отростков кишечника белой куропатки, добытой в зимний период на территории Малоземельской тундры Ненецкого автономного округа. Результаты исследований продемонстрировали целый спектр отличий, связанных с таксономическим и функциональным разнообразием микробиоты тонкой и толстой кишки белой куропатки. При этом в слепых отростках птиц отмечалось существенно более высокое количество бактерий с целлюлозолитическими свойствами (семейств Clostridia vadinBB60, Oscillospiraceae, Lachnospiraceae). Этот факт может представлять интерес в контексте поиска штаммов микроорганизмов для разработки биопрепаратов с пробиотическими и ферментативными свойствами. Также в кишечнике белой куропатки детектированы представители условно-патогенной микробиоты (семейств Streptococcaceae и Helicobacteraceae), часто вызывающей заболевания на фоне ослабления иммунитета. В слепых отростках по сравнению с подвздошной кишкой наблюдалось более высокое количество метаболических путей, ассоциированных с энергетическим обменом (FUCRHAMCAT-PWY (p≤0,005), FUCCAT-PWY (p≤0,001), GLUCUROCAT-PWY (p≤0,005)), антиоксидантной активностью (NAD-BIOSYNTHESIS-II (p≤0,005), PYRIDNUCSALPWY, PYRIDNUCSYN-PWY, PYRIDOXSYN-PWY (p≤0,05)), биосинтезом витаминов и кофакторов. Результаты проведенных исследований указывают на значительный метаболический потенциал микробиома кишечника белой куропатки, особенно его в слепых отростках.</p></abstract><trans-abstract xml:lang="en"><p>Despite a significant amount of research on the digestive system of birds, grouse, which includes the, remain insufficiently studied in this context. One of the characteristic features of the digestive physiology of partridge (Lagopus lagopus) is the enlarged cecum compared to representatives of other families. The purpose of this study is to analyze the taxonomic and metabolic composition of the intestinal microbiota of the white partridge using modern molecular genetic methods, in particular NGS sequencing. The object of the study was the contents of the ileum and caecal appendages of the intestine of a white partridge, harvested in winter on the territory of the Malozemelskaya tundra of the Nenets Autonomous Okrug. The research results demonstrated a range of differences related to the taxonomic and functional diversity of the microbiota of the small and large intestine of the white partridge. At the same time, a significantly higher number of bacteria with cellulolytic properties (Clostridia vadinBB60, Oscillospiraceae, and Lachnospiraceae families) was observed in the blind processes of birds. This fact may be of interest in the context of the search for strains of microorganisms for the development of biological products with probiotic and enzymatic properties. Representatives of opportunistic microbiota (Streptococcaceae and Helicobacteraceae families) have also been detected in the intestines of the white partridge, which often causes diseases due to weakened immunity. In the cecum, compared with the ileum, there was a higher number of metabolic pathways associated with energy metabolism (FUC-RHAMCATPWY (p&lt;0.005), FUCCAT-PWY (p&lt;0.001), GLUCUROCAT-PWY (p&lt;0.005)), antioxidant activity (NAD-BIOSYNTHESIS-II (p&lt;0.005), PYRIDNUCSAL-PWY, PYRIDNUCSYN-PWY, PYRIDOXSYN-PWY (p&lt;0.05)), biosynthesis of vitamins and cofactors. The results of the conducted studies indicate a significant metabolic potential of the intestinal microbiome of the white partridge, especially in its blind processes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>белая куропатка</kwd><kwd>микробиом кишечника</kwd><kwd>метаболический потенциал</kwd><kwd>NGS-секвенирование</kwd><kwd>PICRUSt2</kwd><kwd>перспективные пробиотические штаммы.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>willow grouse</kwd><kwd>gut microbiome</kwd><kwd>metabolic potential</kwd><kwd>NGS sequencing</kwd><kwd>PICRUSt2</kwd><kwd>promising probiotic strains</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">Воронин Р.Н.
