    <p>Аннотация. Цель настоящей работы – апробация устройства для изучения микробиома желудочно-кишечного тракта млекопитающих. Исследование количественного и качественного состава микробиоты органов пищеварения – одно из перспективных направлений в метагеномике. Полученные знания об организации генома микробиоценоза, определение видового состава и изучение метаболических взаимосвязей между его представителями не только позволяют расширить понимание его роли в процессе эволюции, видо- и породообразования, но и дают научно аргументированную основу для целенаправленного изменения микробиома с целью формирования фенотипа (оптимизация биоконверсии корма, повышение общей резистентности и т. д.). Научная новизна. Впервые через хроническую фистулу выделены, культивированы и описаны основные характеристики целлюлозолитических бактерий, выделенных из химуса слепой кишки кролика. Методы. Для проведения исследований, направленных на изучение микробиома млекопитающих и его коррекции, возникает необходимость в разработке методов получения образцов микробиома от экспериментальных животных. Для получения доступа к химусу слепой кишки 7 кроликам на срок до 3 месяцев были установлены разработанные в ФГБНУ НИИПЗК хронические фистулы. После установки фистул у животных не отмечалось никаких негативных проявлений, не было обнаружено изменений в аппетите, на 9-е сутки определено полное заживление раны кожи. В ходе диагностических лапаротомий, проведенных через 3 месяца после установки фистул, ни у одного исследуемого животного не выявлено патологических процессов. Результаты. Изучены характеристики целлюлозолитических бактерий слепой кишки кролика Butirivibrio fibrisolvens и Ruminococcus flavefaciens. Приведены данные по их ферментному воздействию на составляющие рационов, продуктам ферментации, сбраживанию и образованию органических веществ и химических соединений.</p>

    <p>Abstract. The purpose of this work is to approve a device for studying the microbiome of the gastrointestinal tract of mammals. The study of the quantitative and qualitative composition of the digestive tract microbiota is one of the promising directions in metagenomics. Knowledge obtained about the organization of microbiocenosis genome, the determination of species composition and study of metabolic relationships between its representatives not only expand the understanding of its role in the process of evolution, speciation and breeding but also provide a scientifically substantiated basis for targeting changes in the microbiome to form a phenotype (optimization of feed bioconversion, increasing overall resistance, etc.). Scientific novelty. For the first time, the main characteristics of cellulolytic bacteria isolated from the chyme of the rabbit cecum were isolated, cultured and described through a chronic fistula. Methods. In order to carry out research aimed to study mammalian microbiome and its correction, the need arises to develop methods of obtaining microbiome samples from experimental animals. To obtain access to the chyme of the cecum in 7 rabbits for up to 3 months the chronic fistulas developed in Scientific Research Institute of Fur-Bearing Animal Breeding and Rabbit Breeding n. a. V. A. Afanas’ev were installed. No negative manifestations were observed in the animals after installation of the fistulas, no changes in appetite were detected, and complete healing of the skin wound was determined on the 9th day. Diagnostic laparotomies performed 3 months after fistula placement revealed no pathological processes in any of the studied animals. Results. Characteristics of cellulolytic bacteria of the rabbit cecum Butirivibrio fibrisolvens and Ruminococcus flavefaciens were studied. Data on their enzymatic effects on dietary components, fermentation products, digestion and formation of organic substances and chemical compounds are presented.</p>
