Контроль помёта на наличие антибиотикорезистентных бактерий является актуальной задачей для минимизации рисков распространения антимикробной резистентности в окружающей среде. Целью исследования являлось изучение видового состава и профилей антибиотикорезистентности бактерий, выделенных из помёта здоровой сельскохозяйственной птицы на семи предприятиях Сибирского региона. Проведено исследование 280 проб помёта от здоровых кур-несушек и цыплят-бройлеров разного возраста. Индикацию микроорганизмов проводили общепринятыми в микробиологии методами с использованием простых и дифференциально-диагностических питательных сред, идентификацию до вида осуществляли с применением технологии матричной лазерной десорбционной ионизационной времяпролетной масс-спектрометрии (MALDI-ToF MS). Резистентность бактерий изучали диско-диффузным методом. Изучена чувствительность 550 выделенных изолятов к 26 антибактериальным препаратам различных фармакологических групп. На основании исследований установлено, что в микробиоценозе помёта здоровых кур превалируют бактерии семейства Enterobacteriaceae — 46,0 % (Escherichia coli, Proteus mirabilis) и Staphylococcaceae — 29,8 %. При изучении профилей их антибиотикорезистентности наибольшая устойчивость к исследуемым антибиотикам выявлена у представители условно-патогенной микрофлоры из семейства Staphylococcaceae: 95—100 % культур были резистентны к пенициллинам, фторхинолонам, тетрациклинам, макролидам и линкозамидам, при этом в 100 % случаях они были полирезистентными. Среди представителей семейства Enterobacteriaceae свыше 50 % изолятов Escherichia coli и Proteus mirabilis были устойчивы к антибиотикам из группы пенициллинов и фторхинолонов, полирезистентность выявлена у 16,6 % и 13,3 % культур, соответственно.</p></abstract><trans-abstract xml:lang="en"><p>Bird droppings, widely used as organic fertilizer in agriculture, pose a serious threat to human health and the environment due to the presence of antibiotic residues and antibiotic resistance genes. Litter monitoring for the presence of antibiotic-resistant bacteria is an urgent task to minimize the risks of spreading antimicrobial resistance in the environment. The aim of the study was to study the species composition and antibiotic resistance profiles of bacteria isolated from the droppings of healthy poultry at seven enterprises in the Siberian region. A study of 280 litter samples from healthy laying hens and broiler chickens of different ages was conducted. The indication of microorganisms was carried out by methods generally accepted in microbiology using simple and differential diagnostic nutrient media, identification to the species was carried out using the technology of matrix laser desorption ionization time-of-flight mass spectrometry (MALDI-ToF MS). Bacterial resistance was studied by the disco-diffuse method. The sensitivity of 550 isolated isolates to 26 antibacterial drugs of various pharmacological groups was studied. Based on research, it was found that the microbiocenosis of the litter of healthy chickens is dominated by bacteria of the Enterobacteriaceae family — 46,0 % (Escherichia coli, Proteus mirabilis) and Staphylococcaceae — 29,8 %. When studying their antibiotic resistance profiles, representatives of the opportunistic microflora from the Staphylococcaceae family showed the greatest resistance to the studied antibiotics: 95—100 % of the cultures were resistant to penicillins, fluoroquinolones, tetracyclines, macrolides and lincosamides, while in 100 % of cases they were polyresistant. Among the representatives of the Enterobacteriaceae family, over 50 % of Escherichia coli and Proteus mirabilis isolates were resistant to antibiotics from the penicillin and fluoroquinolone group, polyresistance was detected in 16,6 % and 13,3 % of cultures, respectively.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>антибиотикорезистентность</kwd><kwd>микроорганизмы</kwd><kwd>помёт</kwd><kwd>сельскохозяйственная птица</kwd><kwd>бактерии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>antibiotic resistance</kwd><kwd>microorganisms</kwd><kwd>droppings</kwd><kwd>agricultural poultry</kwd><kwd>bacteria</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках государственного задания Министерства науки и высшего образования Российской Федерации (проект FNUN-2025-0004).</funding-statement><funding-statement xml:lang="en">The research was carried out within the framework of the state assignment of the Ministry of Science and Higher Education of the Russian Federation (FNUN-2025-0004).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Фисинин, В.
