Целью работы являлось изучение влияния антиоксидантов различного происхождения на микробиоту и гистоструктуру кишечника белых крыс при воздействии глифосата. Изучение эффективности потенциальных компонентов-кандидатов (сукцинат кальция —25 мг/кг живой массы, фумарат аммония — 25 мг/кг, куркумин —0,04 % от рациона), обладающих антитоксическим действием при отравлении пестицидом глифосатом, проводили на 30 белых крысах, разделенных на 5 групп. При воздействие препарата на основе глифосата регистрировали снижение лакто- и бифидобактерий на 34,4 % (p&lt;0,001) и 36,7 % (p&lt;0,001), возрастание численности эшерихий на 30,0 % (p&lt;0,001) в сравнении с биологическим контролем. В экскрементах животных группы токсического контроля были выявлены дрожжевые грибы, сальмонеллы и гемолитические эшерихии. Наиболее высокий результат при затравке глифосатом показал препарат куркумин. Эффект от фумарата аммония был незначительным, а сукцинат кальция показал наименьшую способность к восстановлению нормального состава микробиоценоза белых крыс при отравлении глифосатом. Гистологическая картина тонкого отдела кишечника крыс биологического контроля без отклонений. В гистологических срезах крыс, получавших только глифосат, в кишечнике наблюдался отек слизистого и подслизистого слоев, очаговые некробиозы эпителия. В кишечнике крыс, получавших глифосат и лечение сукцинатом кальция, отмечался отек слизистой с некробиозом отдельных клеток. У крыс, получавших глифосат и лечение фумаратом аммония, кровенаполнение в кровеносных сосудах ткани сниженное. На некоторых участках ворсин эпителий без ядер с нечеткими контурами. В гистологических срезах крыс, получавших глифосат и лечение куркумином, строение кишечника не отличалось от контроля.</p></abstract><trans-abstract xml:lang="en"><p>Glyphosate is the most widely used broad-spectrum herbicide. The aim of this study was to investigate the effects of various antioxidants on the intestinal microbiota and histostructure of white rats exposed to glyphosate. The efficacy of potential candidate components (calcium succinate at 25 mg/kg body weight, ammonium fumarate at 25 mg/kg, and curcumin at 0,04 % of the diet) with antitoxic effects against glyphosate pesticide poisoning was assessed using 30 white rats divided into 5 groups. Exposure to the glyphosate-based preparation resulted in a 34,4 % (p&lt;0,001) and 36,7 % (p&lt;0,001) decrease in lacto- and bifidobacteria, and a 30,0 % (p&lt;0,001) increase in Escherichia coli counts, compared to the biological control. Yeast fungi, salmonella, and hemolytic Escherichia coli were detected in the feces of animals in the toxic control group. Curcumin demonstrated the highest response to glyphosate. The effect of ammonium fumarate was insignificant, and calcium succinate demonstrated the least ability to restore the normal microbiome composition of white rats poisoned with glyphosate. The histological picture of the small intestine of biological control rats was normal. Histological sections of rats given only glyphosate showed edema of the mucosal and submucosal layers, as well as focal epithelial necrosis. Mucosal edema with individual cell necrosis was observed in the intestines of rats given glyphosate and calcium succinate. Rats given glyphosate and ammonium fumarate showed signs of mucosal edema in the intestines. In histological preparations of rats treated with glyphosate and curcumin, the intestinal structure did not differ from the control.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>интоксикация</kwd><kwd>глифосат</kwd><kwd>белые крысы</kwd><kwd>антиоксиданты</kwd><kwd>микробиоценоз</kwd><kwd>дисбиоз</kwd><kwd>лактобактерии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>intoxication</kwd><kwd>glyphosate</kwd><kwd>white rats</kwd><kwd>antioxidants</kwd><kwd>microbiocenosis</kwd><kwd>dysbiosis</kwd><kwd>lactobacilli</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена за счет гранта, предоставленного Академией наук Республики Татарстан образовательным организациям высшего образования, научным и иным организациям на поддержку планов развития кадрового потенциала в части стимулирования их научных и научно-педагогических работников к защите докторских диссертаций и выполнению научно-исследовательских работ (Соглашение от 22.12.2025 г. № 4/2025-ПД-ВНИВИ).</funding-statement><funding-statement xml:lang="en">the work was carried out with the help of a grant provided by the Academy of Sciences of the Republic of Tatarstan to higher education institutions, scientific and other organizations to support plans for the development of human resources in terms of stimulating their scientific and scientific-pedagogical staff to defend doctoral dissertations and carry out research work (Contract No 4/2025-PD-VNIVI of December 22, 2025).</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">Sutton K.
