Так же не до конца ясно, как паразитозы могу влиять на свойства пробиотических препаратов. Целью данного исследования было изучение влияние лямблий и криптоспоридий на кишечную микробиоту экспериментальных животных при изучении пробиотиков. В кишечной микробиоте экспериментальных мышей с успешно интегрированными пробиотическими штаммами Lactobacillus sakei иLactococcus lactisпосле протозойной инвазии криптоспоридиями и лямблиями данные штаммы не обнаружены, что может свидетельствовать об антагонистическом действии криптоспоридий и лямблий в отношении этих штаммов.</p></abstract><trans-abstract xml:lang="en"><p>There is relatively little information on the eﬀect of probiotic supplements used in helminthiasis, and one can only guess how much probiotics can aﬀect helminthiasis and associated inﬂammatory and immunopathological changes in the gastrointestinal tract, as well as how parasitosis can aﬀect the properties of probiotic preparations. The aim of this study was to study the eﬀect of Giardia and Cryptosporidium on the intestinal microbiota of experimental animals in the study of probiotics. In the intestinal microbiota of experimental mice with successfully integrated probiotic strains of Lactobacillus sakei and Lactococcus lactis, cryptosporidium and giardia, which may indicate the antagonistic eﬀect of cryptosporidium and giardia did not ﬁnd these strains after protozoal invasion against these strains.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пробиотики</kwd><kwd>криптоспоридии</kwd><kwd>лямблии</kwd><kwd>микробиом</kwd></kwd-group><kwd-group xml:lang="en"><kwd>probiotics</kwd><kwd>cryptosporidium</kwd><kwd>giardia</kwd><kwd>microbiome</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено в рамках договора с НПО «ЛИТ» №12/31-19 от 14 июня 2019 г.</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">Leung JM, Graham AL, Knowles SCL.
