In particular, the literature contains data on the composition of the gut microbiota in multiple sclerosis (MS). However, the body's microbiome is not limited to the gut microbiota. Of particular interest are the body fluids that are in direct contact with the nervous tissue, such as cerebrospinal fluid (CSF). In our previous studies, we have already analyzed the CSF in different variants of MS course and found the markers of different microbes, which confirms the hypothesis of the association of MS with polymicrobial infection. No less interesting is the transitional state – radiologically isolated syndrome (RIS), in which less attention was paid to analyzing the microbiome.</p><sec><title>Objective</title><p>Objective: to evaluate the content of microbial metabolites in the CSF of individuals with RIS and in the control group.</p></sec><sec><title>Material and methods</title><p>Material and methods. The content of microbial markers in the CSF was determined using gas chromatography-mass spectrometry in 10 individuals with RIS and in 10 individuals in the control group.</p></sec><sec><title>Results</title><p>Results. We found a statistically significant increase in the content of microbiota markers in the CSF of individuals with RIS, namely a statistically significant increase in the content of markers of Epstein–Barr virus, Propionibacterium acnes bacteria, Pseudomonas, Moraxella and Acinetobacter.</p></sec><sec><title>Conclusion</title><p>Conclusion. The results of this study are consistent with the hypothesis of a possible association between MS and polymicrobial infection, particularly infection with Epstein–Barr virus.</p></sec></abstract><trans-abstract xml:lang="ru"><p>За последние десять лет получено большое количество данных о роли кишечной микробиоты в развитии заболеваний нервной системы, в частности, в литературе имеются данные о составе кишечной микробиоты при рассеянном склерозе (РС). Однако микробиом организма не ограничивается только лишь кишечной микробиотой. Особый интерес вызывают среды организма, которые находятся в непосредственном контакте с нервной тканью, такие как цереброспинальная жидкость (ЦСЖ). В наших предыдущих исследованиях мы уже провели анализ ЦСЖ при различных вариантах течения РС и обнаружили содержание маркеров различных микробов, что подтверждает гипотезу об ассоциации РС с полимикробной инфекцией. Не меньший интерес вызывает переходное состояние – радиологически изолированный синдром (РИС), изучению микробиома при котором уделено меньше внимания.</p><p>Цель исследования – оценка содержания микробных метаболитов в ЦСЖ лиц с РИС и представителей контрольной группы.</p><sec><title>Материал и методы</title><p>Материал и методы.

Нами показано статистически значимое увеличение содержания маркеров микробиоты в ЦСЖ у лиц с РИС, а именно – выявлено статистически значимое увеличение уровня маркеров вируса Эпштейна–Барр, бактерий Propionibacterium acnes, а также Pseudomonas, Moraxella и Acinetobacter.</p></sec><sec><title>Заключение</title><p>Заключение.
