Нарушения кишечной микробиоты при расстройствах аутистического спектра: новые горизонты в поиске патогенетических подходов к терапии. Часть 1. Особенности кишечной микробиоты при расстройствах аутистического спектра

The first part of the literature review on the role of intestinal microbiota dysbiosis in the pathogenesis of autism spectrum disorders (ASD) includes recent data published in the literature on the features of the quantitative and qualitative composition of the intestinal microbiota in patients with autism. It was shown that an excessive presence of Clostridium was detected in ASD, and evidence was presented showing the possible participation of these bacteria in the development of autism symptoms. Contradictory research results on an increase in a number of other pathogenic bacteria and, conversely, a decrease in the number of bacteria necessary to maintain the normal functioning of the intestine and the host organism as a whole are presented. The possible role of Candida albicans in ASD, requiring further study, is reported. Possible causes of contradictions in the results of studies on this topic are discussed.
