    Features of the intestinal microbiota in children with intestinal parasitosis by O. V. Kovaleva, L. A. Lityaeva

    Published 2021-07-01
    “…To identify the quantitative content of the main groups of normobiota, species composition and spectrum of opportunistic bacteria and viruses, the method of gas chromatography-mass spectrometry of intestinal microbial markers was used.It was found that in children with intestinal parasitosis, already at the prenatal stage of the formation of the intestinal microbiota, risk factors were recorded that negatively affect the composition of the forming microbiota, associated with functional disorders of the digestive tract from the first days of life.The degree of deficiency of normobiota, as well as the spectrum of opportunistic bacteria in children with parasitic invasions, was greater: 14 types of bacteria in combination with herpes viruses versus 9 in the comparison group. …”
