Small gut intestine microbiota in adolescent girls with obesity

Abstract

Aim. To characterize the small intestine microbiome in adolescent girls with obesity according to gas chromatography-mass spectrometry of microbial markers (CMSMM). Material and Methods. The research involved 72 adolescents (girls) 12-17 years old, half of the children (group 1) were obese, the other half (group 2) were not obese, as well as did not have any chronic diseases. Microbial markers in blood samples were examined by the CMSMM method. In order to examine correlation between the small intestine microbiota and obesity, a logistic model was formed. ROC analysis was used to determine possible effects of microorganisms on obesity. Results. There were found significant differences in the small intestine microbiome of obese girls, and alike microbiocenosis of children with normal body weight. Obese adolescent girls had higher levels of Nocardia asteroides 504.14[296; 1015] cells/g×10⁵ and Candida spp 241.85[198.09;629.97] cells/g×10⁵. Microorganisms of the opportunistic flora such as Actinobacteria, Firmicutes, Proteobacteria and microscopic fungi, as well as herpesviruses were significantly deficient. Conclusions. Nocardia asteroides and Candida spp. are associated with obesity. The risk of obesity in adolescent girls increases with a growing number of above-mentioned microorganisms.
