 the intestinal microbiota regulates our physiology and metabolism through its ability to affect the microbiota. Probiotics confer health benefits that may arise from their ability to affect the intestinal microbiota. High throughput screening of the intestinal microbiota was conducted and integrated with serum lipidomic profiling data to study the impact of probiotic intervention on the intestinal ecosystem and to explore the associations between the intestinal bacteria and serum lipids. A comprehensive intestinal microbiota analysis was performed using a phylogenetic microarray before and after lactobacillus ramnosis GG intervention. No other changes in the composition or stability of the microbiota were detected. After the intervention, lactobacilli returned to their initial levels. Previously reported associations between the gut microbiota and lipid profiles were confirmed. Uncultured phylotypes of ruminococcus navus group were found to have a strong positive correlation with polyunsaturated serum triglycerides of dietary origin. Additionally, a strong positive correlation was detected between. This article was authored by Leo Lotti and Salonen, Rina A. Kekonen, and others. We are article.tv, links in the description below.
