article_snippet.sent: Researchers say the results show just how modern lifestyles and diets have changed us -  and that the  bacteria Researchers found could be potentially beneficial to modern society.
article_snippet.sent: That tells us that Western diets and lifestyles have a great impact on us microbiomes', experts at University of San Diego said. '
article_snippet.sent: Studying the microbiomes of people in remote areas may hold the key to understanding microbes we have lost through antibiotics, sealed buildings and lack of exposure to the outdoors,' said study co-author Rob Knight.
article_snippet.sent: This information revealed, for the first time, the species of bacteria that co-exist with people who have never been exposed to industrialized society, including Western food and antibiotics. '
article_snippet.sent: Our findings emphasize the need for extensive characterization of the function of the microbiome and resistome in remote nonwesternized populations before globalization of modern practices affects potentially beneficial bacteria harbored in the human body,' the researchers wrote.
article_snippet.sent: From this, researchers were able to identify all of the bacterial species that make up the skin, mouth and gut microbiomes of people who had never been exposed to Western diets, antibiotics or other environmental factors that make up life in industrialized societies.
article_snippet.sent: The researchers then compared these non-Westernized microbiomes to the microbiomes of people living in Western society and people living in villages in the midst of transition from isolation to urban lifestyles.
article_snippet.sent: Bacteria isolated from Yanomami microbiomes carried genes that confer resistance to man-made antibiotics, despite the fact that Bacteria were never previously exposed to antibiotics.
article_snippet.sent: This finding suggests that many bacterial species contain antibiotic resistance genes naturally, even without the selective pressure of antibiotic use.
article_snippet.sent: What happens in Western cultures, The researchers hypothesize, is antibiotic use simply gives naturally resistant bacteria a survival advantage over non-resistant bacteria.
article_snippet.sent: The researchers say the study could help develop new medical treatments. '
article_snippet.sent: First of all, the study gives us a glimpse of what us microbiomes might have looked like before us modern habits began to impact the beneficial bacteria that call us home. '
article_snippet.sent: Studies like this one help us better understand what factors can alter a microbiome and the effect those changes can have on a person's health — information researchers need to guide efforts to manipulate the microbiome to treat disease and restore health.'
