Rainforest Dwellers and Urbanites Have Consistently Different Microbiomes
This is scientific American sixty seconds science. I'm Alina organ. Brown our microbiomes. The tiny organisms UNISOM that live on us in Innis can influence our health and a recent study looked microbiome composition diversity depending on where and how we live given the same latitude and climate across South America. We found a gradient over bunny stations from a jungle houses hats off. Marion people leaving traditional lifestyles. All the way to a modern CD Lake Manas was the differences in microbes from our houses and from our a skin and differences in exposure to chemicals. Microbiologist Maria Gloria Dominguez Peyot from Rutgers University. She and her colleagues collected samples from people pets pets and spaces in homes like the kitchen bathroom and bedrooms. They analyzed bacteria. Fungi parasites chemicals and they found two trends As you go from the rainforest to a farm to a town to the city of House with increasing using population density we are exposed to a higher diversity of fungi. We carry more diversity of fungi in our skin. Hey Buddy nowhere got. We lose microbial diversity. The study is in the journal Nature Microbiology. Urban homes US more more chemical cleaners than do rural or rainforest homes and they're more likely to be built out of synthetic materials so city residents are burdened with more chemicals including including metabolites of cleaners detergents paints in and on their bodies. In addition the microbes of urban dwellers are far more like each other than they are like the more healthful mix found in the rainforest. Domingos Baeau thinks one reason is that we are two isolated from natural landscapes. We have grown culturally very anti anti dirt. We we call dirt there at the end. You know we call the soil dirt and that already has a connotation of undesirable they are bowl perhaps city living could be a bit healthier with fewer chemicals from cleansers and more microbes from what gets cleaned for scientific.
