Each city has its unique microbiota

Our microbiota is influenced by microorganisms in our city and vice versa, underlines a study published in the journal Cells. Thanks to a microbial inventory in 60 cities, American researchers have been able to genetically map cities around the world but also to discover a microscopic biodiversity that had hitherto been unsuspected.

A city is above all a place where a large human population is concentrated. Every day, as we walk the streets of a city and meet its inhabitants, we come into contact with their surroundings. Involuntary exchanges with different external environments take place. They allow us to transmit but also to receive many microorganisms such as bacteria, viruses or fungi. Our microbiomes, all the microorganisms of an individual, are thus modeled on the places where we live.

Based on these observations, researchers at Cornwell University in New York have decided to genetically map some 60 cities around the world. Their goal ? Discover new species of microorganisms growing in cities and better understand how the microbiomes of each city are formed. The study published in the journal Cells is open access ….
