About 12,000 bacteria and viruses collected in a sampling from public transit systems and hospitals around the world from 2015 to 2017 had never before been identified, according to a study by the International MetaSUB Consortium, a global effort at tracking microbes that is led by Weill Cornell Medicine investigators.
Researchers use genomic sequencing technique to detect presence of various microbes
About 12,000 bacteria and viruses collected in a sampling from public transit systems and hospitals around the world from 2015 to 2017 had never before been identified, according to a study by the International MetaSUB Consortium, a global effort at tracking microbes that is led by Weill Cornell Medicine investigators.
For the study, published May 26 in
Cell, international investigators collected nearly 5,000 samples over a three-year period across 60 cities in 32 countries and six continents. The investigators analyzed the samples using a genomic sequencing technique called shotgun sequencing to detect the presence of various microbes, including bacteria, archaea (single-celled organisms that are distinct from bacteria), and viruses that use DNA as their genetic material. (Other types of viruses that use RNA as their genetic material, such as SARS-CoV-2, the virus that causes COVID-19, would not
