People have ecosystems within their bodies consisting of tiny microbes that are unique to them, individually. Similarly, metro and subway transit systems within cities have their own ecosystems, too, that can be impacted by humans. Passengers often exchange microbes in city subway systems. Cities have "fingerprints” of viruses and bacteria that identify them. _ Related: Study tracks growing list of COVID-19 symptoms in real time_ Research on the subject may even help scientists to discover new compounds that could be used as antibiotics or for drug development. _ Related: [Rotting feral pig carcasses teach scientists what happens …

Studies found that cities closer to the ocean have more marine microbes within their transit systems, while those near parks have more plant microbes.
