Terrifying microbe map of New York’s subway system reveals superbugs, anthrax and bubonic plague

The New York City subway is cramped with people, but a new study shows that the underground system may be much more crowded than we realized.

Scientists from Weill Cornell Medical College have unveiled their findings after 18 months swabbing turnstiles, ticket kiosks, railings and benches for DNA on the world's largest transport system.

They found 15,152 different types of microorganisms that share the train with its 5.5 million riders, including bubonic plague, dysentery and meningitis.
