Researchers at Columbia University found that mice living in the basements of New York City apartment buildings carry disease-causing bacteria, antibiotic-resistant bugs and viruses that have never been seen before.

Researchers collected feces from more than 400 mice captured over a year in eight buildings in Manhattan, Brooklyn, Queens and the Bronx. The team then analyzed the droppings for bacteria and viruses.

They found some of the most recognizable disease-causing pathogens, including Shigella, Salmonella, Clostridium difficile and E. coli, as well as antibiotic-resistant bacteria and others that had never been seen before.
