Scientists sent Salmonella into space, and it came back much deadlier

After the shuttle returned, mice were given varying oral doses of the salmonella and then were watched.

After 25 days, 40% of the mice given the Earth-bound salmonella were still alive, compared with just 10% of those dosed with the germs from space. And the researchers found it took about one-third as much of the space germs to kill half the mice, compared with the germs that had been on Earth.
