Antibiotic-Resistant Genes Hitch a Ride in Just Two Days

When travelers return from a journey, they usually hope to bring back some souvenirs, photos and maybe a slightly different perspective on the world.

But, they may be bringing something more harmful back with them as well. Not only did tourists bring back genes that rendered their gut bacteria resistant to antibiotics, it took as little as two days for it to happen, according to the results of a study presented recently at a conference of the American Society for Microbiology.
