But there is some good news. "For us to catch bacteria from another traveler through things that we touch, the pathogens must survive environmental conditions in a plane," smartplanet.com reports. Scientists suspended some E.coli and MRSA, the contagious illness hospitals dread because of its easy transference from patient to patient, in a saline solution, then simulated sweat and saliva. Then, to see where these pathogens lived longest, the team placed the suspensions of the two pathogens onto a sample of commonly touched surfaces: rubber armrests, metal toilet handles, plastic tray table
