The NASA scientists recently found bacteria resistant to antibiotics in & # 39; one of their supposedly cleaner facilities: the International Space Station. The organism is not dangerous to humans, but that is resistant makes the disturbing finding.

The bacteria is a strain of & # 39; Enterobacter and appeared in the toilet & # 39; the station. NASA conduct periodic genetic tests of bacterial population coexists with & # 39; astronauts in orbitanti laboratory. No place where humans is completely free from bacteria accompanying, but the ISS is particularly inħosforta place for microorganisms. The mikrogravità, the excess of carbon dioxide in the air and the highest levels of & # 39; radiation are not exactly the usual environment for bacteria.

The race & # 39; Enterobacter found in station is genetically very similar to strains found in three hospitals which caused problems of & # 39; health to patients & # 39; compromised immune systems. The organism was found in 2015 and in & # 39; those years caused no problem for astronauts because the measures & # 39; hygiene aboard the station are extreme and astronauts to climb on orbit always enjoy good health.

However, there is still cause for concern. The researchers who wrote the study bacteria newly published warning that the organism has a chance & # 39; 79% of & # 39; changes in & # 39; variant able to infect humans if the right circumstances exist c. The organism is completely resistant to common antibiotics such as penicillin five, cefazolin, or oxycillin, and has some resistance to others.[[[[BMC Microbiology by & # 39; Scientific Alert]
