DRAFTING.- Researchers at the Laboratory & # 39; the Jet Propulsion & # 39; NASA f & # 39; Pasadena, California, USA, have found strains of & # 39; bacteria isolated on the International Space Station (ISS) that were resistant to many drugs, health f & # 39; future missions.
According to the study published in the journal BMC Microbiology, five types & # 39; Enterobacter bugandensis identified in & # 39; samples taken from the toilet and platform & # 39; exercise by ISS in 2015. The genetic composition of individual strains were detailed and compared with & # 39; All available public genomes & # 39; Enterobacter gathered in the World.
The result showed that the genomes of the samples & # 39; ISS were genetically very similar to terrestrial three strains & # 39; E. bugandensis recently identified as causing infections in & # 39; birth and in women & # 39; older patients & # 39; complications.
Analysis of the functional and antimicrobial resistance of the five bacterial strains demonstrated their resistance to the antibiotics used five most & # 39; often – including peniċillina- and two of & # 39; "Intermediate resistance". This pathogen is usually in the intestinal tract of humans, in wastewater and soil, and is linked to & # 39; wide range & # 39; Nosocomial infections.
Dangerous or not?
Recently it has been observed that bacteria competition to acquire foreign genetic material increase mikrogravità and increase its resistance to metals and antibiotics, factors that may predispose sources & # 39; LES to greater virulence in the future.
The researchers predicted b & # 39; computer analysis & # 39; 79% probability that can cause disease to humans.
According Kasthuri Venkateswaran, main author of the research, if the ISS organisms cause disease or not and how threats represent, depending on a variety of & # 39; factors (environmental, space, etc.).
"Further studies are needed & # 39; in vivo & # 39; to distinguish the impact of the conditions of IAS can & # 39; have on pathogenicity," he concluded.
