Scientists have discovered aboard the International space station (ISS) bacteria Enterobacter, strains of which can infect people with weakened immune systems and have a strong resistance to antibiotics. This publication reports Science Alert.

Microorganisms were detected among samples taken in the toilet compartment with equipment for exercise. The fact of their discovery is of serious concern to specialists.

The ISS even initially not dangerous to humans strains due to the specific environmental conditions (microgravity, cosmic radiation, high concentrations of carbon dioxide and the permanent presence of people) can lead to serious consequences.

The results of the genetic analysis of microorganisms showed that the genomes of five strains discovered at the station, similar to the three earthly strain of the bacterium Enterobacter bugandensis. It is the causative agent of diseases in newborns and patients with weakened immune systems. “Space” bacteria resistant to several antibiotics, including Cefazolin, cefoxitin, oxacillin, penicillin and rifampin. In addition, they have different degrees of resistance to other antibacterial drugs.

Although the identified strains do not show pathogenic properties, they are 112 genes associated with virulence, course of disease and suppression of the immune system. The results of computer modeling showed that there is a 79% chance of transforming bacteria in the microorganisms that can cause infection in humans.
