Shkaplerov, an ISS expedition flight engineer who will take his third trip to the ISS in December as part of the Expedition 54 crew, said that scientists found living bacteria while they were taking samples from the surface of the station. Speaking to TASS, he said that the microorganisms might have come from outer space.

Earlier this year, during experiment "shape-shifting" was also been detected in bacteria in the near-weightlessness of space, and is believed to help the bacteria survive.
Some of the bacterial cells were also spotted producing membrane vesicles, small capsules that form outside of the cell walls and act as messengers for cells to communicate with each other.
