The analysis showed that all five strains of the mysterious bacteria found in the space station belonged to a species, called Enterobacter bugandensis. They resembled the genomes that infected newborn babies on our planet, raising concerns that they too could threaten the health of astronauts.
Astronauts aboard the International Space Station are coexisting with a colony of "space bugs," which could pose a risk to future space missions, according to a new study.
According to researchers at the California Institute of Technology, who published their findings in the journal BMC Microbiology, the outpost is home to five varieties of Enterobacter, a rod-shaped bacterium that resembles infectious organisms that infected hospital patients, including newborns in Africa and in the north. America. Microbial samples were taken from a bathroom and exercise area at the space station.

"We revealed that the genomes of the five ISS Enterobacter strains were genetically more similar to three strains recently found on Earth. These three strains belonged to a species of the bacterium, called Enterobacter bugandensis, which caused disease in neonates and the patient was hospitalized in three different hospitals (East Africa, Washington State and Colorado), "said Kasthuri Venkateswaran, a senior research scientist at the lab who commissioned the study.
The research team believes that bacteria in their current form do not pose a threat to human health. However, they warn that "space bugs" should be monitored as they could pose a risk to future missions.
Although ISS strains appear to be non-virulent to humans in their current form, the authors warn of a 79% likelihood that they may cause disease. However, since the scientists used computer analysis to make the prediction, they recommended more research on living organisms.

Robotic arms link cargo vessels to International Space Station
Washington (UPI) November 19, 2018
A robotic arm successfully docked the Cygnus cargo ship on the International Space Station on Monday, the second shipment of supplies in less than 24 hours.
At 7:31 am Eastern time, the vessel was successfully replaced by the Canadian robotic device called Canadarm2, assisted by astronauts from Expedition 57, Serena Auñón-Chancellor of NASA and Alexander Gerst of the European Space Agency, according to to NASA. . The third member of the crew is Russian cosmonaut Sergey Prokopyev.
