Could the superbugs on the International Space Station be a new breed of a hidden assassin & # 39 ;?


Researchers who found birds living on board the International Space Station have called for urgent research to the extent to which space affects their development.

Scientists in NASA discovered that there were five different types of Enterobacter found in the ISS toilet and exercise area.

Previous studies have shown that when they are exposed to conditions in space, bacterial mutation can become overlap & # 39; as they adapt to their new environment.

Scientists in NASA have found that five different types of Enterobacter, which were similar to hospitals, have found to find the International Space Station


A recent study in research at NPJ Microgravity found that one bacteria was well-earned over a dozen conversations when it was exposed to space, and that these changes made it better to reproduce.

Astronauts on the ISS board have already come across thick biped bacteria on their growing equipment faster than custom.

NASA experts have called for emergency research to the bugs.

Given the multi-drug resistance results for these ISS genomes and the increasing chances of pathogenicity that we have indicated, these species could be important health considerations for future trips, & # 39; says Dr Nitin Singh, the first author of the paper.

And, however, it is important to understand that the strains found on the ISS are not burdensome, which mean that they are not an active threat to human health, but there is something to monitor . & # 39;

However, according to computer modeling, there is a 79 per cent probability that they will develop a human pathogen, and cause a disease.

On the Earth, some types of Enterobacter can infect patients with incentive in intensive care wards – and have high objection to antibiotics.

The JPL researchers compared their antibiotic resistance to the three clinical species, and found that the space Enterobacter was resistant to cefazolin, cefoxitin, oxacillin, penicillin and reffampin, and had varying degrees of objection to others.

They also find that, while the Enterobacter strains of a space station are not currently pathogenic, they have 112 genes common to the clinical strains, which are associated with virulence, disease and defense.

Microbiologists with the NASA Jet Propulsion Laboratory analyze regular samples of microbes that are collected regularly from the space station to see if the space environment affects their populations in any way – and also to see if they are at risk the health of the astronaut, or the fine tool.

To show which species of bacteria were present on the ISS, we used a variety of methods to characterize their genomes in detail.

We revealed that genomes of the five IOB Enterobacter strains are genetically similar to three types of news found on Earth, & # 39; says the microbiologist Kasthuri Venkateswaran.

These three strains belong to one species of the bacteria, the name Enterobacter bugandensis, caused to cause diabetes and compromise patients, which were admitted to three different hospitals ( in eastern Africa, Washington and Colorado).

Samples were collected in 2015.

And whether an opportunistic pathogen like E. bugandensis causes disease and how much threat it is, depending on a variety of factors, including environmental ones, & # 39; says Venkateswaran.

Further in vivo studies are needed to identify the effect that conditions on the ISS, such as microgravity, other space, and factors associated with a spacecraft, on pathogenicity and virulence.
