Five Strains of Drug Resistant Bacteria Inside the International Space Station

Space faults do not already harm the astronaut team in ISS, while bacteria are likely to be pathogenic in humans at 79%.

The International Space Station (ISS), 250 miles away from the globe, is home to a group of scientists who live in the orbital outpost and a host of microbes inhabiting astronauts and research facilities. Among these microbes, scientists have recently discovered five strains. Enterobacter – A drug-resistant hospital beetle known to cause a number of dangerous infections, reports RTA.

The fact that microbes can be found in the ISS is hardly revealed – NASA said a few years ago, at the Jet Propulsion Laboratory in California (JPL), rop There are bacteria in places, even where people are ISS . The space station published a study of microbes in the dust particles collected from air filters.

Still Finding Five Different Kinds Enterobacter Given the drug-resistant profile of the bacterial strains in the orbital laboratory, in particular, it may pose a threat to future space station flights.

By Phys.org, five strains Enterobacter It was isolated from the ISS in March 2015 and was uncovered in the facility's space toilet and on the exercise platform used by astronauts to stay fit and struggle with muscle atrophy in a microgravity environment.

After discovering these bacteria, JPL initiated a study of the genetic structure of each strain, all of which were genetically similar to all three. Enterobacter Newly identified strains in the world. Known as Enterobacter bugandensisJPL microbiologist Kasthuri Venkateswaran said in a statement that these three bacterial strains an cause disease in neonates and have a conciliatory patient admitted to three different hospitals Kast.

Writing in the journal BMC MicrobiologyVenkateswaran and his colleagues emphasized that the newly established ISS microbes are not harmful to their existing teams at the space station. However, computer simulations carried out by the JPL team, Enterobacter bugandensis The probability of being pathogenic discovered in space is 79% – this means that astronauts can infect and lead to disease.

Sonuç Multiple drug resistance results were given for this ISS E. bugandensis We have increased the likelihood of genomes and the pathogenicity we have detected, which are potentially important health issues for future missions, lar said the author of the JPL Biotechnology and Planet Protection Group. Nitin Singh.

”However, it is important to understand that strains found in ISS are not virulent, that is, not an active threat to human health, but something that needs to be monitored.“

Scientists have compared five of them to determine the genetic profile of space beetles. Enterobacter bugandensis about 1,300 genomes strains Enterobacter The strains collected in the world. The analysis revealed that ISS bacteria were resistant to the five most commonly used antibiotics, including penicillin and oxacillin. In addition, microbes appeared to be resistant, moderately resistant or susceptible to four other antibiotics.

The new study showed that hospital errors in the ISS could lead to problems for future astronaut missions, while the team stressed that more research is needed to determine how infectious it is. Enterobacter bugandensis can be in space.

Venkateswaran, V E. He pointed out that an opportunistic pathogen, such as bugandensis, causes disease and how much of a threat depends on a variety of factors, including environmental factors.

Unique conditions in ISS, including micro gravity, space radiation and high levels of carbon dioxide, are known to increase the resistance of microbes to antibiotics. RTA. This means that Enterobacter bugandensis Over time, it can become more deadly.

By antimicrobe.org, Enterobacter bacteria can cause a wide range of infections that can affect the lungs, lower respiratory tract and urinary tract. These microbes are also known to produce intra-abdominal infections, as well as ophthalmic, skin and soft tissue infections. Special strain Enterobactercalled E. sakazakiiIt was associated with sepsis and meningitis in newborns.
