Spacex has just launched its crew -11 mission into space, and with it, a ‘secret’ member: disease -causing bacteria. Or, at least, such bacteria will be growing in ISS very soon.
The crew will study the effects of microgravity on the bacterial-killing virus.
As Space.comBacterial strains included in the study. Koli, Salmonella Bongori and Salmonella are typhmeurium. He will be studied by NASA’s crew -11 mission, which successfully exploded in space on Friday (1 August).
‘Jean in space’
A study developed by scientists at the Sheba Medical Center in Israel in partnership with US-based space tech company Spacetango will investigate how microgravity affects the development of some bacterial species that cause diseases in humans, Space.com Informed
NASA said that ‘Jean’ in Space-12-competitions in which students in grade 7-12 design DNA experiments are flown at the space station- ‘ The effects of microgravity on interaction between some bacteria and bacteriophages (virus infecting and killing bacteria),
The US Space Agency said that bacteriophages are already used to treat bacterial infections on Earth.
‘Reduction on antibiotics’
A specialist stated that the experiment can help establish a foundation that can focus on “reducing dependence on antibiotics”.
The scott Copland of Boeing, and the co-founder of the gene in the space said, “This investigation can establish a foundation to use these viruses to treat bacterial infections in space, possibly reduce dependence on antibiotics,” said the Scott Copland of Boeing and Jean’s co-founder said.
How will the study be conducted?
Researchers will develop various strains of bacteria under microgravity (in space), Space.com Informed
Researchers will analyze how space condition affects gene expression Viral and antibiotic resistance,
Bacteria will be stabilized and frozen at -80 ° C. The samples will then be returned to Earth to evaluate how they have separated from the same bacteria grown on the planet of the house.
This is the second arch space lab experiment, and the first which will be in ISS.
What do researchers expect?
Researchers behind the latest ISS-Bacteria Mission have allegedly expected to bring domestic data Help to curb the spread of infectious diseaseOr at least help experts find ways Prevent bacteria from developing antibiotic resistance.
This is important because antibiotic resistance in bacteria is called a major public health problem. This occurs when some disease -causing bacteria develop the ability to retaliate the effects of antibiotics, causing drugs to be ineffective in treating infections caused by those bacteria.
Meanwhile, Scott Copland said, “Phase [Bacteriophages] Human health produced in space may have a profound effect for the stability of microbial control and long -term distance missions. ,
“Phase therapy tools can also bring revolution Manage bacterial infection And Microbial ecosystem on earth“He said.
In addition, this experiment will allow researchers to first map, “systematically and molecularly how many pathogenic bacteria in space change the profile,” was said by Space.com.
“The insight we achieve will increase our understanding of infectious diseases risks in space travel, and will also expand our knowledge. Gene regulation And Bacteriology In general, he said.
In addition, data on genetic changes in bacteria will provide more clues to researchers from expecting how they once work inside a human, whether it spreads rapidly or their possibility of being around our treatment: both on space and earth.
Is it already known?
Scientists have already studied how the growth of bacteria is seriously affected.
In addition, NASA’s research is already running to study bacteria in space in general.
“We know that the position of the space affects the behavior of bacteria, in which they grow genes, and get symptoms such as antibiotic resistance or viralies,” said Ohad Gall-Mor.
According to the report, human genes sometimes express themselves differently in microgravity situations.
Scientists have linked such an environment to the early damage of the muscles seen in astronauts, and even the possibility of developing skin rashes.
