Bacteria have mutated in microgravity

Scientists from the University of Houston found that the bacteria become stronger in space, and yet, perhaps more dangerous. In this regard, future long journeys in space can be compromised. Madhan Tirumalai, doctor of medical Sciences of the University of Houston and a member of the NASA astrobiology Institute, found that bacteria mutate and reproduce in the space environment. Within the most detailed at the moment of the study, the researchers observed the development of 1,000 generations of E. coli (E. coli) in a rotating container with simulated microgravity.

It Turned out that the bacteria had acquired mutations 16. Then, when they were placed next to the conventional Escherichia coli, the prototype space has grown three times larger and supported adaptive advantage in 72%. Adaptation remained even after the scientists tried to remove them.

Some changes were slightly worrisome: the mutations affect genes associated with the production of biofilms, which frequently makes cells more robust and virulent. However, not every mutation resulted in a negative effect. As he wrote Tirumalai, E. coli is still susceptible to antibiotics. That is, even if the bacteria in microgravity turn into monsters, we can still rely on antibiotics.

However, all this can be very sad for the space travelers of the future. E. coli — a relatively safe bacterium, but others can be dangerous, and diseases associated with them, can jeopardize the mission, cost lives and money if mutate in unpredictable ways. The potential consequences can be more worrying if you remember the 2013 study, which revealed that in space the immune "human cells are unable to respond to pathogens", which means "the astronauts may get sick because their immune system will be weakened."

We Need more such experiments, especially given the wild development of space missions involving humans. More and more people going into space in the framework of commercial flights. Practical issues — like how microgravity affects bacteria and our body, as well as the potential effects of isolation on mental health — must be addressed before we begin to go too far into space. This is especially true of long flights, for example, to Mars.
